Hi All

I have been having annoying squeeling rear brakes on Shimano XT's when applying them. I had cleaned the rotors with Isopropyl. Roughed up the pads which worked for about 1 ride. I have since replaced these as they were sintered with the correct approved ones and this stopped for several rides, but has come back again. There is no contamination on them on a visual inspection that i can see. This is currently doing my head in. Any other ideas out there please on what I can try next will be gratefully recieved

    Bed the pads in properly, and don't drag the brake.

    What sort of squeal? A high pitched squeal at constant frequency and only the volume changing then it's a resonance, sintered pads will be worst, kevlar or organic better, you could try and different disc and make sure all the bolts are tight.

    If it's more a moan then it could be some contamination somewhere.
