Brake disc rubbing pads/calliper

paulneenan76 · April 2013

Over the last few rides the rear disc rotor is rubbing the pads in the calliper. I was thinking the disc had warped but I've taken the rear wheel out, re-seated it, and it seems true to me. I know these will rub from time to time but should self adjust? It's definitely touching the pad though - any thoughts?

Brake is working pretty well considering.

Push the pistons home and reset the pads.

Thanks Nicklouse - what's the best way if doing this?

Remove wheel, push pistons/pads back with a big screwdriver (carefully so you don't wreck them - stick an old pair of pads in if you have some), replace wheel, squeeze lever a few times until they work.

Thanks. That's sorted what to do tomorrow morning - lets hope I'm not still faffing by the time the roast is cooked

It should take about five minutes. Or less.

When you pop the pistons back, sometimes I give the lever a gentle squeeze to check that both pistons are pushing the pads equally. Sometimes one of the pistons can stick which is a pain!
