Manual Bleeding

Bleeding the brake system by pumping the brake pedal is the most economical method. The only disadvantage is that it requires a helper.

When manually bleeding the brakes, first fill the brake fluid reservoir on top of the master cylinder until the level is well above the MAX mark, and replace the cap to prevent contamination of the fluid.

Starting with the right rear caliper or cylinder, clean the area around the bleeder valve and remove the dust cap. Fit the box wrench to the bleeder valve, then slip one end of the hose onto the valve and submerge the other end in clean brake fluid in the clear container. Have a helper slowly pump the brake pedal about three times and, on the last time, hold it down. Slowly open the bleeder valve approximately one-half turn. When the brake pedal goes to the floor and fluid stops flowing from the bleeder valve, close the bleeder valve, then release the brake pedal.

CAUTION-

Until some pressure has built up in the system, only depress the pedal approximately halfway. This will prevent overrunning the master cylinder's normal stroke, which may damage the master cylinder piston seals, especially on older, high mileage cars.

CAUTION-

Be sure that the bleeder valve is fully closed before releasing the brake pedal to avoid drawing air back into the bleeder valve.

Repeat the procedure until clear fluid with no air bubbles is coming from the bleeder valve, then fully tighten the valve and replace the dust cap. Using the sequence described above, follow the same procedure at the other three wheels. Check the fluid level in the master cylinder frequently, and add more to keep the level at the MAX mark.
