Base Brake System Bleeding

Air Trapped In Brake System:

NOTE: When bleeding the brake system some air may be trapped in the brake line or valving far upstream, sometimes as much as ten feet from the bleeder screw. Therefore it is absolutely essential to have a fast flow of a large volume of brake fluid when bleeding the brakes to ensure the system is purged of all air bubbles.

Bleeding Brake System:

Caliper Bleeding Screw:

NOTE: The following procedure requires 2 people.

1. Attach a clear plastic hose to the bleeder screw of the right rear wheel and insert the other end of the tube into a clear jar containing fresh brake fluid.

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 DOT 4 brake fluid.

2. Pump brake pedal 3 or 4 times and hold it down.
3. Open the bleeder screw.
4. While the bleeder screw is open push the brake pedal to the floor and hold it there.

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

5. Close the bleed screw.
6. Release the brake pedal.
7. Repeat this procedure 4 to 5 times at each bleeder screw in this order; right rear wheel, left rear wheel, right front wheel, left front wheel.
8. Check brake pedal travel. If pedal travel is excessive repeat the procedure.

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