and component parts to prevent damage and ease of handling
during reassembly.
1. Install new O-ring on the inside and outside of the packing gland and on the outside of the piston.
(When installing teflon O-ring on piston. it is recommended that it be installed with the use of a cone placed
against the piston. The cone may be constructed of plastic or metal with dimensions shown in Figure 32-13.)
2. To assemble the piston rod assembly, install on the rod. in order. the roll pins. return spring retainer
washer. retaining spring, packing gland with O-rings. seal. piston with O-ring. spring and retainer bushing.
Secure these pieces with snap ring on the end of the rod.
3. Insert the piston rod assembly in the housing and secure packing gland with snap ring.
4. Install the cylinder. (Refer to Installation of Brake Master Cylinder.)
INSTALLATION OF BRAKE MASTER CYLINDER (HAND BRAKE). (Refer to Figure 32-12.)
