I think I may have fixed the calipers just by pulling the pistons out and reinstalling them.
However I’m super annoyed at the parking brakes, I’m trying to use my stock drum brake cables and hardware like a thread in the tech section says and there’s just no way it will work. First off the driver side is too short and bends at a horrible angle around the caliper and just barely fits into the slot in the bracket on the leaf spring bolt.
Second the passenger side is too short unless I also run it at the most direct route which is touching the gas tank and going to make contact with the leaf springs.
So WTF! I’m really annoyed at not having a parking brake but I have no idea how to make these work. The pictures in all the tech page write ups suck.
