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!!!!

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 🙏🏻

This video is very timely! I’ve noticed the same noise for my bike. Checking my shopping cart out now. Thanks for sharing this!

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.

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.

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!!!

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👍

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

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 😃.

The sound effects are great. They are on par with your usual special visual effects.

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

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 👍

GC performance gets the 2021 award for best intros

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 😎🤙🏼

interesting, im gonna need to try this out. thanks mr GC

This weird noise😂😂I love this channel

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...

Ive just ordered a tub from the only retailer I could find selling it in the UK. Fingers crossed for when it arrives!

“Both hands on the steering wheel” brilliant! 😆

The sound impression is spot on!🤣

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.

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.

thank you for your knowledge and experience

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

have you tried copper grease on the back of your break pads,that works too.

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?

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!

Thanks for this info! Do you think that the product will work with Resin Pads as well as Metallic Pads?

The ultimate solution and a gamechanger seems to be just going back to rim brakes.

this will be great especially since l03a are out of stock everywhereeee

Thank you GC 🙏🏽

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!

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.

Got mine thanks gc performance

🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣 the brake stop at the beginning… oh soooo familiar… 😆😆😆🍻

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

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

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.

Swisstop makes disc brake silencer also. It works like a charm.

Love the sound effects lol

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?

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!

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.

Thank you.

Use isopropyl alcohol on the rotors and pads when you clean your bike after each ride.

Gc any new options that you have been using? Can’t find this anywhere

Very cool tip.

You should have done a "B4 & after" segment of the video. Looks like pretty decent stuff, NTL! Just wondering if there's a downside to using this stuff such as "using too much could wear out the pads/rotars", etc...

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.

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.

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.

This thing does not seem to be available anywhere anymore. Is there an alternative?

Have you tried muc-off's disk brake cleaner?

i wonder if toothpaste would work - i have this issue on my bike at the moment but dont want to wait for shipping

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!

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?

GCN is going to be like “should we just hire this guy?”

Run Paper towrel on rotors both sides and get new paper towel dab into acetone and clean.. am its cheap

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.

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.

Where can I buy this? Looks like the place you listed doesn’t sell it anymore 😢

This is awesome but dam I miss the rim brake days.😑

I now need you to do the donkey brake squealing sound on every video. 😂

That looks like sl6 pro. That bike in person looks sick. Is that your personal bike?

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.

Any suggestions on where to get this? Seems sold out everywhere as of 6/2023. Also any alternatives that work?

thank you i will definitely buy some of this stuff 😊

Is this only for contaminated pads/rotors? My front brake always gets glazed, and squeals.

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.

I just placed an order, this might maintain my sanity.

Thanks for your help and great information

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

Sending the pads and rotors, cleaning them with alcohol and rebeding the brakes, does the trick every time. Also sram AXS brakes never squeal👍

Can this be used on electric scooter disc brakes?

Just what I need, just can't get it in the UK

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.

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.

@6:14 better than actual squeal

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...

What do you charge at your shop for that service?

It’s a cool 12 degrees here in MI

What width handlebars do you use?

Disc brakes are “efficient”? Care to expand on that one?

Can’t seem to find this for delivery in the uk without import from US at megabucks 😡😢

Videos like this restore faith on humanity. Still not a big fan of disc breaks though 😁.

I found that rubbing some dirt / mud on the rotor achieves the same result.

Whenever I have brake squeaking issues I wipe the rotors with alcohol. Problem seems to go away.

how long does the fix last? , does the squeeling comeback eventually?

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

use a head or chest mount for your video camera, then do a proper 2 hands brake test.

Chain lube sling causes these squeaky brakes. Disc not as bad as rim brakes though.

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 can't find the product Any other place that carries it?

"A cool 79 degrees " 😂🤣 where i live that would be scorching hot .

The product is no longer available anywhere :/ anyone know what happened to it?

that intro ahah!!

Local bike shop couldn't fix wife's disc brake noise. Many trips to the shops and we have up.

swiss stop make a brake silencer that does exactly that just in aerosol form

Oh man it pisses me off that shimano still doesn't provide a 160mm bracket/adapter with the new groupset for the rear brakes
