6. Place the brake caliper assembly into position and
secure with new "patch-lock" cap screws. Tighten
the caliper to 20 ft-lb.
7. Place a new crush washer on each side of the brake hose
fitting and install it on the caliper. Tighten to 20 ft-lb.
8. Fill the reservoir; then bleed the brake system (see
Periodic Maintenance section).
! WARNING
Never use brake fluid from an open container or reuse
brake fluid. Moisture-contaminated brake fluid could
cause vapor build-up (expansion) during hard braking
resulting in greatly increased stopping distance or loss
of control leading to injury or death.
9. Install the wheel. Tighten in 20 ft-lb increments to 80
ft-lb.
10. Remove the vehicle from the support stand and ver-
ify brake operation.
MASTER CYLINDER ASSEMBLY
NOTE: The master cylinder is a non-serviceable
component; it must be replaced as an assembly.
Removing
1. Slide a piece of flexible tubing over one of the wheel
bleeder valves and direct the other end into a con-
tainer. Remove the reservoir cover; then open the
bleeder valve. Allow the brake fluid to drain until the
reservoir is empty.
2. Remove the cotter pin and pivot pin from the yoke;
then remove two cap screws and flange nuts securing
the master cylinder assembly to the frame.

Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the vehicle.
Inspecting
1. Inspect the master cylinder push rod and clevis for
wear, bending, or elongation of clevis holes.
2. Inspect the push rod boot for tears or deterioration.
3. Inspect the reservoir for cracks and leakage.
4. Inspect the brake hose for cracks and deterioration
and the condition of the banjo-fittings.
Installing
1. Place the master cylinder into position; then using
three new crush washers, secure the two banjo-fit-
tings to the master cylinder. Tighten to 20 ft-lb.
2. Secure the master cylinder assembly to the frame
with two cap screws and two flange nuts. Tighten to
25 ft-lb.
3. Install the pivot pin and secure with a new cotter pin.
4. Fill the master cylinder and bleed the brake system
