Newbie321 Posted July 30, 2019 Posted July 30, 2019 Hi Anyone know if there are shops that do brake mount facing?Ever since I've bought my new bike the rear brake vibrates the entire frame. The shop I bought it from cleaned and sanded the disc, realigned the calipers etc. I've cleaned it myself a couple of times, adjusted everything even took my front Rotor and Pads and installed it on the rear, which helped a lot but there where still some vibration. Now I'm left to believe that its the mounting or maybe even the brakes themselves that are not mounting evenly resulting in uneven contact and vibration. It really is a pain to mount my rear brake as any of the usual tricks like pulling the brake while tightening does not align everything correctly.

Surely if it was a new bike this sounds like a warranty issue. I would make it the shops problem.
madmarc Posted July 30, 2019 Posted July 30, 2019 You need to check that both pistons are moving together, sometimes only one piston moves or moves more than the other when applying brakes. Take the brake pads out and carefully pump the brake to make sure both are moving. If only one moves then hold it in with a tyre lever and pump the brake a bit more until the stuck piston moves - take an ear bud with some cleaning fluid and clean the part of the piston exposed then push them back. Just don't pump the brake too much or you will push the piston out completely needing a rebleed. Also measure your brake pads and make sure they the same thickness, after lining up the caliper have look to see which pad is rubbing on the rotor - then turn the pads around and re-align and check if the rubbing pad is on the opposite side now. Re-facing the mounts is an option but make sure whoever doing it knows what they doing, too much and the caliper will rub on the rotor - needs to be done very gently just to remove the paint and a light skim on the face
Butterbean Posted July 30, 2019 Posted July 30, 2019 I don't know if it's the problem, but if anyone can fix it it will be Stoke...
Mr. G Posted July 30, 2019 Posted July 30, 2019 What type of brakes are they, surely you can claim under warranty?
Newbie321 Posted July 30, 2019 Author Posted July 30, 2019 doh... I'm in Cape Town. If cleaned the calipers and made sure they coming out evenly. The reason I believe it's the facing is because when tightening the brake it tries its best to tilt to one side. I'll take it back and see what they can do.

( ok, i see google says its this) Are you using the appropriate washers ?
David Marshall Posted July 30, 2019 Posted July 30, 2019 If you have a through axle wheel I doubt that you will find anyone with a facing tool that will work. Forks and frames are now made far more accurately then a few years back so the tools in the trade will only work on skewer frames (unless someone has invested in a new one). If you can align the calipers correctly it is not likely to need facing. The only frame that I have had to face was one where the bike was ridden with the caliper loose and it wore into the frame.
droo Posted July 31, 2019 Posted July 31, 2019 I've got a tool that will work if that turns out to be the issue.
