System Bleeding Procedure
CAUTION: Brake fluid is extremely damaging to paint. If fluid should accidentally touch painted surface, immediately wipe fluid from saint and clean painted surface.
NOTE:
- For vehicle equipped with Antilock Brake System (ABS), bleed air.
- When master cylinder has been removed or disassembled, or brake pipe has been disconnected from master cylinder, bleed air from master cylinder to facilitate bleeding air of brake system. Then proceed to following operation.
Be sure to bleed air of brake system according to following procedure when its oil hydraulic circuit has been disconnected.
Hydraulic lines of brake system consists of two separate lines, one for front wheel brakes and the other for rearwheel brakes. Air bleeding is necessary at right and left front wheel brakes, left rear wheel brake and LSPV, i.e. 4 places in all.
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 to bleeder plug of wheel cylinder, and insert the other end into container.
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 the cylinder is almost depleted, retighten bleeder plug.
5) Repeat this operation until there are no more air bubbles in hydraulic line.
6) When bubbles stop, depress and hold brake pedal and tighten bleeder plug.
Tightening torque:
Front caliper: 9.0 Nm (6.5 ft lb)
Rear Cylinder: 8.0 Nm (6.0 ft lb)
7) Then attach bleeder plug cap.
8) After completing bleeding operation, apply fluid pressure to pipe line and check for leakage.
9) Replenish fluid into reservoir up to specified level.
10) Check brake pedal for "sponginess". If found spongy, repeat entire procedure of bleeding.
