Front Caliper (BREMBO): Disassembly

  1. Remove pads, and clean exterior surfaces.
  2. Use air pressure to force piston from cylinder. Insert brake piston resetting tools (b) and (c) in piston. See Fig 1 . Place a wooden board (a) into the recess of the caliper housing to catch the pistons so they are not damaged. Only one piston can be pressed out at a time. Hold the other piston securely in brake caliper housing using piston resetting tool.
