Glad you got it fixed. Just want to add that having had the same problem at times, cleaning the rotors like you did as a start. Second, remove the wheel and the pads and push both pistons out with pads in using a flat headed screwdriver. Put the pads back on. Put the wheel back on. slacken off the brake calliper, quite loose, a good 1.5 turns away from torque.. Clamp the brake lever and tighten equally both bolts whilst holding the brake lever. Let go of the brake lever. Clamp the brake lever, fully tighten to torque. Never failed me yet. Cheers.
That doesn't always guarantee that both pistons will travel the same distance- you may have one that is "stickier" than the other resulting in the caliper not being centred over the rotor. I worked in an outdoors centre with 60 bikes and the kids always dragged and glazed the pads, some bikes were so past it the calipers sometimes leaked and what I found was that contaminated pads- from oil, mist spray from aerosols(ie WD40-instructors trying to "help" by working on the bikes behind my back!!), mineral oil etc all went in the bin...the time and effort trying to save them wasn't worth it and rarely worked!!! With rotors you can always carefully apply a flame from a propane torch to the brake surface(don't discolour it!), this will burn off any impurities that the other methods don't fully resolve. FWIW- Personally I've never had squealing brakes on my bikes, and I stick with resin pads anyway!
@@LivandTrekGoCycling Sintered ones are noisier, but take a while to heat up and are the strongest braking power (and you get a compound that's "semi metallic" (half'n'half) IIRC, the rotors may advise what pads you can use anyway- sintered etc generally on DH/MTB where brake fade would happen with resin pads under heavy use....Once bedded in and working remember to never touch the rotors with bare hands and watch for aerosol contamination!!
Oh..yes, I've learnt the hard way about touching rotors with bare skin. I even make sure I remove the rotor from the back wheel or cover it now when I put the chain through my parktool degreaser bath...so flying dirty oil doesn't land on the rotor. Once bitten...twice shy 😉
Great video and glad you fixed the problem! Have you found that the squealing has returned over time and/or riding through wet/dirty conditions? Or have the brakes remained quiet over the long term? I'm wondering if the abrasive material in the paste wears out the discs and pads faster, leading to earlier replacement. Cheers!
@ivanyhtang Hi, thanks for commenting. The bike was only ridden a couple of times after that and the squeel didn't return but the bike was put away for winter and hasn't been ridden since. I think any pad or disk wear caused by thr paste would be minimal and much would be removed during a wash after the application process is finished. Glad you enjoyed the video.
Hi Kevin, thanks for commenting. Whilst the tub is a small 3 oz size...only a small amount of paste was needed to cover two rotors of one bike. I didn't need much at all so I'm fairly happy that you get at least 20 uses out of a tub..maybe a little more. As a home user and not a professional mechanic...I'd bet the tub contents would last for longer than I'd actually need it.
@@DirkSachse Thanks for watching and commenting. I'm not sure if it's a ceramic paste although I wouldn't be surprised if the principals behind how it works are similar to other automotive products. I know similar products exist but I've never tried them. I just know, even from watching other reviews on TH-cam...this stuff works 🚴👍
Let me know what tips you have for dealing with noisy disk brakes. Thanks 😊

So...resin pads have a benefit of reduced squealing then?

It's expensive but, how many applications would you get from that wee tub?

What do you think that stuff is? It looks like ceramic paste which is available in the automotive industry for squeaky brakes.
