Brake Bleeding: Service and Repair
Air Bleeding
CAUTION: Brake fluid is extremely damaging to paint. If fluid should accidentally touch painted surface, immediately wipe fluid from paint and
clean painted surface.
Bleeding operation is necessary to remove air whenever it entered hydraulic brake system. Hydraulic lines of brake system are based on the diagonal
split system. When a brake pipe or hose was disconnected at the wheel, bleeding operation must be performed at both ends of the line of the removed
pipe or hose. When any joint part of the master cylinder of other joint part between the master cylinder and each brake (wheel) was removed, the
hydraulic brake system must be bled at all 4 wheel brakes.
NOTE: Perform bleeding operation starting with wheel cylinder farthest from master cylinder and then at front caliper of the same brake line. Do the
same on the other brake line.
1. Fill master cylinder reservoir with brake fluid and keep at least one-half full of fluid during bleeding operation.
2. Remove bleeder plug cap. Attach a vinyl tube (1) to bleeder plug, and insert the other end into container (2).
3. Depress brake pedal several times, and then while holding it depressed, loosen bleeder plug about one-third to one-half turn.
4. When fluid pressure in cylinder is almost depleted, retighten bleeder plug.
