REAR BRAKE MASTER CYLINDER
Removal
1. Drain the brake fluid from the rear brakes as de-
scribed in this chapter.
NOTE
The master cylinder can be removed
while the brake pedal/footrest assem
bly is installed on the motorcycle.
However, this is a very time consum
ing process. The master cylinder
parts are more easily accessible if the
brake pedal/footrest is removed first.
2. Remove the brake pedal/footrest assembly as
described in this chapter.
3. Remove the cotter pin (A, Figure 59) and
washer. Pull the clevis pin (B, Figure 59) from the
master cylinder clevis.
4. Separate the master cylinder clevis (A, Figure
60) from the brake lever (B). Remove the master
cylinder assembly and its bracket from the brake
pedal/footrest assembly.
5. Remove the snap ring (A, Figure 61) and pull
the reservoir hose fitting (B) from the port on the
master cylinder. Discard the fitting O-ring. A new
one must be installed during assembly.
Installation
1. Install a new O-ring onto the reservoir hose fit-
ting and insert the fitting (B, Figure 61) into the
master cylinder port.
2. Secure the fitting in place with the snap ring (A,
Figure 61). The snap ring must be completely
seated within the groove in the port.
3. Install the brake master cylinder clevis (A, Fig-
ure 60) onto the brake lever (B).
4. Secure it in place with the clevis pin (B, Figure
59).
