1. Correct axle alignment.
2. Return hole in master cylinder open and clear.
3. Remove caliper pistons, clean and lube seals and pistons.
4. Lube caliper slide pins.
Return hole is open and clear. Replaced pads and lubed slide pins, Don' really want to remove pistons (if it's not broke don't fix it) and not sure on the alignment on the axle. Is there a way to check?
