I have a shimano br-m446 installed in my MTB, i recently replaced it with new pads, my problem is that it is squealing so bad, with a mild to moderate vibration during braking in downhills. and it's really really annoying.
I haven't placed anything on them, i clean my rotors with water and laundry detergent i don't know if that causes the problem.
if so what should i do?
thanks.
