Brake Bleeding: Service and Repair

Air Bleeding of Brake System

WARNING:
Never use brake fluid other than specified.
Otherwise, brake hose and rubber parts may get damaged or brake system may not operate normally.

CAUTION:
Brake fluid extremely damages paint.
Do not allow brake fluid to get on painted surface. Painted surfaces will be damaged by brake fluid. If any fluid spilled, flush it with water immediately.

Air bleeding operation is necessary whenever air enters into brake hydraulic lines. Brake hydraulic lines are made of diagonally split construction. If any brake pipe or hose is disconnected, bleed the disconnected line at both ends of the line.

NOTE:
Perform bleeding operation starting from wheel cylinder farthest from brake master cylinder and then at front caliper of the same brake line.








1) Fill brake master cylinder reservoir with new brake fluid and keep fluid level at least one-half of full level during bleeding operation.
Brake fluid
Refer to reservoir cap (1) of brake master cylinder or owners manual.





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-half turn.
4) When fluid pressure from bleeder plug depleted, retighten bleeder plug.
5) Repeat this operation until air is completely removed from hydraulic line.





6) After removing air completely, tighten bleeder plug to specified torque while keeping brake pedal depressed.

7) Attach bleeder plug cap.
8) After completing bleeding operation, apply fluid pressure to brake lines and check for leakage.
9) Replenish new fluid into reservoir up to specified level.
10) Check brake pedal stroke. If the stroke is so large, repeat entire procedure of bleeding.
