For some days now I am observing the decreasing performance of my disc brakes on my MTB. Additionally, braking is extremely loud (squeaking). I don't think I have oil or fatty substances on the discs. Still I can't exclude that.
- So what do you think is the problem and how can I solve it?
I would guess I have to change the brakeshoes but I am not sure.
- How can I check the actual problem without wasting time/money?
- If I have to apply new brakeshoes, how is this done safely?
My brakes are hydraulic: Shimano Deore BR-M596.
