Am stuck...three quick questions:
- one of the two front caliper pistons (other popped out immediately with compressed air) is now retracked, frozen in place, and will not budge/loosen using compressed air nor using manually trying to turn piston out...any ideas?
- side cap on front caliper also frozen and will not unscrew...a steel bar, inserted in slot with caliper in vice, bent and cap didn't move a mm...any ideas?
- will removing the four bolts (1 in pic) at the base of the wheel hub allow me to remove the brake disc, or do I need to also remove other bolts on the inside of the disc?
