Front Brake Caliper - Disassembly

Warning - Brakes - Fingers inside caliper openings

warning
To prevent injury, never place fingers or hands inside the caliper opening when removing the pistons. Always wear eye, hand and face protection when using compressed air. Eye, face and skin damage will result from direct contact with compressed air.
  1. Separate the caliper and mounting bracket.
  2. Cover the brake caliper opening with a clean, heavy cloth and, using either compressed air or by reconnecting the master cylinder and pumping the brake lever, eject both pistons from the caliper at the same time.
    3. Front Caliper disassembly

    1. Dust seals

    2. Piston seals

    3. Pistons

    warning
    Ensure the seal grooves in the caliper bores are not damaged during the removal of the seals. Damage to the seal grooves may allow brake fluid to leak past the seals resulting in a dangerous riding condition leading to loss of motorcycle control and an accident.
  3. Extract the dust seals and piston seals, taking care not to damage the brake caliper bores.
  4. Check the pistons, caliper and mounting bracket for signs of damage, paying particular attention to the caliper bores and pistons. If damage is present, renew the worn component or the complete caliper assembly.
