BRAKES - HYDRAULIC SYSTEM

Bleeding
NOTE: The front and rear hydraulic systems are independent. If it is known that only one system has air in it, only that system has to be bled. Always bleed the brakes in a sequence that starts with the wheel cylinder farthest from the master cylinder and ends with the wheel cylinder or caliper closest to the master cylinder.

1. Fill the master cylinder with brake fluid.
2. Install a 3/8 in. box-end wrench to the bleeder screw on the right rear wheel.
3. Push a piece of small-diameter rubber tubing over the bleeder screw Until it is flush against the wrench. Submerge the other end Bleeding brake system of the rubber tubing in a glass jar partially fill with clean brake fluid. Make sure the rubber tube fits on the bleeder screw snugly.
4. Have a friend apply pressure to the brake pedal. Open the bleeder screw and observe the bottle of brake fluid. If bubbles appear in the glass jar, there is air in the system. When your friend has pushed the pedal to the floor, immediately close the bleeder screw before he releases the pedal.
5. Repeat this procedure until no bubbles appear in the jar. Refill the master cylinder.
6. Repeat this procedure on the left rear, right front and left front wheels, in that order. Periodically refill the master cylinder so that it does not run dry.
7. Center the pressure differential warning valve as outlined in the "Pressure Differential Warning Valve" section.
