So I got my bike used and it has an off brand mechanical rear disc brake. The brake has floating pads (magnetic) and I recently replaced them and Bed them in properly. Lately though When not locking up the wheel, I get a tremendous squeal. I took off the rotor and pads and sanded/ cleaned them and re bed them in and the same problem occurred. I think it might be a vibration problem as the caliper even when fully tightened down can move from side to side quite a bit and as I mentioned the pads are floating. Does this sound like the problem? My avid brakes up front don't have the same issue and don't have any side to side play. Should I just replace them? Thanks! Oh and the pads are not contaminated, they haven't gotten any oil or anything on them.
