Disc Caliper - BENDIX Sliding Caliper: Disassembly

1. Wipe caliper clean around inlet port and remove plug. Drain fluid from caliper housing. Place caliper assembly on bench (piston side up).
2. Place several shop towels between piston and outer legs of caliper housing. Carefully apply low-pressure air at caliper inlet port until piston comes out of caliper housing.
   WARNING: DO NOT  attempt to catch or protect piston with fingers while applying compressed air. Injury may result. Always use eye protection when performing this step.
3. If piston is seized, lightly tap around end of piston with soft-faced hammer. DO NOT  attempt to catch piston by hand, since it may pop out of caliper with some force.
