ABSTRACT:
The method includes moving a piston and a force transmitting element connected to the piston to a locking position. The piston and force transmission elements are locked in the locking position which preferably is displaced from the brake released position. Preferably, the piston is locked to the housing and the force transmission elements to a brake beam. A portion of the cylinder surrounding the piston is removed from the housing which is connected to the brake beam or truck and the packing cup is replaced. The cylinder portion is then replaced on the housing and the piston and the force transmission elements are unlocked and the piston and the force transmission elements are allowed to return to their released position.
