Brake Bleeding: Service and Repair

NOTE: For additional information see Fundamentals and Basics. Fundamentals and Basics

CAUTION:
- Make sure all parts are clean before reassembly.
- Use only clean brake fluid.
- Do not allow dirt or other foreign matter to contaminate the brake fluid.
- Do not mix different brands of brake fluid.
- Avoid spilling brake fluid on painted, plastic or rubber surfaces as it can damage the finish; Wash spilled brake fluid off immediately with clean water.

NOTE: The reservoir on the master cylinder must be full at the start of bleeding procedure, and checked after bleeding each wheel cylinder. Add fluid as required. Use only DOT 3 or 4 brake fluid.

BRAKE BLEEDING SEQUENCE

Brake System Bleeding Sequence:

1. Have someone slowly pump the brake pedal several times, then apply steady pressure.

Brake Bleeding:

2. Loosen the brake bleed screw to allow air to escape from the system. Then tighten the bleed screw securely.

NOTE: Do not release the brake pedal until the bleeder valve is fully shut.

3. Repeat the procedure for each wheel in the sequence shown above, until air bubbles no longer appear in the fluid.

WARNING: Do not bleed the brakes with the drums removed. The wheel cylinders will over-extend and eject the pistons.
