Lewyza Posted October 9, 2012 Share Hi all, I took my 29er Silverback MTB out for the 3rd time only after it was standing for awhile an when ever I brake hard, it would make a noise. What do I need to do to remove the noise when braking? The bike is still new, was standing for about a month before its next ride and all of a sudden starting making the braking noise.

Dirtbreath Posted October 9, 2012 Share Oil contamination, dust, sticky cylinder not returning. Is the pressure still there. Which brakes? Link to comment Share on other sites More sharing options...
Lord Catapult Posted October 10, 2012 Share I have to same problem with my Ghost, it has Magura MT2 brakes, I tried anything short of replacing the pads and rotor but it still persists. Link to comment Share on other sites More sharing options...
Dirtbreath Posted October 10, 2012 Share If its not too wet and your brake bleed is not a problem and everything is clean do a ride on organic pads. The sintered pads are very unforgiving and react badly to dust. Edited October 10, 2012 by Dirtbreath Link to comment Share on other sites More sharing options...
Mojoman Posted October 10, 2012 Share I have to same problem with my Ghost, it has Magura MT2 brakes, I tried anything short of replacing the pads and rotor but it still persists.Same problem with my ghost and elixir 3 brakes. SRAM replaced pads with organic ones and updated my rotors to HS1 type. Did a 30km ride yesterday, slightly better, no so much squeal now. It appears that certain bikes and certain brakes are not a good match. But try scuffing up the brake pads and rotors with some sandpaper (lightly!) and bed them in again. I have read that guys have done everything from placing fishing weights on the caliper to trying expanding foam in the frame! Link to comment Share on other sites More sharing options...
Bianchi Posted October 10, 2012 Share Ive got the same problem with my Mahura Mt4's. I'm used to it now.The best solution, or temp in my case, was to sand it down, clean it with 95% surgical spirits (ethanol) and then to bed them again.Check around here for the best way to do that though.

Pieter1 Posted October 10, 2012 Share What worked for me was to put sunlight on my rotors, ride and brake hard a couple of times. Rinse and its fine. Link to comment Share on other sites More sharing options...
Mojoman Posted October 10, 2012 Share Out of interest, the guys with the braking noise issues:Is it on your front brake with post mount? Link to comment Share on other sites More sharing options...
Bianchi Posted October 10, 2012 Share Out of interest, the guys with the braking noise issues:Is it on your front brake with post mount?In my case, both brakes. At maximum braking it's not too bad, but at "slow down braking" it sounds like a train. Link to comment Share on other sites More sharing options...
Lewyza Posted October 10, 2012 Share Thanx for the info this far. It's the front and back brakes and only when I Break hard does it make the noise. Maybe I should get it out more in the sun, don't no but it was only my 3rd ride. Maybe cause after a ride I would wash and hose the bike down then put it in its store room Link to comment Share on other sites More sharing options...

merc1 Posted October 11, 2012 Share Best method is to get motorex disc cleanerRemove pads and spray rotors and callipers this will remove all dust and oilsIf noise still continues remove pads and dose them with mentolated sprit then use a lighter and light Them up. This burns off all the oil . If brakes are still noisy replace pads with new ones Link to comment Share on other sites More sharing options...
