I swapped pads and rotors last week and my calipers are in pretty rough shape. In its previous life, car spent a couple of years on the blocks after serious mileage was put onto it. Calipers have a tremendous buildup of brake dust that fused all over the inside of caliper housing. I had to grind down the housing to drop pads in, and they are still binding. Instead of further grinding down the calipers, I am thinking of just replacing them. Does anyone have a set in decent condition for sale? Since I just got brand OEM new rotors, upgrading is not an option. Thanks!
