[10] Removal of brake piston Attach a pressured air nozzle to the flange (1-1) oil path for the parking brake, and inject compressed air to the parking brake cylinder chamber to raise the brake piston (1-15) and remove it. After removing the brake piston, remove the disk plates (1-13) and friction plates (1-14), and remove the O-rings (1-16) and (1-17) from the brake piston.

[9] Removal of O-ring, knock pin and spring Remove the O-rings (1-22) and (1-23), knock pins (1-19), and springs (1-18).
Cautions: When removing the brake piston, observe the following precautions. a. When injecting compressed air from the flange oil path for the parking brake, do not let any compressed air leak out. b. When injecting compressed air from the flange oil path for the parking brake, the brake piston may fly off if the pressure of the compressed air is high, and this may cause injury. For this reason, set the air pressure at 0.29 MPa or below, and hold down the brake piston while performing work so that it does not fly off.
