Brakes pads work by transferring part of the friction material onto the rotor. It’s all part of the bedding in process. By sanding the rotor you just reduce the braking efficiency until they bed in again ( and start to resonate once more)
Actually, the resonating is caused by dust that did not adhere to the disc surface. So clean the dust from the pads and discs with a clean cloth. That's all. No sand paper or blow dryer.
@@damianchristopher205 I think grease would be more efficient. WD40 just dries too quicky. Who has the time to lube the brake disc and pads once a week?
@thenuckinfoob01 Shimano pistons are finicky at best... And hack videos like this just make more work for bike mechanics (so maybe I shouldn't comment, that way I get more work 😉)
Been doing it for years this way, never had an issue. I pushed back maguras, hopes, shimanos and srams and never had a piston-related issue. Just gotta have a feel for it can't be forcing it too much.
Plastic levers rather than metal is going to prevent huge problems. That was the first thing that caught my eye. Also, mine were contaminated and new pads worked for me.
Use copper grease on the back of the pad, ie where the pad contacts the cylinder. Obviously this needs to be done very carefully. I haven’t had any squeak since I started doing this.
This is done on motorcycles as well. This is the proper way to remove squeaking. Squeak is just a vibration. The grease helps the pad moving freely against the cylinder and the vibration is not generated. The copper grease just lasts longer on the pad. Can't believe this is so low in the comments
legit. did the same thing with my ebike and I was so happy the squeak was gone the first 3 times I tested it but as soon as I rode home and had to brake it was back 😭 I need to buy new pads I tried it for a while by going down the steepest hills i could find and by repeatedly doing a full on emergency brake while going fast and after like 45 minutes I noticed the squeak was gone, i can brake the bike to a stop without squeaking, but I still need new pads
This actually works well. I had a customer, who pumped his calipers full of grease to make them quieter. I took the challenge, torched the pads and rotor with a torch after degreasing. Bike stopped great after.

Even new brakes can squeak. It’s good practice to clean rotors and degrease pads before installation, and that’s half of what was done in this video. Doesn’t hurt to surface polish/sand the rotors and pads to remove any rough spots from handling, shipping, manufacture imperfections/poor tolerances.

@@cataplt depends on the pads and the level of contamination. My friend's shimano pads cleaned up just fine, my tektro pads didn't get all that much better
@@cataplt Thing is, the pads have to coat there residue over the brake discs to work. There cant be any contamination on the discs of other things.

You feel the bike isn't really slowing down a lot but it makes a ton of noise. Keep going.

I didnt know what to expect when following your steps but it actually helped immensely. Not only is the squeal gone, but the braking force is now 3x compared to what it was before. Great hack. thank you big time mate.
that's easy fixed with some fine clay in water, just coat the rotor in a thin coat & the pads bed in instantly. I prefer the yellow clay that we have in some of the hilly parts of Yorkshire, but any of the finer natural boulder clays should do it.

Господа, вы же в курсе, чем по сути является скрип колодок при контакте с тормозным диском? Причина появления этого звука одинакова как в автомобильных колодках, так и в велосипедных. Наберитесь терпения, сейчас будет очень нудное повествование... Контактные поверхности пары колодка-поршень это металл, причем на колодке этот металл имеет эмалевое покрытие, предотвращающее контакт с металлом поршня. При торможении колодка ложится на диск/ротор и при не плотном прилегании к нему начинает вибрировать, что в совокупности с износом(отсутствием) эмали на обратной стороне колодки приводит к микротрению в паре поршень-колодка. Слышимый скрип это результат трения металла о металл и лечится восстановлением термостойкой и износостойкой эмали либо нанесением термостйкой, консистентной смазки на обраную сторону колодки. Прокаливание и зачистка рабочей повехности колодок, как отчищение диска/ротора, делается для удаления загрязнений, что в свою очередь уменьшает дополнительный износ пары колодка-диск/ротор, что в свою очередь позволяет избежать износа диска/ротора, что позволяет сохранить пятно контакта колодки большим и стабильным, что позволяет избежать появление шумов при торможении. Всё😊
If you dont have any of these tools, hears what worked for me. A gas stock, candle or lighter. Hold the brakepads over that heat for about a minute and allow to cool. The heat basically burns away most of the impurities that impregnate the brake pads. After it is cooled down, just lightly sand it off. Most importantly is to clean the disk breaks with some running alcohol to remove the oil from it. I did this once in January this year for a friend and he is still using the same breaks and has no issues to this very day .
Shimano Hydraulics are extremely easy to rectify if there’s any brake rub. The tough ones are Magura as the disc is often so thick that the tolerance for smooth running is very small, in fact near impossible when the brake pads and discs are both brand new
depends on the brake. BR-4770 and BR-RX400 have almost no clearance in them, so it's nearly impossible to get them to stop rubbing when new. they do get a bit better after being broken in.
The handful of times I've had to resurface my pads, I used a sanding screen so the material could fall away from the pad surface and not be ground back into it. Doing that eliminated the need to clean and heat the pads in every case.
Little side-note: don't push the pistons back with al wrench, prefer something softer, like a plastic tirespoon. Shimano uses in some of the calipers ceramic cups! Ceramic cups wil break and will leak.
Just a FYI you should always sand against the pad path. Going with will create grooves that could and will groove your pads. Going against will aid in grip and also allow the pad to knock down the high spots over time.
This is a good point! I like to spin the wheel and move the sand paper in and out across the braking surface while it spins, it creates a criss-crossing wave type pattern. This is what we do with vehicle rotors when they've just been cut on a lathe.
El problema de ruido se soluciona limpiando pero también es porque las pastillas están rozando el disco de forma dispareja y se debe centrar correctamente la mordaza.
NEVER USE TOOLS WITH OUT THE PADS IN ON CERAMIC PISTONS! If you don't have the pads in you will Crack your pistons. Trust me, I cracked 2 of mine that way.
@@NonLegitNation2 yes lol, those 4 pod xts are a nightmare to work on, as those pistons just break when you look at them... I think even the deores have ceramic if I'm not completely blind... I thought the 4 pod 6120 I have lying around have ceramic, but I'm not completely sure... And those are not really pricey.
And those shitty ceramic pistons even crack with the right tools, even with pads in, without pads and with plastic lever, they always crack... Doesn't matter what you do, you have to press them back in straight, if they go in just a little bit crooked, they are gonna break. Really annoying to get the shards out again, right mate? 😂
@@ironeinar Yeah, really annoying. in my case, I got a set of 8120s for free, so I didn't mind as much, but the shards were everywhere! the hardest part was getting the ceramic dust out of the fluid ports where the mineral oil would normally flow, a good bleed kit and an air compressor got the job done!
@@owenadair8893 yeah thats so annoying, im happy that I dont have to encounter this problem on my personal brakes, because I run Shigura, but my boss in the shop, who serviced hundrets of ceramic pistons still has problems not breaking the pistons while pushing them back in xD
I find most of my brake noise goes away just by wiping down the rotor with some alcohol. I would consider this a level 2 procedure. If you resurface the pads/rotor, you'll also want to make sure the pads are bedded in properly too.
@@IRIS.3111 The rotor can be cleaned off with solvent. For the brake pads, you'll need to remove them from the calipers, then using some pliers to hold them, cook off the contaminants with a propane torch.
Anyone else notice that the caliper he is working on is the Shimano m355 which is one of the most common caliper for failing and leaking this method is a short term fix as soon as you hear the pads up the oil will draw out of the pad material and the rotor is discolored by the oil it has absorbed and the same thing will happen as the pads they will become contaminated on the surface
Yeah. Sure. A company that has been making brakes and most other bike components for decades with thousands of engineers - should learn from a guy on the internet. Actually the pin works fine. It's not doing much - it's not actually holding the pads against the braking force (as you'll notice, none of car brake pads have a hole for either a pin or a screw). The holding is done by caliper body. Some of earlier brakes - for instance, the well-famous Avid Juicy series (3, 5, 7, Carbon) - didn't have a pin or screw at all - relied solely on placement of the pad in the caliper body and the metal spring. One of my bikes has these since 2005 - still work like a treat, even with abusive lack of maintenance.
@@JurisKankalis Cotter pins are a consumable item, they don't last forever. A good screw will last for as long as you take care of it. My bike has pads that are held in with a screw and it works like a charm.
@@lorraineschofield123 what is a castle nut and what is the cotter pin for? lol the cotterpin is to keep the nut from fully backing off. it does nothing to hold hubs or bearings.
I one-hundred % agree with this procedure. The only thing I will be very careful with is using a plastic lever to push the pads apart. I recommend you put the pads back in and use a plastic tire lever to push the pistons back into the caliper. Other than that, this is excellent video advice. And I’m a professional bicycle mechanic for over 40 years.
Yes, it will work good while it is in your service, but when your client will warm up pads while riding , pads will release grease that is hidden inside and noise and weakness will be back. Best way to solve this problem - buy new pads and clean rotor, if you can't do it try to put your old pads in a boiling water for a while.
Yeah, and I like to polish the calipers really well and go downhill holding the brakes all the way. That way I can easily forgeweld them to the rotor 🎉🎉🎉
This actually works well. I had a customer, that pumped his calipers full of grease to make them quieter. I took the challenge, torched the pads and rotor with a torch after degreasing. Bike stopped great after.
Another pro tip: adjust your caliper so it doesn't move or bend the rotor when the handle is pressed. That's a big cause for brake noise. Also makes the lever have a more solid engagement feel instead of mush.
Organic or metallic pads contaminated with grease are rarely able to be fixed. Even with acetone and sanding, the contaminant has likely soaked throughout the whole thing and the problem will reoccur after some more wear. Don’t expect this to work all the time. If you attempt, use tons of acetone and let them soak for a long time, multiple times.
As someone who has worked as a bike mechanic for 8 years, I can say this does work but won’t last long. Most of the time the noise doesn’t go unless you clean and burn off the rotor as well and if it does go it will almost always come back after a few kms. Also try a blow torch bro, heatgun won’t get hot enough to burn off the oil residue. New pads are only 5-10 bucks so honestly just replace them if the customer is ok with that
The solution for me was one I wasn't expecting at all. I performed a brake bleed and the squeal from my front rotor disappeared. I'd tried all the typical solutions before and had given up on the issue. However I performed the brake bleed and the noise went away. My theory is that air in the line was preventing my brake pads from making contact as hard as they should which is now no longer the case.
I find that while riding at a gravity park, my brakes squeak when I hit them on a long descent, but once I get into the corners and tech they go silent. I finally realized it wasnt rotor temp, it's dust on the rotors. Constant use keeps them clean, but a minute or two of minutes of full send coats them and they squeak again.
Cooking the pads is the key here. If there is oil in the pads, you have to get them REALLY hot to cook out the oil/contaminant. I usually use a propane torch

Господа, вы же в курсе, чем по сути является скрип колодок при контакте с тормозным диском? Причина появления этого звука одинакова как в автомобильных колодках, так и в велосипедных.
Наберитесь терпения, сейчас будет очень нудное повествование...
Контактные поверхности пары колодка-поршень это металл, причем на колодке этот металл имеет эмалевое покрытие, предотвращающее контакт с металлом поршня. При торможении колодка ложится на диск/ротор и при не плотном прилегании к нему начинает вибрировать, что в совокупности с износом(отсутствием) эмали на обратной стороне колодки приводит к микротрению в паре поршень-колодка. Слышимый скрип это результат трения металла о металл и лечится восстановлением термостойкой и износостойкой эмали либо нанесением термостйкой, консистентной смазки на обраную сторону колодки.
Прокаливание и зачистка рабочей повехности колодок, как отчищение диска/ротора, делается для удаления загрязнений, что в свою очередь уменьшает дополнительный износ пары колодка-диск/ротор, что в свою очередь позволяет избежать износа диска/ротора, что позволяет сохранить пятно контакта колодки большим и стабильным, что позволяет избежать появление шумов при торможении.
Всё😊
The sound of the brake cleaner spritzing is so satisfying
If you dont have any of these tools, hears what worked for me.
A gas stock, candle or lighter. Hold the brakepads over that heat for about a minute and allow to cool. The heat basically burns away most of the impurities that impregnate the brake pads. After it is cooled down, just lightly sand it off. Most importantly is to clean the disk breaks with some running alcohol to remove the oil from it. I did this once in January this year for a friend and he is still using the same breaks and has no issues to this very day
.
Shimano Hydraulics are extremely easy to rectify if there’s any brake rub. The tough ones are Magura as the disc is often so thick that the tolerance for smooth running is very small, in fact near impossible when the brake pads and discs are both brand new
depends on the brake. BR-4770 and BR-RX400 have almost no clearance in them, so it's nearly impossible to get them to stop rubbing when new. they do get a bit better after being broken in.
That will work great as long as you do it after every ride.
I like my squeaky brakes. They saved my life more than once when the car behind me wasn't paying attention
The handful of times I've had to resurface my pads, I used a sanding screen so the material could fall away from the pad surface and not be ground back into it.
Doing that eliminated the need to clean and heat the pads in every case.
Little side-note: don't push the pistons back with al wrench, prefer something softer, like a plastic tirespoon. Shimano uses in some of the calipers ceramic cups! Ceramic cups wil break and will leak.
Just use old breakpads and then a screwdriver or something like that
A goose has entered the bike chat
Honk like goose boy! 🤣
Bike guy vs average car guy
Thanks for reminding me i have to do this for my bikes since winters finished 😅
Just a FYI you should always sand against the pad path. Going with will create grooves that could and will groove your pads. Going against will aid in grip and also allow the pad to knock down the high spots over time.
This is a good point! I like to spin the wheel and move the sand paper in and out across the braking surface while it spins, it creates a criss-crossing wave type pattern. This is what we do with vehicle rotors when they've just been cut on a lathe.
Squeaky brakes brake harder change my mind
Me, a mechanic: "AWW LOOK AT THE TINY BRAKE PADS. SO CUTE 🥹"
I love scaring grandpas with squeaky brakes when they block the road
A hack i learned at my bike shop- do the same steps but instead of heat gun you spray blake cleaner and carefully light it up so the pad burn nicely.
@David to get all of the cleaner off.
I pass a torch across the pads. Takes 5 seconds. No cleaning solution. No sanding. No fuss. Easy peasy.
El problema de ruido se soluciona limpiando pero también es porque las pastillas están rozando el disco de forma dispareja y se debe centrar correctamente la mordaza.
I'm surprised we haven't engineered a braking mechanism that doesn't wear at every use, it sounds like a pretty good improvement
Like a magnetic breaking system. No need for friction
step 1: own 300 dollars worth of equipment
NEVER USE TOOLS WITH OUT THE PADS IN ON CERAMIC PISTONS! If you don't have the pads in you will Crack your pistons. Trust me, I cracked 2 of mine that way.
if you can afford calipers with ceramic pistons then you aren't the type of person who is watching a bike hack video lol, just saying.
@@NonLegitNation2 yes lol, those 4 pod xts are a nightmare to work on, as those pistons just break when you look at them... I think even the deores have ceramic if I'm not completely blind... I thought the 4 pod 6120 I have lying around have ceramic, but I'm not completely sure... And those are not really pricey.
And those shitty ceramic pistons even crack with the right tools, even with pads in, without pads and with plastic lever, they always crack... Doesn't matter what you do, you have to press them back in straight, if they go in just a little bit crooked, they are gonna break. Really annoying to get the shards out again, right mate? 😂
@@ironeinar Yeah, really annoying. in my case, I got a set of 8120s for free, so I didn't mind as much, but the shards were everywhere! the hardest part was getting the ceramic dust out of the fluid ports where the mineral oil would normally flow, a good bleed kit and an air compressor got the job done!
@@owenadair8893 yeah thats so annoying, im happy that I dont have to encounter this problem on my personal brakes, because I run Shigura, but my boss in the shop, who serviced hundrets of ceramic pistons still has problems not breaking the pistons while pushing them back in xD
Or, keep them squeeky, so the rider in front knows they're slowing you up and should let you by before there's a crash!
Valid point. Works for informing the rider behind as well.
I got jumpscared by the high pitch "HEEEEEH" man exhale.
Thank you. Good, simple and without talking!!
I find most of my brake noise goes away just by wiping down the rotor with some alcohol. I would consider this a level 2 procedure. If you resurface the pads/rotor, you'll also want to make sure the pads are bedded in properly too.
Bro I told my siblings to do some oiling on the chains and he put the oil in the calipers what should I do? Should I change the whole set?
@@IRIS.3111 The rotor can be cleaned off with solvent. For the brake pads, you'll need to remove them from the calipers, then using some pliers to hold them, cook off the contaminants with a propane torch.
@@lihtan thanks bro I will try it
The best hack is to simply smother the disks and pads with grease. It really reduces the squeak.
жиза кстати
@@DJSalih7722F that's a pretty good reply... Because then we know it won't work at all!
This is like the Alt+F4 joke, only even less funny...
Such a big brain method. Best way to care for your brakes is simply making them unusable
@@overtheatlasThe less you use them, the longer they last, so it's a good strategy. Besides using brakes just slows you down.
I just leave it so people in front know I am breaking😂
Wow! No stupid music. No long-takes, showing how to remove bolts. Nice clean cuts without (dum) fancy animations. Nice job! 👏
En España 5 minutos con la pistola de calor son una fortuna... vale menos un juego de pastillas nuevas.
Es claro que sí
Why is it expensive to use a heat gun?
@@mydearriley Expensive electricity, probably. ?
Acá en Argentina las pastillas de frenos de bicicleta son más caras que las de auto
Брат, приезжай к нам в Россию🙂
If you get bearing grease and put a good solid layer on the rotor and pads it really helps with the noise. Loosening the brake cable works as well.
Who needs a bell when youve got squeeky brakes ?
Sometimes the squeak comes from loose bolts.👍
or mis-alignment...
I quite like my squeaky brakes now.
Anyone else notice that the caliper he is working on is the Shimano m355 which is one of the most common caliper for failing and leaking this method is a short term fix as soon as you hear the pads up the oil will draw out of the pad material and the rotor is discolored by the oil it has absorbed and the same thing will happen as the pads they will become contaminated on the surface
When it rains every other day here you just live with the squeak 😂
The idea of having a cotter pin for the pads instead of a screw is... madness.
A car's wheel bearings and brake pads are held in with a 'split pins' with no problems 😊
Yeah. Sure. A company that has been making brakes and most other bike components for decades with thousands of engineers - should learn from a guy on the internet. Actually the pin works fine. It's not doing much - it's not actually holding the pads against the braking force (as you'll notice, none of car brake pads have a hole for either a pin or a screw). The holding is done by caliper body. Some of earlier brakes - for instance, the well-famous Avid Juicy series (3, 5, 7, Carbon) - didn't have a pin or screw at all - relied solely on placement of the pad in the caliper body and the metal spring. One of my bikes has these since 2005 - still work like a treat, even with abusive lack of maintenance.
@@JurisKankalis Cotter pins are a consumable item, they don't last forever. A good screw will last for as long as you take care of it. My bike has pads that are held in with a screw and it works like a charm.
@@lorraineschofield123 what is a castle nut and what is the cotter pin for?
lol the cotterpin is to keep the nut from fully backing off.
it does nothing to hold hubs or bearings.
Rather have a pin than the Shimano flat head screw.
I liked the part where he pushed the quick release handle into the spokes on the rotor 🤣🤣🤣 I'll do my own brake service thanks 🤣🤣🤣
tbf a proper QR wouldnt close enough to interfere with the brake rotor spokes. It shouldnt really matter how its set up.
What a tiny little brake pads. Awww, they're cute.
I one-hundred % agree with this procedure. The only thing I will be very careful with is using a plastic lever to push the pads apart. I recommend you put the pads back in and use a plastic tire lever to push the pistons back into the caliper. Other than that, this is excellent video advice. And I’m a professional bicycle mechanic for over 40 years.
Yes, it will work good while it is in your service, but when your client will warm up pads while riding , pads will release grease that is hidden inside and noise and weakness will be back. Best way to solve this problem - buy new pads and clean rotor, if you can't do it try to put your old pads in a boiling water for a while.
Yeah, and I like to polish the calipers really well and go downhill holding the brakes all the way. That way I can easily forgeweld them to the rotor 🎉🎉🎉
I just hold the break for a few seconds and the squeak goes away for a while
I have brakes that won't quit howling unless, probably, I replace the pads. At least I don't need a horn 😂
This actually works well. I had a customer, that pumped his calipers full of grease to make them quieter. I took the challenge, torched the pads and rotor with a torch after degreasing. Bike stopped great after.
Another pro tip: adjust your caliper so it doesn't move or bend the rotor when the handle is pressed. That's a big cause for brake noise. Also makes the lever have a more solid engagement feel instead of mush.
"replace the break pads " 😂
Aint lying. Shimano pads are crap. You need another brand and the squeek will go away. Shimanos have a poor compound that sucks up moisture
Using isopropyl alcohol and sonic cleaner also works. No other steps exept a bit of sanding is required
As someone new to bikes i appreciate the education
I had a 280 Z that could never get to stop making that sound no matter what I tried.
Проще сразу новые колодки поставить, желательно Шимано, они не шумят
если ты едешь по земле скрипеть они будут в любом случае, ибо пыль в зазоре неизбежна.
А теперь выбрось их на помойку и купи новые.
А мне нравится , скрипят только когда пережимаешь. Я их использую как клаксон😄
thats one way to resurface rotors
My bike is like that too, so I thought "oh" but it's too much hassle to do it lol
Organic or metallic pads contaminated with grease are rarely able to be fixed. Even with acetone and sanding, the contaminant has likely soaked throughout the whole thing and the problem will reoccur after some more wear. Don’t expect this to work all the time. If you attempt, use tons of acetone and let them soak for a long time, multiple times.
Agree. They might stop squealing for maybe 10 minutes of the next bike ride.
Sounds also produces in my power breaks 😂
It's like a motorcycle but tinier. So cute.
Nah I just like to put WD-40 on mine
Does it works?
@@loviecirilobalo4517 no!!! Wd-40 Is oil🤦🏼♂️
@@zvebiNmob1zer666_ nope that not oil

I find olive oil really helps to stop squeaks. Brakes don't work so good, but hey.... 😂
How to glaze your pads, now without using them! Genius
Applying to my squeaky iPads immediately!
Just grind the edges from the pads and you are good to go. And never do something like that to the disks
I just use marine grease on my rotors, it even works on my truck!
It reminded me of my friend using oil in his breaks
I swear he really did that not only breaks got worse also they made a loud noise 😂
As someone who has worked as a bike mechanic for 8 years, I can say this does work but won’t last long. Most of the time the noise doesn’t go unless you clean and burn off the rotor as well and if it does go it will almost always come back after a few kms. Also try a blow torch bro, heatgun won’t get hot enough to burn off the oil residue. New pads are only 5-10 bucks so honestly just replace them if the customer is ok with that
I use copper grease on the back of the pads. Works perfectly every time.
The solution for me was one I wasn't expecting at all. I performed a brake bleed and the squeal from my front rotor disappeared. I'd tried all the typical solutions before and had given up on the issue. However I performed the brake bleed and the noise went away.
My theory is that air in the line was preventing my brake pads from making contact as hard as they should which is now no longer the case.
Perhaps the air allowed the pad and fluid to oscillate.. just spitballing
@dielaughing73 yes. Considering you can't compress water
Well it doesn't squeeze much. It can apply lots of force without changing volume
Goddamn had my phone on full blast and it sounded like a mad elephant 😂
I find that while riding at a gravity park, my brakes squeak when I hit them on a long descent, but once I get into the corners and tech they go silent. I finally realized it wasnt rotor temp, it's dust on the rotors. Constant use keeps them clean, but a minute or two of minutes of full send coats them and they squeak again.
We have a place in florida called the vortex. It has a decent downhill section and amazing trails
The jumps downhill broke my nose even with a full face helmet once
@@Psilomuscimol come to Colorado, where you can break everything else.
I just spray a little WD on it. Silence. Almost like they aren't there
I did that on my rim brakes when i was like 13. As you say, like they weren't there. Oh, did i mention I lived on top of a very steep hill?
lol
wear respirator. brake pads still often contain asbestos in different regions
all Shimano brake pads are Japan and EU legal, so probably asbestos free.
@@AlexandarHullRichter truth
Cooking the pads is the key here. If there is oil in the pads, you have to get them REALLY hot to cook out the oil/contaminant. I usually use a propane torch
If you cover your brake pads with grease, they rub less and don’t wear out 👍
Once the pads are noisy and contaminated the only solution is trash and new ones. Also using a metal wrench in the caliper is no good.
I used that squeak as horns... good ol days
Thats how bed-in sinter pads sound when cold.
