Stopping Bike Disc Brake Squeal - Here's a GOOD DIY Technique you Probably Haven't Tried Yet! 

Who needs a bike bell when your brakes sound like that!!!

I've learned to modulate my brakes so that the squeel mimics geese, I can now lead a flock of geese pretty much anywhere I like.

This worked perfectly for me. I did everything just like the video. I feel like I have a new bike now. Thanks for sharing!

I wouldn't have believed it if I'd not tried it. but it works. I sounded like a fire truck riding down the road and had my kid laughing, but it worked.

This worked perfectly for me. Tried a lot of different methods to get rid of the squeak but this was the only one that worked. Definitely recommend doing this.

I might give this a try. Bought a second hand mtb recently, and I basically woke up the entire neighbourhood by simply braking.

Totally worked 100%!!! been riding 20+ years and never heard about this. My bike had it BAAAAAD! 5 times worse than this and it worked. Thank you so much this made my day. Subbed!!!!

Worked great, thanks. Since I'm a bit lazy, I took a piece of cardboard and cut a rounded slot to fit around the cassette to protect it from over-spray so I didn't have to remove the back tire. I also have enough De-Squeak to fix rotor squeals well into the next century.

Thanks! Your suggestion on how to stop bike squeal was excellent. Did it and after a few puffs on the bike the noise was a gone.

Great technique! I'm about to call the shop where I bought my bike then I saw your video. Thanks man! Thumbs up :)

Sweet, good to see this put into action Chris! Looking forward to more videos!

I tried it and now my disc brakes work perfectly.Very good video.

Good idea and one to keep in mind for troublesome squeaks. Maybe use a clean rag for cleaning rotors otherwise you could be introducing contaminates.

at 2:16 he runs over a goose.

I had a fouled rear rotor that I used all the other techniques on, but the squeak would always return soon after clearing up. This technique, while hard on my legs and troublesome to my neighbors ears, worked wonders. I will never try the other techniques again. Thanks for the solid advice. I had no risk as I had a spare rotor coming free from my bike manufacturer and new pads. Now I can leave them both on the shelf as spares for another time. You rock!!

Mate I tried your technique and it worked like a treat, just like your video. Thank you big time

This worked really well for me after the standard de-squeal methods all failed. Thanks!

Reporting back: I tried this method out, and it worked like a charm for about 300 miles. The front rim is finally starting to squeal again. I reapplied the spray-on stuff and the squeal is gone again. This method of desquealing works great in my opinion -- I'd tried tons of other methods (cleaning, readjusting, new pads, new rotors, etc etc) and none of them worked at all. I'm surprised this method isnt more widely recommended.

My brakes sounded exactly like that. I've tried cleaning the pads and discs with alcohol, but it didn't work. Found this video and tried your CRC method. Well - after about 3/4 mile screeching like a banshee, she settled down just like in the video, then.....nothing! This method worked a treat on my bike (Specialized Stumpjumper with Shimano hydraulic brakes). Thanks Chris!!!

Tried all the other tricks, finally came across this one and it worked 👍 plus got a good workout!

I tried this on my ebike brakes that sounded terrible. It worked just like the video. The bike shop I brought it too was not able to fix it at all, so I shared the video with them. THANKS

Thank u awesome just bought a specialized and keep going back now there's that squeak after a flat tire.

This has been my preferred method for years. Except I've been using Swiss Stop Disc Brake silencer instead. It's pretty expensive but works like a charm.

Shop was not open to get de squeak so just went to a quiet long hill and applied breaks. Worked !!!

I didn't want to spend the $16 for a can of De-Squeak on Amazon so I tried Ajax, applied with a sponge brush. I didn't have to remove the rim. I applied an Ajax paste (Ajax and water) on the rotor with the sponge brush, then followed your technique to remove the glaze. Worked like a champ. Ajax was 88 cents, the brush was about 50 cents. When I was done, the Ajax paste hosed right off. Both front and rear brakes worked better with no squeal.

This helped me so much, I worked on my bike for a whole day until I saw this video

My brake squeal was driving me nuts. This totally worked for me. Thanks!

It is probably a good idea to check and clean your pads too...

This thing saved my life

I watched a bunch of ways but yours worked the best

Yep, that shit totally works! Fixed it fast! Didn't even have to ride around annoying everyone with the squeaking very long. thanks Clydesdale Chris!

I had the same problem with my front disc brake and I sprayed ready wrench on it. It worked for a little bit. I will definitely do this trick next time.

I have no idea how you figured this out but I don’t give a damn cause it worked thanks!

This worked as advertised. Thanks! Pay no attention to the haters...

Thank you so much this video helped me resolve my squealing. I'm in the U.K so I got a different brand but did what you said after applying the product, really need to heat it up by breaking half way until eventually the terrible noise disappears. Thank you thank you thank you!!!!

how does he only 400 subscribers, i was expecting like 75,000 lol, I hope he continues this channel and it grows

It's a good exercise as well. Thanks for your video.

I left my bike at a workshop for bicycle repairs and they could not solve the screeching sound. Followed up on some other peoples advice to apply ceramic paste (non metallic paste, heat resistant) between the braking pads rear side to hydraulic piston. Still did not solve my issue. Didnt try the old trick to simply heat up the brakes as this dude did though, I say it is worth a shot! Will have to wait though until the weekend, otherwise my neighbours will go crazy at me...

Okay, watched this vid on Sunday, bought the stuff today and I was about to call bullshit after the squealing got louder and louder and the neighbors came out to see what ruckus was, so I stopped to talk and explain and when I went to show them how my brakes squealed….well they were completely silent…..neighbors just think I am wierd now 🤪but my brakes are quiet so thank you!

Omg I’ve been looking for a Solution for this THANK YOU

I'd post a pic but duuuuuude.. it works! Tried it on my 2018 Specialized Rockhopper Expert. Thank you sir. Subscribed. Also holy crap that was a workout and also feel for my neighbors listening to that garbage. Lol.

Tried your technique on my excessively squeaky Scott road bike. It worked great! My local auto parts store didn't have the CRC spray, but the alternate compound spray they had appeared to work well. Thanks 🙏

THANKS SOOO MUCH!!! I tried everything before this but it actually worked. Although I did feel like an idiot riding through my neighborhood.

Totally worked! Thanks for putting up this video

Recently had this problem while riding. Grabbed some wet sand/small gravel from a creek, smeered it on the rotor, slammed the brakes a few times and voila. So far so good

Some good info man...thankfully my hydro brakes have been great to me lol maybe its becuase its resin pads idk but so far so good on my rockhopper 29er

Thank you for the video demonstration on how to fix the brake rotor squeal. I looked online for the CRC De-Squeak product. Found it for $23.99 at my local Napa Canada store in my town. Thank you again!

I always use alcohol basically same as here in this video , Then I just apply the brake and push the bike a few times giving it full rotation until the squeak stops, alcohol leaves no residue . I am always leary about using automotive products on my bike , lol you scared me with that brake cleaner for a second ... My method works every time and without extra chemicals (unless the pads are contaminated or worn right out). Cool vid , this method seemed effective and relatively safe in this case.

Was skeptical but desperate enough to try this. Squealing is now gone and I got a good workout.

Great video, keep up the good work!

Another method I use is undo the caliper bolts not the adapter ones so it's losse pull brake leaver so it centres the caliper tighten back up while brake is still applied then release brake and perfectly centred no rubbing or squeaking and even brake pressure dunno if it's any help but I find it works well for me but good video but I learned something new 👍

Use a CLEAN rag not an oily used one

literally the only video on youtube that i didnt mind watching the 3 minute add halfway through the video

Those are sweet reflectors on the first bike's wheels! Really hard core.

Holy apple pie on a sunday- it worked! Brake Squeal Treatment (Squel medic) essentially the same product - it worked!

Hey Chris! Thanks for the video! Had the same problem, but it looks like mine was due to contaminated pads...my rotors were black from the oil 🙈 rotor also looks like it is damaged. I traced the origin of this back to transporting my bike on the back of my car in the rain - oil and dirt from the road must have seeped into the pads. They were brand new...so we learn! Good tips in your clip man!

Thank you for great video! I don't know that was very irritating, lol. I like alcohol and sandpaper trick better I seen on different channel. He had no squeak.

Work well. Finally no squeak. Hopefully it will stay quiet ! Thanks

Realigning the caliper can't be understated. It's as simple as unbolting it a little, squeezing the brake lever and tightening it down while squeezing. Also a mountain biking trick is to use sand or mud as the grinding compound...which is what's in that can. Update: Looking at the prices of that CRC stuff I got to thinking that valve grinding/lapping compound will work just as well if not better and less messy than mud/sand. It does work. Permatex Valve grinding compound - 5 bucks and you can water it down. slap on a light coat and wipe off the rotor when done riding(grinding). Still a lot easier than pulling the pads and hand sanding them and the rotors individually. Cheers.

Hey buddy thanks for the video I’m thinking of getting some off that brake spray I found it on Amazon on my phone while I was watching this on my iPad. I have a E-bike Stealth Bomber with a 8000kw motor. This may help bed my brakes easier and quicker. Thanks again for the video buddy.

First off: thanks for sharing the video. Do you know if this technique applies to organic brake pads?

Thank you Sir, great video.

I changed to 4 pot brakes on my Silverback Stratos AL5, came with cheap semi pads, squealed like a cat under a tyre, I took off the pads and rotors, took 1200 grit sand paper, dish washing liquid.. and scrubbed till I could see the red on both pads and rotors of my blood after my finger nails were scrubbed off. Let the pads and rotors air dry, and put it back, made sure everything was aligned properly and took for ride.. hasn't made a sound since.. I do believe the cheap crap pads make huge difference.. so new pads definitely in the future,as here in South Africa we don't have that 'De-Squel'

It worked! I had some brake cleaner at home, didn't know the brand, and just happened to be CRC!

Great video and fresh approach to brake squeal. I noticed your bike mechanic stand, I'm looking for a new one which one do you have and are you happy with it? I currently use a park tools head-mounted to a 2 x 6 in a large vise on my workbench works great but I'm thinking of freestanding stand will work better for me

thanks boss worked out great on my bike thought i would have to go spend money

This worked quite well. Very pleased with the results. Much appreciated good sir!!. Warning put ear plugs in b4 attempting this method. I live in the country so wasn't an issue with neighbors. And boy what a good workout it became.

The squeeling problem comes from the glazed discs. The de-squeel compound acts to de-glaze de discs.

It is good to know and thanks for the tips.

Nicely done...

Another temporary fix(on trail side will last 10 mim max) use water, I know it sounds counter intuitive but sometimes the water will create an insolating layer to help absorb the vibrations. I haven’t gotten Around to doing mine so this works temporally just to get you home with hearing intact.

Nice tip! Thanks.

Must try this | Me Brakes squeal loik a gud un . Hope this works. Thanks for the tip

Good to know info!

Thats why i cant track stand my bike so much because of my brakes, its squeal when i press the Brake Lever. I should try this tomorrow morning. How many Minutes after the sound gone?

Maybe the clearning part helped a bit, but I think keeping brakes on while biking is the thing that grinds the shit away and makes it clean and quiet. Thanks anyways, now I know what to do !

i have seen this done in a similar fashion but instead of spraying the full break rotor they spray only the small pads that grip the rotor just two quick sprays on the small pads then do the same pedal and break at the same time and done but there wasnt any need to waste so much spray for thr rotor parts.....none the less both worked well ;-)

Wow it's work. Thanks.

I have never tried this, interesting. So far I just used Muc off dry degreaser to clean rotors, my local automotive shop sells CRC, maybe they got this, but I sand my rotors down with sandpaper, only time I had squeal brakes was when the Shimano M615 & m396 leaked, due to worn seals & oil spills on the road, by degreaser always did the job, but oil, braking fluid will result in glazing, and change of color due to extreme heat.

The WORST thing you can do to ruin your disk brakes is to put any lubricant on the disk, like oil or grease will make the discs too slippery and will result in the pads not getting enough grip. Not only that, some lubricants are flammable lol. Good job sir, this is a very good idea.,I like you video.

The reason brakes start to squeal and less stopping power is from glazing of the rotor and pads. What you're doing with this method is removing the glazing and like you said bedding them to each other. Good tip. Oh another reason brakes squeal and loose power quickly is the fluid gets hot and in some cases can boil breaking down and introducing bubbles into your system so I would bleed the brakes getting all of the old fluid out and replaced with the proper fluid for the system you have.

Thank you for that, Any cons to these method ? like Any reduction in stopping power , any damage to the piston/caliper ?

I have always thought about Mountainbike wheels that have a thin, hard, smooth middle (similar to a roadbike tire) but just in the middle so you can reach higher speeds on the streets easier and sell them if they are worn down to people that just want normal offroad tires.

Thanks.... I'll try

Hey, I had this problem twice. I washed the rotor, with dish soap, and on the brake pads I applied sand paper, to eliminate the contaminated layer. Then you need I brake a few times very hard from about 35kmh. But the brakes will come to perfect normal in about 20 km of riding on streets and braking only with front. Like so the comment will come in tranding

Thanks man it worked ❤️❤️

You can also spray that stuff onto a paint brush and paint it onto the rotor. Less over spray.

I heard people at my trail say doing this brake workout without the de-squeal actually works wonders too. Wonder how much better the anti squeal stuff works, or if it works at all?

Cool it helped thanks! 👍

Can you give some alternatives of the de squeak product and can loopwipe do this job

Another tip is to check that the disc is not mounted the wrong way. Mine was in reverse and made a lot of noise. By inspecting it it was clear that the spokes in the disc would collapse rather than hold during high stress. By turning it around the bike was silent again and safer.

I've used this product; CRC De-Squeak on my bike. Fixes the squeak temporarily meaning the noise returns. Also the overspray doesn't clean up with just a rag. It took mineral spirits since the stuff is like paint.

Thanks! Subbed.

Tried this and it worked beautifully. 50 kms in and no squeaks. Does anyone know how long it lasts (how long until it needs to be re-applied)? Interestingly I have a custom built rear wheel that has an upgraded, metal compatible rotor. The experience in running in (cycling with brake applied) was considerably different with the upgraded rotor. The resin pad only front rotor didn't stop squealing nearly as quickly as the upgraded rotor on the rear. Age of the rotor? Material difference? Resin pads were, front and rear, less than 1 month old with 550 kms on them. Anyway, bravo Chris. Excellent solution.

After a hard breaking from nerly hitting 2 young childs my front break disk is now squeeling. I hope this work

Thank you very much this helped a lot!

Awesome! Thanks!!

Iv found cleaning the disc and pads with disc cleaner then lightly sanding them both also works. Never heard of disc squeak spray before.....

Nice pickup truck!

All I had to do was blowtorch the rotor dry and then I braked hard as I pedaled hard down a steep hill. Work perfectly now.
