auto mechanic told us the rear brakes need replacement. I inspected the rear brake pads and found 3 out of 4 were in excellent condition. The forth was ground down to the metal. I assumed that the slipper needed cleaning. After removing the caliper, I inspected the slipper, the caliper locating bolts, and caliper rubber bushings. All were in excellent condition. The metal under the slipper was a little rough but I did not think it would affect the brake pad movement. I wire brushed the area under the slipper and then installed the slipper…
I measured the disc run-out and it was within specifications but I could see that the disc that had been in contact with the metal in the brake pad needed to be resurfaced. I removed the rear brake disk and discovered that the parking brake shoe linings were in very bad condition. I took the discs to the auto parts store and they could not turn them [0.54 inches on my disc; minimum 0.51 inches] Ford says to resurface the disc on the car with a special milling machine and not to turn the disc off the car on a lathe. So I bought new rear discs.
Do you think I should replace the caliper on the side where the brake pad metal has been in contact with the disc? Would a faulty caliper fail to release from contact with the disc when the brake pedal was released?
