I've always been able to hear a slight hiss from the pads when I rotate both the back and front wheels. .
That all sounds goodBut I still dont get it, because the pistons go in depending on how thick your pads are. So thicker pads wont be pressing on the disk any more than thin ones would.isnt it ??
. And don't forget latent pressure in the system.
The piston can only retract so far
Quote The piston can only retract so farSo you are saying that the pads are so thick that they are pressing on the caliper and not the piston when not under brake
