Air Bleeding of Brake System
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 consists of two separate lines, one for front wheel brakes and the other for rear wheel brakes. Air bleeding is necessary at right and left front wheel brakes, left rear wheel brake and LSPV (if equipped), i.e.3 (4 for vehicle with LSPV) place in all.
Be sure to bleed air of brake system according to following procedure when its oil hydraulic circuit has been disconnected.

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 (1). Attach a vinyl tube (2) to bleeder plug, and insert the other end into container (3).
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 bleeder plug (M13 engine model) ( b ): 11 N·m ( 1.1 kg-m, 8.0 lb-ft)
Front caliper bleeder plug (K9K engine model) ( b ): 8.5 N·m ( 0.85 kg-m, 6.5 lb-ft)
Rear wheel cylinder and LSPV bleeder plug ( c ): 8 N·m ( 0.8 kg-m, 6.0 lb-ft)

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.
