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.
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
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.
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.
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!!!
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
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 😃.
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
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!
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.
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
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
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.
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
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 😎🤙🏼
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
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.
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👍
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
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.
@@GCPerformance18 it is interesthing that , this squealing happens most of the time with shimano setup, never experienced that with tektro or any other brands.
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.
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.
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.
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
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
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.
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
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.
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!
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.
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?
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
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!
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
@@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.
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
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.
@@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.
Just bought my first disc brake bike and WOW, what a disappointment that loud squeel was. This makes me hopeful. My new bike has less than 200 miles on it 🙉
Did any lube get on the discs? Or did you ride in the rain? Sometimes if you get caught in the rain, the water can wash all the oils and stuff from cars from the middle of the road to the bike lanes
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 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.
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
