| 10. BLEED BRAKE SYSTEM |
- CAUTION:
- If air is bled without using the GTS, damage or accidents may result. Therefore, always use the GTS when bleeding air.
Turn the ignition switch to ON.
Remove the brake master cylinder reservoir filler cap assembly.
Add brake fluid until the fluid level is between the MIN and MAX lines of the reservoir.
Repeatedly depress the brake pedal and bleed air from the bleeder plug of the front disc brake cylinder RH.
Repeat the step above until the air is completely bled, and then tighten the bleeder plug while depressing the brake pedal.
- Torque:
- 11 N*m{ 110 kgf*cm, 8 ft.*lbf}
Bleed the air from the bleeder plug of the front disc brake cylinder LH using the same procedure as for the RH side.
With the brake pedal depressed, loosen the bleeder plug of the rear disc brake cylinder RH, continue to hold the brake pedal and allow brake fluid to be drained from the bleeder plug while the pump motor operates.
- HINT:
When there is no more air in the brake fluid, tighten the bleeder plug, and then release the brake pedal.
- Torque:
- 11 N*m{ 110 kgf*cm, 8 ft.*lbf}
Bleed the air from the bleeder plug of the rear disc brake cylinder LH using the same procedure as for the RH side.
Turn the ignition switch off and connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Chassis / ABS/VSC/TRC / Utility / Air Bleeding.
- NOTICE:
- To protect the solenoid from overheating, the solenoid operation stops automatically in 4 seconds, and then the solenoid will not respond to commands for an additional 20 seconds.
Repeatedly depress the brake pedal several times, and then, with the brake pedal depressed, turn FR on and bleed air.
- HINT:
- Air returns to the brake master cylinder reservoir together with the brake fluid and is bled from the brake system.
- NOTICE:
Turn FL on and bleed air using the same procedures as for FR.
Turn RR on, loosen the bleeder plug of the rear disc brake cylinder RH and drain brake fluid.
- HINT:
