I want to make clear that I changed out three out of four of my calipers (ran out of money, the LF caliper was OK, but still, 18 years old...) with the Cardone rebuilts-not the same one three times. I tried them out tonight and they seem fine. I screwed up the parking brake adjustment, but, this was the first major brake job I've done in 20 years....

My brake fluid was like milk with rust in it (it isn't anymore-flushed it as best I could and put in some DOT4).
