The hydraulic brake system must be free of air to operate correctly. Air can enter the system when hydraulic parts are
disconnected for servicing or replacement, or when the fluid level in the master cylinder reservoir is very low. Air in the
system will give the brake pedal a soft feel on application.
An assistant will be necessary for this procedure.
1. Use a clean cloth to wipe off the master cylinder reservoir and wheel cylinder bleeder valves. Clean each fitting
before opening to prevent contaminating the system.
2. Open the master cylinder reservoir and fill to the top with standard auto-
motive DOT 3 brake fluid.
Never return brake fluid to the original container or reuse brake
fluid because of possible contamination by dirt, grease or
moisture. Contaminated brake fluid can cause failure of the
braking system. Discard brake fluid according to Federal, state
and local codes.
3. Attach a short length of clear hose to the caliper bleed valve and install
the other end into a clean container containing new, clean brake fluid.
Check the fluid level in the master cylinder frequently during this operation to prevent air from entering the
brake system.
4. Bleed the brakes in the following order: Passenger side rear brake first, then the driver side rear brake. Next bleed
the passenger side front brake and driver side front brake last. Bleeding the brakes requires an assistant to pump
the brake pedal and keep pressure on the pedal. Bleed the brakes using the following procedure:
a. Build pressure in the brake system, if possible, by slowly pumping the brake pedal.
b. Open the bleeder valve while an assistant holds pressure on the brake pedal as the pedal slowly goes through
the full stroke.
c. Close the bleeder valve and have the assistant slowly release the brake pedal.
d. Repeat the send until no bubbles can be seen leaving the bleeder valve.
e. Close the valve and move to the next brake.
