Re: New Brakes..squeal In Reverse
Copperslip on the back of the pads is correct - the suggestion of "greasing" them certainly intended this, I think. Don't put grease on the friction material.
If they are new and squeal in one direction it may also be trapped dust. If you can get an airline in you might clear it without dispmantling but use normal H&S measures to cover eyes and nose.
