Manual Extract: Brake Fluid Line Bleeding Test

When a part of the brake fluid line is disassembled for repair, or when brake pedal movement is spongy, bleed the brake fluid line.
Bleeding work requires two people. Turn ON the engine and keep it idling during bleeding operation.

(1) Fill the reserve tank with brake fluid. Always keep the brake fluid level more than half full of the reserve tank during bleeding operation.
(2) Insert a vinyl tube on the bleeder screw of the wheel cylinder. Insert the other end of the tube to a container filled with brake fluid.
(3) Have one person depress (pump) on the brake pedal several times and while holding the pedal depressed, release the bleeder screw. Before the brake fluid stops flowing in the vinyl tube, tighten the bleeder screw.
(4) Repeat the above Steps until there is no air bubbles in the brake fluid. Fill the reserve tank with brake fluid to the specified level.

Note:
– If brake pedal feels soft, a vacuum pump may be needed to bleed all the air out of the master cylinder, lines, and wheel cylinders.
– BE SURE to maintain sufficient fluid level in the reserve tank.
– Use brake fluid of the specified brand. Do not mix different types of brake fluids.
– Start bleeding work of the brake fluid of the wheel cylinder from the right side (far side from the master cylinder).
