i've had new black diamond discs and pads put on the back but because the brake pressure valve needs altering it is putting to much braking force on the rear brakes and now there squealing like the pads are worn out. will this stop when i alter the brake pressure or do i need new pads again?

did you put copper slip on the back of the pads

As j7aoc says, you will need to ensure there is some copper grease on the back and side of the pads, NOT on the front of the pad obviously.

If they have anti-squeal pads on the pads then you only need some copper grease on the sides.

i never new you needed to put copper grease on the back and sides of pads? ive never fitted any before and have always got mechanics to do it for me cuz i dont know what im doing and dont want the brakes going on me if summat goes wrong. i dont know if the bloke put copper grease i, i will ask him as hes my missus uncle. otherwise i just need to take them off and grease them up and it will be fine?

cheers

i think they're black diamond predator pads.

I've never really thought about it, but I think the squealling is down to them vibrating at some daft speed probably which the grease stops them doing.

ok then, well i'll get the missus's uncle to take them back off and grease them up then cuz dont think he's done that.

thanks guys!
