Review on ACDelco 18K281X Professional Caliper Hardware by Dwayne Shavers

AWESOME! My brakes are silent again. I upgraded my brakes to ZR-1 size. My search for brake pins that I now know should be replaced with every set of pads kept coming back to this set. There are different length pins for different calipers. These pins have 2 sets of slotted ends for different sizes. And they come with these 4 little springs that keep the pads pressed tight. I hit bumps in complete silence.
