Brake Bleeding: Service and Repair
Bleeding operation calls for co-operative action of two persons. Perform bleeding operation with ``Engine Running,'' to prevent damage to pushrod
seal. Ensure exhaust system is suitably ventilated.
1.
Set the parking brake firmly.
2.
If diaphragm in the reservoir cap is stretched, reform to original position or replace as necessary. Fill the brake fluid reservoir with recommended
brake fluid, then install cap.
3.
Connect a vinyl hose to the bleeder screw and the other end of the pipe in a transparent container.
4.
Pump the brake pedal several times and hold it depressed. Loosen the bleeder screw to release brake fluid together with air bubbles. Tighten the
bleeder screw before pressure is released completely.
5.
Repeat Step 4 until the air bubbles are no longer visible, bleed the system starting with the rear side farthest from the brake fluid reservoir. Check
brake fluid reservoir often, adding fluid as necessary.
