REMOVAL & INSTALLATION
- Detach the electrical connector from fluid level switch.
- Remove and plug the 4 brake pipe tube nuts from master cylinder. If necessary, tag for identification and placement. Place shop cloths below the master cylinder to catch any dripping fluid.
- Remove the master cylinder mounting nuts.
- Remove the master cylinder from the vacuum booster.
- Install the master cylinder to the power booster assembly and tighten the mounting nuts to 20 ft. lbs. (27 Nm).
- Connect the brake lines to the master cylinder and tighten them to 17 ft. lbs. (23 Nm).
- Attach the electrical connector to the fluid level switch.
- Fill the master cylinder to the proper level. The proper level is indicated by the MAX level marking on the fluid reservoir.
- Bleed the hydraulic brake system, as outlined later in this section.
- Road test the vehicle and verify proper brake system operation.
- Remove the master cylinder from the vehicle and secure in a soft-jawed bench vise.
- Remove the master cylinder reservoir cap.
- Manufacture or purchase bleeding tubes and install them on the master cylinder.
- Fill the master cylinder reservoir with clean, fresh brake fluid until the level is within 0.25 in. (6.35 Nm) of the reservoir top.
- Use a blunt tipped rod (a long socket extension works well) to slowly depress the master cylinder piston. Make sure the piston travels full its full stroke.
- As the piston is depressed, bubbles will come out of the bleeding tubes. Continue depressing and releasing the piston until all bubbles cease.
- Refill the master cylinder with fluid.
- Remove the bleeding tubes.
- Install the master cylinder reservoir cap.
