Are your brakes squeaky at the moment? 👇
big ye
What about rim brakes? Is there a way to make them stop squeaking or is there any good rim brakes I should get?
My brakes are only squeaky in the cold temperatures 5 to -20c
@@MrShujinJonmichal You need to align the brake pads so they toe-in, meaning that the front of the pad is very slightly closer to the rim than the rear of the pad.
no, just changed pads because were contaminated :(
howling brakes are sometimes a benifit. Nothing gets dog walkers on a bike only trail out of your way quicker than a set of howling brakes.
Haha! That's certainly true! 😂
What makes a trail “bike only”?
@@krinkedsurface American constitution. You should read it sometimes.
WD-40?
"Use your thumbs to straighten a disc" 😱 Doddy may have something to say about that 🤣
My brakes squeak so loudly that the whole night wakes up when I brake 😂, but I don't do anything because I find it funny
I love Anna,, the sound of her voice, her knowledge, her riding... great addition to the team!!!
Aww, thanks! - Anna :)
Came to the comments to say the same thing!
Short, straight forward, helpful. Nice Video!
Great tips on brake issues. I could listen to Anna's voice all day long! Woo!🤘
Thanks for the support! Anna made some very great points in this one!
Thank you so much for doing this video, it will help me sort my son's brakes out
I usually just lube them up pretty good, helps with the speed as well…
We actually had a customer spray wd-40 on his pads because the were squeaking XD
@@derekduchene9242 I had silicone spray on my pads by accident. I soaked them in ispropyl alcohol for 2 days and burnt away the alcohol….still not 100% good again…
@@laser_simon922 once there was WD-40, oil or similar on your pads you can throw them away. Pads soak that stuff up like a sponge.
Sometimes, Events discs can‘t be cleaned 100% 🥲
@@derekduchene9242 def dont use wd-40 i learnt the hard way how bad that is. It works to stop the squeaking but it has the effect of also making your brakes useless.
wonderful, thanks so much!
I gave you a LIKE 👍🏻😊 - very good straight to the point video
I solved my alignment issue, I get em dead on perfect every time.
I drilled and tapped a 3mm hole into the side of the caliper bolt post ... On both sides.
I threaded in a 3mm grub screw that adjusts alignment and lock the caliper in place.
It can't move when locking down the bolts.... Perfect every time!
Thanks muchly, Anna - star advice indeed! 👌🏻
Happy to help! 🙂
Thank you,all very clear. I really must go out and straighten my rear rotor.
Thank you, Richard! We're glad you found this video useful. Good luck with fixing your rotor!
Beautiful and smart mtb doctor..lol.
Thanks for the tips..👍
I bought a new COTIC BFeMAx and the first ride the next day, the weather was terrible after about 20miles the brakes started squealing but thought nothing of it. When I got home and cleaned it, noticed the rear pads were down to the steel. That's pretty good going for 20 miles on a new bike.
Bikespeeds gives us a good analogy. Those dirty rotors with black rings.. are just like vinyl records. The grooves rotate, the brake pads make the music, our forks are speakers and our frames are.. amplifiers!
Thanks Anna all good sound advice.
Glad it was helpful!
Thanks for the video, that was a good explanation, especially the part where brakes sometimes just sweak in wet weather. A lot of people don't know this.
Aligning a caliper:
Putting the brakes on will not necessarily align the caliper... It applies the same pressure on both side pots... but if they are not centred already there is no force that will move that caliper left or right unless one pot is sticky... and then things just get worse.
So... (note: we're assuming this is a hydraulic system, not a cable one... Personally I would rather run V-Brakes over cable disk on anything other than a slow road ride!!!!!!!!!!)
If you loosen the bolts and leave the brakes off, look at the back of the disk rotor where the rotors outside edge enters the caliper...
The rotor without any load on it, should be smack in the middle of the gap in the caliper body (don't confuse this with the gap between the pads as they may still be off centre)
You should find you can push the caliper left/right and lightly tighten the bolt at one end, then do the same at the other.... the result is the rotor should now be dead centre in line, right through the caliper. Check out the view at 2:52
Once done... tighten the bolts... re check the rotor is still centered (both at the front and back)... and put the brakes on a few times...
If everything is good... the rotor should barely (if at all) move when the brakes are applied, and when released - the rotor should be clear of the pads and rotors when the wheel is spun.
(This is a good time to make sure the disk isn't warped... it should not 'wobble' back n forth in the gap when the wheel is spinning).
If the disk moves sideways you may have a sticking pot (or those god awful cable brakes and you need to manually adjust the static side pad... or cable adjuster... or cable length etc... and some numpty tried to tell me cable disk needed less adjustment than hydraulic... I haven't adjusted mine hydraulic ones in 2.5 years other than fixing a sticky lever piston, and one oil change a couple of weeks ago. (And my Foes lasted nearly 20 years with a couple of changes.. and it runs Olive Oil !!!! and now has a piece of innertube as a bellows... ok u try and get 1998 Magura Gustav parts during covid.
So... did I miss anything.... Maybe that you could do a fluid change while your at it... and if your XT lever sticks in.. sanding down the piston works... as per many U-chewb vidieos.
Oh...and for glazed pads... don't forget to brake clean them as well, it may have been oil contamination that led to the heat/glazing.
I couldn’t be bothered to carry on reading this long boring post
@@Bianchiboy Incredible. q8)
Previous owner of the bike I just bought tried to get rid of the noise with lots of oil...
I just put new pads in.
If you dont have any liquid to use but for some reason have sandpaper, use the sandpaper on the pad to clear of the dirt or olie... you can also use the sandpaper on the brake disc. I did it a few times and finaly it works but ofc you do lose some of the brake pad.
Nice looking bike
First time hauling the bike in my pickup truck I had front brake noise that ride. I'll never hang the front wheel over the tailgate again unless it's totally warm and dry out.
One thing i like to do if my pads are glazed is to sand them and then also sand the rotors real good too and rebed the brakes usually can go for awhile before pads need to be replaced
I just burn em with a troche.
I have a Scrapyard - Budget - Project - Trekkingbike ... and the brakes sound ungodly, but they are setup as correctly as possible with given hardware
Galze....
My pads glaze like sh*t
I guess i pull them to hard....
But every ride i get glazed pads... looking forward to change the brand of pads
It has its benefits, hikers will hear you coming. You don’t need to invest on a bell
What size are the hub cones?
Thanks, I keep some isopropyl alcohol in a small spray bottle just for cleaning my rotors and brake pads. My bike has SRAM code brakes (4 pistons) and one of the pistons seems lazy. Any tips on how to make the pistons work evenly?
Hey Linda, to solve a sticky piston drop the wheel and pads out, and do your best to hold the other pistons in place while you pump the brake (we tend to use plastic coated tyre levers for this). Be careful though, you want to pump the brake enough to free the piston and bring it out of the body a bit, not fire it out completely and drain the brake of all fluid. Once the inner surface is exposed, clean with isopropyl alcohol and push it back in. Pads and wheel back in, pump the brake to reset the pads and it should be job done!
The trail condition is dry and my mtb makes noise when I applied the brakes while going downhill(steep hill) and it is howling noise what does it mean?
I been chasing brake noise for a while on my older hardtail. Turns out that at my current weight the frame has just enough flex to push the rotor over when I weight the pedals hard to one side or the other
More cycling is the fix then?
@@TheWebstaff 🤣🤣🤣 that's right!! It's been a rough winter!!!
Okay, so i have tried all of this with no luck... what do i do? replace?
I need that bike 🤤
Curious: we toe-in cantis (in part) to silence them, why do we not toe-in disc pads? Seems like it would have the same benefits #askgmbntech
Anytime I’m starting my ride both front and rear are super loud and not strong at all, I resolve this by braking hard whilst pedalling downhill until the squeaking stops and my brakes work good again, this only works for my rear wheel though and not the front brake, anyone got any tips?
Hi, i tried everything to stop this annoying noise, I’ve changed the pads with new one, i cleaned the rotors and still have it. I start to think, that my problem is connected with the pads, because the have cooper inside. After longer ride and use they stoped , but on the next ride the noise is still there....maybe I should try with resin pads.
Do you need to hold your brakes down for the brake caliper alignment.
Is the "cicada" noise normal?
Mine only squeal when I ride in the rain. But when I ride up bush in the mud & wet they don't squeal.
Whenever im braking my rear wheel i can hear some rattling sound and i can feel my cranks shaking alittle bit
Sounds like some weird feedback through the chain! It could be that your crankset is a little loose or that your chain is super worn and the rollers are vibrating around a bit? It could be other things too but we'd check both of these things first 😅
@askGmbn Can i ask? Since Shimano was known to be best brand to produce the high quality product even at entry lvl.Can the new Deore mt420 brakeset ( piston) is capable of Enduro/All Mountain type of Discipline?
In short, no. They look and feel as cheap as they cost. Upgrading from mt420s to SLX callipers has been the best upgrade I’ve made on my bike so far
My deore m6120 have plenty of power. Almost as much as my codeR on my other bike. If you’re fast/ heavy or both, go atleast 200mm rotors front and rear.
New pads, clean rotor & noise free for a day or 2. Then the screeching comes back😂A problem that cannot be solved unless you take the brake completely off and just use the front👍🙂
Squealing rotors are a good thing, you can scare the pedes.. euh, notify the hikers without having to yell or ring a bell.
Im running shimano slx and xt on two bikes. both have the problem that even after a nice ride with no noises and all i put them in the garage and when i take the bike out the next day or whenever the breaks squeal and breaking power is near to not existant. it takes several minutes and many breaking manoeuvres to get them quite and working again. that cenario continues and repeats itself everytime. what am i missing ? (i tried cleaning with break cleaner and sandpapering the pads already)
i`m happy about suggestions
@H27W i am running the original shimano pads. i think they are sintered. unfortunately the weather condition doesn't have a big affect on the issue. i will try out organic pads when the current nes are worn out.
Get larger brakes and better pads and rotors. Equal pressure on pads and distance from pad to rotor to really fix
I have tried all these methods and nothing works in the rain my brakes always squeal, even my callipers brakes did the same mainly the rear. Really annoying
Mine are quiet but when pushing it on foot it then squeaks
When using Isopropyl alcohol, do you use it pure or diluted? If yes at which dilution?
Personally I'd just use it undiluted, the purer the alcohol the better.
Edit: Just to be clear, 80% plus isopropyl is probably overkill but it won't do any damage.
Yes.
I use resins pads, don't get much noise. I do ride over 12k km each year.
Mine keep glazing over after every ride. Have to give them a light sandpaper and re-bedding every time 😅
Too much hassle doing that!
3:51 If the pistons are getting closer to the rotor your lever should not be getting closer to the handlebar (unless, you are using some cheap kind of hydraulic brakes that i don't know of)
Hydraulic brake systems have a reservoir that is specifically designed to compensate for pad wear, and that is also one of the reasons why you can't just install new pads in without forcing the oil/DOT fluid into that reservoir.
Indeed. I would suggest levers getting close to the bar would indicate a leak or air in the system
@@annegrey-blackman5934 I agree. Air in the system could be due to the way you store the bike for long periods of time. Always make sure the reservoirs are placed higher than the calipers to ensure no air pockets can travel in the hoses.
Where does GMBN staff get there brakes, handle bars, grip’s, and clothes that they use personally for yourselves? My wife has small hands and I need to get her smaller grips
Thank you
Hi Will. I cut my handlebars down to suit me. My grips are Ergon "Slim Fit". All my clothes are from the GMBN shop. You might find some small rider tips in my other video too, here: czcams.com/video/H-s1eevGuZE/video.html Thanks, Anna. :)
@@gmbntech thank you very much.
Just got back to biking after many years of hiatus. Used a family bike before with rim brakes and never had squeaking, got a new Trek bike with disc brakes and it squeaked after a couple of rides. Did the cleaning, sanding and alignment but still squeaks.
It kinda boggles my my mind that just using the bike would cause noise on disc brakes:
Contamination? So I guess I can only bike in the most pristine of places?
Glazing? So I guess I won't slow down until the last second?
Me too, cant get rid of the noise no matter what..A total pain in the arse.
@@hartleyhare99 This year I replaced the stock pads with MTX Red Label. Rode about a dozen times already and no noise at all! Check it out!
My bike came with shing shing brakes from the factory😭
Guys idk if I can reccomend Radon, the XL has only 481 mm of reach and my legs are almost hitting the bars at 6'4
#AskGMBNTech
I think I have a very unusual problem with my front brake. So I put new pads 2 rides ago, and on both rides, as they got heated up the braking power was amazing, butafter one day or less, the brakes squeal and dont work great at all. Any ideas what could be causing this and how to fix it?
Glazed pads, or you cooked the rotor
@@CHINGLAW21 what do you mean by cooked the rotor? I know the rotors are worn but still braked fine before
The most common reason for brake squeal is "Sram"
What kind of bicycle you have looks very strong and comfortable please give me the brand name and model number.
I've never heard of the first method of lining up a caliper. I just sight em but I'll definitely try that out next time. Would save a lot of back and forth if it works.
I've never managed to clean contaminated pads. Tried isopropyl alcohol, brake cleaner, acetone and MAP gas to name a few. Has anyone found their pads get contaminated if they don't ride that bike for a while? It's happened to mate's bikes and mine with all makes of pads.
You can just burn em with a fire torch. Both disc and pads.
Or bake in your oven for 20 min at 200 degrees celcius
The solution is just to ride faster so the wind noise and the sound of your own giggling drowns out everything else.
Good day GMBN can you please share some information on bicycle chains brands reliability and quick links brand like SHIMANO,KMC,YBN,SRAM,CONNEX, and chain buying investment thanks DLC, GOLD, SILVER.
Getting some snow into the braking system results to some lovely noise.
Was that Jessica Strange on the howling bike?
I dont mind noisy brakes unless its my car or any of my family's vehicle
Can dust contaminate brakes?
It is possible, but not likely. Unless you lay your bike down in the dust it may squeak a tiny bit otherwise, the dust particles are so small and won't stick very easily the moment you grab the brakes all the dust will be brushed off or will fall off from the micro vibrations your brakes make.
@@kelvinelrick807 Well what about like riding in a Canyon conditions, where dust is everywhere in the air?
In our experience it definitely contributes! We've done bikepark seasons where constant dusty conditions (and bikepark braking - i.e some dragging in between braking points) form a bit of a glaze on the pad and rotor. Usually solved with sanding of both pad and rotor with a light grit paper.
@@gmbntech thanks GMBN Tech for reply. So now i should cover my bike with a rag or something to protect from collecting dust because i live in a really dusty city
How is it that the tech team get POC and the EMBN get BELL
We've got different channel sponsors :) They're listed in the description of every video 👍
@@gmbntech so POC are interested in putting their name in front of people who fix their own stuff and BELL is interested in being seen on the trails where the likelihood of falling off is much greater. OK
The only reason I want non squeaky brakes is cuz I want to do an endo
Deuble D for tea
Blake, Olly and Brendan did a video on this a while back, no brake noise at all…. czcams.com/video/qO92XrwXoY8/video.html
I have a v break bicycle 🙃
As much as i love GMBN and all the presenters old and new, the topics are being recycled over and over from one presenter to the next. No offence Anna, if u are reading this, I do have some ideas to share. how do i reach you?
They’re DISCS helicopters have rotors
Upgrade to hayes dominion brakes and you'll never squeal again
No issues with assembly for me czcams.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L but I could see where some might benefit from using an experienced bike assembler/mechanic. I'm an older rider starting back after a 10 year break. This bike exceeds my capabilities and has been easy to get comfortable riding. I'm mostly on easy trails with almost no street riding and have not been disappointed with the performance of the bike. My fitness level is far below what I previously rode with and because of that the mileage is going on the bike slowly. While I'm losing weight slowly, the bike seems to tolerate my 220 pounds just fine. The bike has been used by several family members ranging from 5'5" - 5'9".
Switch to organic pads
If they're noisy, simply grease them. I guarantee they'll immediately become silent 😉
And useless lol
Couple of mm???
I did that but my brakes still make noice ☠️
O
Any brake, when wet, will be noisy.
Just put oil on the rotors.....
Cars and motorbikes don't often suffer squealing brakes, so why bike brakes!?
Thinner discs on bikes mainly, but also the compound.
Best way to stop noisy brakes.
Just remove them.
Who needs brakes?
No, don’t use your thumbs to straighten your rotor. The oil on your skin....
As a Yank, I do appreciate a cute Brih-ish gal ooh knows oll 'bout bikes. Blimey. Me harht is goin' pih-ah pah-ah. Yeah. I may be a wanker....but I like mountain bikes and cute gurls. Shoot me, will ya?
Time to go work on my brakes and silence the howl.
How to stop noisy brakes? Don't buy hope brakes 😂
think it’s just the resin organic pads seem to just squeak well do on my e4s.
Get a pair of metal ceramic brake pads...
Problem solved!
couple of mms??? ... each pad?? sounds new to me🤔
Nobody in history ever aligned a caliper by undoing bolts and applying the brake.
I’ve done it plenty of times
Incorrect. I have. Not frequently does the stars align for it but it happens. Hell today upgrading my rotor it was dead on by the automatic way.
Seems like it's just you! However, a combination of both ways always works! Whatever gets the job done :)
