I have a set of Deore 525 Hydraulic discs but use XT rotors. The back rotor squeals like a banshee only when going downhill but otherwise is silent. There is no difference in braking performance, just a loud noise.
The rotor is clean and the pads are new. It's just the back rotor.
Any Ideas about what's causing the noise and what can I do about it?
Any help appreciated.
