literally will save you hundreds of dollars, by not having to replace disc rotors or pads, this is the easiest solution out and takes little to no time!!!!
its not hundreds of dollars. i bought rotors for about 20 for two , and two sets of pads for 20. did it myself and cost very little. i bought the cheap knock offs on amazon and they worked just fine.
@@bigd835 yeah i reccomend you buy new pads regardless thats what i did before following this video
The impression of the sound at 6:12 is spot on (and pretty hilarious). I'm going to buy this stuff because the squeal is the bane of my existence.
I would just like to say.. this stuff WORKS!!! I've had the craziest Noises coming off my brakes forever.. everything I tried failed. 3 bike mechanics all tried aswell.. couldn't get rid of the noises. Had to bite the bullit.. brought this purely off this video! Paid 2x in shipping what the actual product cost (Ship to Australia)
Can honestly say it was worth every cent.
Thankyou so much GC 🙏🏻
:)) that is awesome!!! im telling you me being a mechanic and working on this shit, I have had my issues with squealing brakes and this was the first prodcut to fix it everytime with little to no work involved compared to sanding rotors removing pads and all that other shit..... Thanks for watching
Do you recommend it 🤔
@@jmauds49 couldn't recommend a cycling product enough.
This video is very timely! I’ve noticed the same noise for my bike. Checking my shopping cart out now. Thanks for sharing this!
you are very wlecome thanks for watching
Thanks GC, worked like magic! No more obnoxious sounds from my front brakes. I was told to replace the rotor and or brake pads from lbs, but decided to try this product fist.
Glad it helped
Holy shit!!! You just saved me money! I was told I needed new brakes and new pads and because of the shortage, I cannot find resin disc brake pads or rotors! My rear brakes sound exactly like that and your video may have just saved my ass!!! Thanks for the tip!!!
I am happy to help
Why resin pads? These are shitty
Thanks for posting this! Cool product. What it appears to be doing is polishing off all the little micro grooves in the rotor that cause the pads to "play" on the rotor like a needle on a record. It used to be a very common thing in the automotive world, and it was overcome by using a special "glue" that was placed on the back of the pads so that they were "glued" to the caliper piston, and thus couldn't "sing." Manufactures also started putting soft metal plates on the backs of the pads, which performed the same function, by dampening the oscillation of the pads, and preventing them from singing.
I recently had a front rotor on my DH bike that was singing. As you (and others) describe, nothing worked. I ordered new pads and a rotor, but in the mean time, popped the wheel off, held it to the wire wheel on my bench grinder, and had at it, allowing the wire wheel to run as perpendicular to the rotor surface and the lines on the rotor, as possible. Problem solved, by just wire wheeling one side of the rotor. I could have done a much better job by popping off the rotor, and doing both sides....but I just wanted to see if it would make a difference to simply wire wheel all those lines that get cut into the surface of the rotor. I rode it quite a bit, even after the new rotor and pads arrived, because I wanted to see if the wire wheel trick actually worked. The brake remained silent.
I'm an engineer. Singing aka 'resonant frequency' is much more common on bicycles because the objective is low weight. Takes a lot more for a car pad/rotor to resonate because it is higher mass. Think a reed inside a saxaphone that creates sound through vibration aka high frequency oscillation. It oscillates aka makes a high frequency sound because it is very light and thin. If the reed is one inch thick it doesn't 'sing'. Good tip on disrupting the surface finish of the rotor. Another analogy is a finger around the rim of a wine glass. Doesn't work with a much higher mass coffee cup.
Diatomaceous Earth? In, say, denatured alcohol? (Stronger for solvent action than 99% isopropyl alcohol.)
Awesome 👏 Thank you 🙏 I’m gonna try it out, mine are not bad, but I want them as quite as possible, thanks again buddy
BTW…Love the special sound effects…. lol
your welcome
The sound effects are great. They are on par with your usual special visual effects.
lmao glad u liked them too
Thank you! I bought some of that paste and tried it. I had the brake from hell and was about to change the pads. I hated to change them because parts are hard to come by and I didn’t want to waste what I had. It does take some time to clean the excess off after the paste does it’s magic but worth it. Thanks for the video👍
Excellent! I am happy it worked and yes just work it through and is much easier then paying for new rotors and pads
THIS STUFF WORKS! Treated my brand new Ultegra disc brakes with it and noise went away 100%. Hopefully this brings some sanity and relaxation back to your riding 😃.
helll yea!!!! I am jsut trying to help at a cost effective way and not have ur bike in the shop for long times
GC performance gets the 2021 award for best intros
interesting, im gonna need to try this out. thanks mr GC
of course!!!
Woah, perfect timing. Front rotor started squealing a couple of rides ago. Bike shop said the same thing, replace pads and rotor. I also thought it would be a good excuse to upgrade the caliper and shifter, but parts availability still an issue
I got you!!! this will work for sure
I'd quit going to that bike shop.
Had to come back to this because my new brakes were sqeauling. I just rub the pads and rotors with acetone. Easy, quick and works a treat 👍
yea I have done acetone before sometimes it works and sometimes after a couple days it goes away
The ultimate solution and a gamechanger seems to be just going back to rim brakes.
Ive just ordered a tub from the only retailer I could find selling it in the UK. Fingers crossed for when it arrives!
So apparently the owner of the company is closing down, something with him but the product won’t be made for now which is crazy
This weird noise😂😂I love this channel
lmao thnaks for wtahcing
“Both hands on the steering wheel” brilliant! 😆
lmao I need to practice safe riding skills for eveyrone
The sound impression is spot on!🤣
thank you for your knowledge and experience
thank you for wqatching
This is awesome. Wish you put this out two weeks ago before I replaced my pads. LOL All good though. FYI - Product is available on Amazon for $18...
thank you very much!! :)
Would have been cool for me in the past, but now I am running Swissstop pads and have never heard a squeak since. Good to know for the future.
very nice and yea this will work for sure in the future
this will be great especially since l03a are out of stock everywhereeee
I know!!!!! they are impossible to find
Gonna try this out. New bike with 105 Shimano disc, front squeals horribly. I’ve had them off several times and cleaned thoroughly, but squeal comes right back. Just ordered new pads and was thinking of replacing the disc. Hopefully this works 🤞🏼Love your channel 😎🤙🏼
thank you veyr much but yes give this a try first it works right away for me just follow directions of this video ofr on the bottle and ur good to go
Also try cooper grease on the back of the pads to stop them vibrating against the pistons, something mountain bikers and motorcyclists have done for years
really? I have to take a look at it
have you tried copper grease on the back of your break pads,that works too.
Swisstop makes disc brake silencer also. It works like a charm.
I ave to take a look
Thank you GC 🙏🏽
Thanks for this info! Do you think that the product will work with Resin Pads as well as Metallic Pads?
yes they work for both as long as u do the steps right
Yo GCP love your channel it’s taught me a ton about my SL7!
I’ve looked all over and no one’s selling Squeal Out online now - can you recommend another paste? Thanks! Tim
Mannn thanks so much it’s actually very weird. The guy who makes it. Stopped making it. I don’t know why.
Dang. Any other product that works exactly the same?😂
Got mine thanks gc performance
your welcome
my breaks squeaked from the time I bought them. I had my LBS clean and check the breaks one day and it did get a lot better afterwards.
very nice but this will cure it for good
Lol i have a similar problem with my road bike when riding under the rain even without braking sometime, i checked the brake if its in the center, replace the new rotor one it seems less noisy but its still there in the front wheel, when riding under the rain, is it because of the sand and water going to the rotor when its raining made the noise?
Love the sound effects lol
lmao I got you
🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣 the brake stop at the beginning… oh soooo familiar… 😆😆😆🍻
hahahha I had to re create it
@@GCPerformance18 🤣🤣🤣🤣
Very cool tip.
you are wleocme
In Sweden we have a thing called "svinto" wich is steel wool with a tiny bit of soap on it, i take of the entire wheel and i just sit and polish it ever so slightly untill the disc brake is nice and shiny again. And then i dry it off completely and take a small amount of brake clean, or cleaning spray on the disc to remove and dissolve any soap still there. Blow out the rotors with compressed air and its as good as new!
får testa svinto :)
I definitely will get some of this stuff, but guess how much it is in Canada? lol! 69$ from Amazon wth?!? Oh well I need it. Thanks for the video! Saved!
Thank you.
Could you make a video on how to allign disc breaks so that they don't rub. For some reason mine rub more after I break hard. Could you make a video on how to fix this too? Thanks!
yea possibly in the future
new break pads for both front and back cost me like 5 euros and I used de-greaser on the discs to melt all the oil away and clean em up. it's dirt cheap and super efficient time/cost wise
Nice work!
You are so kind to be honest about it, considering it takes money out of your pocket from replacing pads more frequently for your customers.
thank you!!!
If this solves the persistent squeak on my wife's Diverge, it will be worth a lot more than the $17 that I just spent for it on Amazon! Thanks for this, and the consistently Independent content on your channel.
I have a diverge as well and the brakes are horrendously loud. I've never experienced brakes this loud before.
I got you!! It will work
@@GCPerformance18 does this potentially improve performance?
thank you i will definitely buy some of this stuff 😊
your welcome
Thanks for your help and great information
of course thanks for watching
Interesting, but I'm very sceptical about this stuff. The only trick that work for me to clean disc and pads is a complete cleaning of the rotors and pads with alcohol or acetone AND THEN finishing by heating the pads with a lighter or a small torch to burn off the oil/grease that got inside the compound. It works every time for real. But one thing is for sure; roads are full of contaminants such as engine oil or whatever so when it's wet, this oily water goes on all of your bike components, thus contaminating your pads and rotors. It's a never ending process.
im not lying to you, I have done that process, I have sanded down pads for half a day, I have let rotors soak in alchol over night.... i have used everything, no lie this product is so easy and works so well. I know it seems skeptical but ti takes all that time you would spend doing that and makes it into a 5 min job with close to a 100 percent succes rate.... we literally put mucoff lube on rotors before this video and squeezed just to see how well it worked and, it removed it everytime no extra wiork
Cleaning all the time is just plain crazy, as you said that is a never ending process. Get some CRC Dequeak, spray a little on a rag, apply to the rotor, and be on your way. Honestly 10 seconds of work.
@@charlesmansplaining what is CRC
I had squeeling brakes, driving me nuts. The front brakes got silent after I cleaned it with acetone.
The rear brakes kept being noisy. I removed the pads. They were glazed. I rubbed them on 400 grid sanding paper. I moved them forth and back about five times on the sanding paper. I reduced the thickness of the pad with about 0.05 mm. I cleaned the rotors and the pads with acetone and the it was silent again. I had to break in the brakes again.
Very nice to know
Use isopropyl alcohol on the rotors and pads when you clean your bike after each ride.
Can you recommend a link where I can actually order this product? Every link or online store is reporting out of stock or back order.
I just placed an order, this might maintain my sanity.
i got your back
I made a trip to the local auto parts store and picked up a can of CRC DeSqueak for $12. Worked like a charm. The problem causing the squeal is the pads were never bedded in right. DeSqueak will help fix that pretty quickly, in probably less than a day of riding. Everyone assumes you have to have clean brakes and scrub with alcohol but why is it some people's breaks don't squeal and they never do any maintenance? CRC DeSqueak is kind of gritty too, and a bit messy but eventually you will clean up the excess. One can will most likely last me the rest of my life.
damn nice call, I am sure there are a ton of alternatives I jsut recommend this because it is advertised for this specific use..... like bicycles but I there is a whole mess of stuff that can be substituted at the consumers own risk of course
This is awesome but dam I miss the rim brake days.😑
GCN is going to be like “should we just hire this guy?”
lmao I wish.... it would be a dream come true
that squeal is conparably comfortable! the mechanical disc brakes on my cargo bike alternate between unpleasant grinding noises, and a _really_ high pitched screech, akin to trains in the 90s, that i can just so notice, but that makes folks under 20 flinch in discomfort. despite multiple cleanings, re-allignings, and other attempts to just silence those brakes.
what do?
those pads are bad and also the rotors can be bad, they can wear un even causing them to have the pads grab weirdly
Dang if that isn't my exact bike...2019 Spec Tarmac Pro with DI2 Ultegra and Roval C50 wheels wow......weird so Short question how long does this Squeal off last?
Run Paper towrel on rotors both sides and get new paper towel dab into acetone and clean.. am its cheap
sometimes the contaminents are so deep into the pads that it does nothing and still makes a squeal
It’s a cool 12 degrees here in MI
damn that sounds horrible right now...... but also would not mind coying up next to a fire place
Interesting. I find that most bikes have cheap enough pads and rotors that it cost less to just replace them than what I'd charge for labor to clean them, knowing I'd likely have to clean them 2-3 times to get them to quiet down, and even then there's no guarantee. However, I recently picked up a new bike equipped with XTR, and the rear rotor got some contamination while assembling it, and the old sandpaper and isopropyl trick isn't cutting it. A 180mm XTR rotor and the pads to go with it, even at employee pricing, sure aren't cheap like the Tektro rotors on a hybrid, and it would kill me to spend the money before I've even ridden the bike..
I'll definitely be giving this product a shot, and if it works I'll be adding it to my toolbox to use on customer bikes in the future to save them money, and improve my work order margins.
Thank you for the video!
yea I mean to be honest the customers who have the cheaper spec bikes dont get the squeaky brakes as much because they dont ride them as much at least in my area.... we see only high end brake users coming in, so in that matter rotors alone are 160 for new ones, we have done this process now with this solution and it works well, but sometimes u just need to throw in the towel and get new rotors and pads
Have you tried muc-off's disk brake cleaner?
I have not but i have tried everything else under the sun, no lie.... almost every other company, all the tricks but they are hit or miss depending on how bad they are..... with this we literally took lub right on the rotor squeezed it onto the pads and then did this treatment and no more squeal
@6:14 better than actual squeal
hahahha I clicked it and rewatched it and I died... thank you
That looks like sl6 pro. That bike in person looks sick. Is that your personal bike?
yes that si the bike but no this is not my personal bike.... this was a customers bike who was having issues that we fixed
This sadly did not work for me. I bought a Cannondale Topstone 4 about 8 months ago and the brakes have been atrocious. I noticed this item was out of stock for awhile, and when it was available again ordered it, finally tried it yesterday and initially worked for about 10 minutes then the noise progressively came back. The squeeling/squaling and whaling have have seem to got worst with time and louder. Would it be better to try to upgrade to hydraulic disc brakes? I am tired of dealing with this problem and just want to enjoy the new bike. I almost regret ever considering a bike with disc brakes.
i have exactly the same brake rotor same brakes, tried everything out with no result. Im gonna order from that shit too, and gonna try it out asap, thanks mate.
this stuff works great!!!
this stuff works great!!!
@@GCPerformance18 it is interesthing that , this squealing happens most of the time with shimano setup, never experienced that with tektro or any other brands.
Automotive brake cleaner for the rotors and pads. I spray and wipe off the rotors with a clean rag every few rides and clean the pads after i wash the bike.
yea I dont know why the bike industry has so many issues with this when cars have had a solution for this for so long, I would think it would be the same
@@GCPerformance18 Never, ever use automotive brake cleaner on bicycle brake pads unless it specifically states on the container that it is suitable for such use. Prolonged, regular use of such a product can delaminate the pads, and if used in situ, effect relatively delicate calliper seals. Plus some automotive brake cleaners actually contain oils - which can be burnt of at the temperatures achieved by automotive brakes but will remain on, and permeate bicycle pads. Shimano and Hope specifically advise against using all automotive cleaners on their products, and instead recommend using an IPA spray.
Videos like this restore faith on humanity. Still not a big fan of disc breaks though 😁.
Just what I need, just can't get it in the UK
damn I am sorry
This thing does not seem to be available anywhere anymore. Is there an alternative?
Isn't this stuff in effect a grinding paste? I would think there are easy diy grinding/lapping pastes to make that would do the same job for very little money.
Really?
That's what i thought
I dont know this is just marketed for road bikes, I am not famialr with grinding paste but this works great and is advertised for it specifically
@@GCPerformance18 do they list any ingridients? unfirutnatley i cant buy in in europe
A DIY paste would need to not contaminate the pads, I think this is why you can't find DIY grinding pastes. No one is willing to do R&D on their own pricey bike parts.
I now need you to do the donkey brake squealing sound on every video. 😂
hahahah i got you
Lemon juice. Litterally cut open a lemon and put the natural juice on rotor and pads. Next go to a descent and brake hard. It's going to squal a lot. After just rinse with water and the brakes are new
no fucking way..... I have to try that lol
Sending the pads and rotors, cleaning them with alcohol and rebeding the brakes, does the trick every time. Also sram AXS brakes never squeal👍
ooooof I have seen some bad ones..... those pads soak up that shit and stays in thee like a sponige
I listened, but did you spray your pads with brake cleaner until they looked new? I also take a dremel with a cutoff wheel and cut small grooves like cars have and gone! This is interesting and if you don't own a dremel, this might be the cheap alternative.
@GC Performance I'm curious how much you sanded and which grit sandpaper you used.
yea I snaded them until the shine went away and sanded for like a literal 2 minutes, I forget the exact grit but pretty fine stuff.... also sprayed and aso sprayed the rotors too
Any suggestions on where to get this? Seems sold out everywhere as of 6/2023. Also any alternatives that work?
I really don’t. I guess we got in contact and the guy is slowing down production. He said he might stop making more. We’re looking for more
Toothpaste ?
Is this only for contaminated pads/rotors? My front brake always gets glazed, and squeals.
rotors are fairly easy to clean but if the pads are like crazyyyyy contaminated and just absolutely done, then what i do is take a torch right to it and burn the shit out of it and it almost always restores it back to like 75% braking power
this is like last resort
this works great
Local bike shop couldn't fix wife's disc brake noise. Many trips to the shops and we have up.
I am teling you, buy this and it wil fix the issue no lie.... it is so easy to do, I have tried everything under the sun evern going to extra miles of soaking rotors and pads in alchol but this works all the tim
Great job GC but I use the sound of my brakes like horn. If I fix their noise you own me a horn. Kisses from Greece...
hahahah kisses from florida
i use the sound as a horn too, Edmonton, Canada
@@samkadoura5851 me to Sam. Greetings from Greece...
"A cool 79 degrees " 😂🤣 where i live that would be scorching hot .
lmao dammmm that is sweater weather for me
I found that rubbing some dirt / mud on the rotor achieves the same result.
Yes. I think we as a community need to formulate a cheap DIY grinding/lapping paste.
Where can I buy this? Looks like the place you listed doesn’t sell it anymore 😢
yea I know the guy stopped making it, shit is wild and we can not make it anymore
i wonder if toothpaste would work - i have this issue on my bike at the moment but dont want to wait for shipping
Really?? What makes you think toothpaste would work…. Give me
An email if it does I would be curious
@@GCPerformance18 because its a mild abrasive
I love the squealing at 6:15
Hahahahha was it spot on?
@@GCPerformance18 perfecto 👌🏽😌
The brakes on my MTB are barely working. Pads look ok but lots of debris. My gravel bike brakes work ok but squeal so we'll see how that works as well. Going to give this a try and report back.
this stuff works great just follow the step
Can’t seem to find this for delivery in the uk without import from US at megabucks 😡😢
I am sorry :(
use a head or chest mount for your video camera, then do a proper 2 hands brake test.
yea but then it looks weird and I cant show off my skills while riding
Fire solves most problems.
I did fire a couple times and didnt work that well
Whenever I have brake squeaking issues I wipe the rotors with alcohol. Problem seems to go away.
damn ur lucky sometimes it wont be that easy
What width handlebars do you use?
I use 42cm
Rubbing compound works just as well
as a fellow bike mechanic im not saying this doesn't work for contamination, but the squeal at low speeds is not contamination. On road bikes with shimano it is due to the fact that they have finned pads so at low speeds small imperfections in the rotor will make them squeal a little bit like in the beginning in the video. For mtb most mid to higher end breaks have metallic and finned pads so the noise can also come from the small amount of metal in the pads (metal to metal so it is like when a train comes to a stop it's loud). this may work for contamination but if possible it is usually best to replace pads and rotor and if it i just a low speed squeal leave it. but this is better than waiting the 200 years shimano said on their dealer website (it was a typo but still) for new pads or rotors. great video tho!!!! :)
Yea at low speeds I believe it comes down to harmonics, the rotor is bouncing back and forth between the pads and vibrating, by the sound of it this product seems to be some sort of lapping compound, although I havent went to the website or looked it up to confirm
Thanks so much for watching :)
I had brand new Shimano Ultegra pads and rotors that were so freaking loud no matter what speed I was breaking. I tried to live with it for several 100 miles thinking the pads just needed to bed in. I began trying to clean them with alcohol to make the noise stop but nothing seemed to work. I finally found this same product squeeealll out. Applied the product and the noise went away 100%. It’s been about 1200 miles since I treated them.
@@Dave-so7sf at that point it more than likely was contamination and being that you just bought the pads and rotors thee is not point in spending even more money buying them again so a product like this would be fine.
Can this be used on electric scooter disc brakes?
yes
Chain lube sling causes these squeaky brakes. Disc not as bad as rim brakes though.
swiss stop make a brake silencer that does exactly that just in aerosol form
does it work well, because finish line makes osme and it did not work that well, have u tried thta?
@@GCPerformance18 ive been using it in my shop for the last few years and it works a treat, but you still have to clean the pads/rotor before application. Its not a cleaning product but just a Silencer. The application with the spray bottle is great, one squeez on the pads and its done. Havent tried the finish line one because i never needed to.
I found that Muc Off shine accidentally sprayed on rotors took the squeal right out. Stopping was the only downside.
really? I will try in the future
Satire achievement unlocked!
What do you charge at your shop for that service?
depending on what needs to be done but just applying it front and rear, should be like 25-30
Disc brakes are “efficient”?
Care to expand on that one?
They have more secure stopping power in the rain, descending, have you ever had a rim brake carbon wheel and it’s raining out?
@@GCPerformance18
You said “efficient”. I’m asking you to explain to us how disc brakes are more “efficient”.
I have disc brakes on my road bike. So you don’t have to convince me that they are superior to rim brakes in multiple ways. I just don’t see how ‘efficiency’ enters the picture here.
Alcohol won't do jack, they call it brake cleaner for a reason (heptane/hexane not just naphtha degreaser garbage)
Lighting them on fire won't do jack, you need to cook the oil/silicon out, so 300°c+.
Are you using metallic or organic pads? Is your caliper set back far enough to not let the pad overhang over the disc? Is your disc flexing to one side? (Non centered caliper or uneven piston forces)
Just like a car, the squeal is coming from the pads chattering in the caliper, you have to find the root cause
I have done so many tricks, this works so well in little time
If you're so knowledgeable, why not make a step by step guide to check each of these potential root causes?
@@mitchellsteindler the design is inferior, needs more mass to stop the vibration. More mass = more weight. That’s a no no with the weight weenies. Unfortunately can’t convert back to rim brakes, no such issues prevail in rim brakes. Good luck fixing a design issue.
Looks like tooth paste or headlight lens paste. Follow up: Tried it out. Put tooth paste on rotors, go for a ride using brakes lightly. Hosed off with water. Dry off with a leaf blower. Squeaks gone.
Mother’s mag wheel polish also works cost way less $
