Brake Bleeding: Service and Repair
Master Cylinder Bleeding
NOTES:
^
When any part of the hydraulic system has been disconnected for service, air may enter the system causing a spongy pedal action. Bleed the
component replaced system after it has been opened to make sure that all air is expelled.
^
When a new brake master cylinder has been installed or the brake system emptied or partially emptied, fluid may not flow from the wheel cylinder
bleeder screw during normal bleeding. It may be necessary to prime the system using the following procedure.
^
Refer To Hydraulic System - Specifications for proper brake fluid requirements.
CAUTION: Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it
with water.
1. Use a tubing wrench to remove the brake tubes from the brake master cylinder.
2. Install short brake tubes in the brake master cylinder and position them so that they point back into the brake master cylinder reservoir and the
ends of the pipes are submerged in brake fluid.
3. Fill the brake master cylinder reservoir with new high performance DOT-3 motor vehicle brake fluid.
4. Cover the brake master cylinder reservoir with a clean shop towel.
5. Pump the brakes until clear, bubble-free fluid comes out of both brake tubes.
6. Remove the short brake tubes and reinstall the ones from the vehicle.
7. Bleed each brake tube at the brake master cylinder using the following procedure:
^
Have an assistant pump the brake pedal 10 times and then hold firm pressure on the brake pedal.
^
Loosen the front brake tube fittings with a tubing wrench until a stream of brake fluid comes out. Assistant should maintain pressure on the
brake pedal until the brake tube fitting is tightened again.
^
Repeat this operation until clear, bubble-free fluid comes out from around the tubing fitting.
^
Repeat this bleeding operation at the rear brake tube fitting.
8. If any of the brake tubes or rear disc brake calipers have been removed, it may be helpful to prime the system by gravity bleeding it. This should
be done after the brake master cylinder has been primed and bled. To prime the brake system:
^
Fill the brake master cylinder with new DOT-3 motor vehicle brake fluid.
^
Loosen both rear bleeder screws and leave open until clear brake fluid flows out. Do not let the brake master cylinder reservoir run dry, check
reservoir often.
^
Tighten the wheel cylinder rear wheel cylinder bleeder screws.
^
One at a time, loosen the rear wheel cylinder bleeder screws. Leave the bleeder screws open until clear fluid flows out. Do not let the brake
master cylinder reservoir run dry check reservoir often.
^
Tighten the wheel cylinder bleeder screws to 7-9 Nm (62-79 inch lbs.).
9. After the brake master cylinder has been primed, the tubes bled at the brake master cylinder, and the brake system primed, normal brake system
bleeding can resume at each wheel.
