SERVICE PROCEDURES (Continued)
Fig. 28 Pressure Bleeding Cap Installed On Master
NOTE: The following wheel sequence should be
used when bleeding the brake hydraulic system.
The use of this wheel sequence will ensure ade-
quate removal of all trapped air from the brake
hydraulic system.
• Left Rear Wheel
• Right Front Wheel
• Right Rear Wheel
• Left Front Wheel
(4) Open the left rear wheel bleeder screw at least
one full turn or more to obtain an adequate flow of
brake fluid (Fig. 29).
Fig. 29 Rear Wheel Cylinder Bleeder Screw
CAUTION: Just cracking the bleeder screw often
restricts fluid flow, and a slow, weak fluid discharge
will NOT get all the air out.
(5) After 4 to 8 ounces of brake fluid has been bled
through the hydraulic system, and an air-free flow is
maintained in the hose and jar, this will indicate a
Cylinder
good bleed of the hydraulic system has been
obtained.
(6) Repeat the procedure at all the other remain-
ing bleeder screws. Then check the pedal for travel.
If pedal travel is excessive or has not been improved,
enough fluid has not passed through the system to
expel all the trapped air. Be sure to monitor the fluid
level in the pressure bleeder, so it stays at a proper
level so air will not enter the brake system through
the master cylinder.
(7) Perform a final adjustment of the rear brake
shoes and then test drive vehicle to be sure brakes
are operating correctly and that pedal is solid.
BLEEDING WITHOUT A PRESSURE BLEEDER
NOTE: Correct manual bleeding of the brakes
hydraulic system will require the aid of a helper.
NOTE: To adequately bleed the brakes using the
manual bleeding procedure the rear brakes must be
correctly adjusted. Prior to the manual bleeding of
the brake hydraulic system, correctly adjust the
rear brakes.
NOTE: The following wheel sequence should be
used when bleeding the brake hydraulic system.
The use of this wheel sequence will ensure ade-
quate removal of all trapped air from the brake
hydraulic system.
• Left Rear Wheel
• Right Front Wheel
• Right Rear Wheel
• Left Front Wheel
(1) Pump the brake pedal three or four times and
hold it down before the bleeder screw is opened.
(2) Push the brake pedal toward the floor and hold
it down. Then open the left rear bleeder screw at
least 1 full turn. When the bleeder screw opens the
brake pedal will drop all the way to the floor.
(3) Release the brake pedal only after the bleeder
screw is closed.
(4) Repeat steps 1 through 3, four or five times, at
each bleeder screw in the required sequence. This
should pass a sufficient amount of fluid to expel all
the trapped air from the brake system. Be sure to
monitor the fluid level in the master cylinder, so it
stays at a proper level so air will not enter the brake
system through the master cylinder.
(5) Perform a final adjustment of the rear brake
shoes and then test drive vehicle to be sure brakes
are operating correctly and that pedal is solid.
