BLEEDING

CAUTION / NOTICE / HINT

NOTICE:

Move the shift lever to P and apply the parking brake before bleeding the brakes.
Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brakes.
If brake fluid leaks onto any painted surface, immediately wash it off.
Do not operate the brake actuator assembly while air is in the brake system or in the brake master cylinder sub-assembly. Doing so may cause air to enter the brake actuator assembly.
If bleeding the brake actuator assembly is difficult due to air in the brake actuator assembly, replace it with a new one.

When bleeding air, select the suitable procedure listed below.

Replaced/Installed Item	Work Procedure
Flexible hose (front/rear)	Bleed brake line
Disc brake cylinder assembly (front)
Brake actuator assembly
Brake master cylinder sub-assembly
Brake master cylinder reservoir sub-assembly
Brake booster assembly
Disc brake cylinder assembly (rear)	Bleed rear disc brake cylinder assembly

HINT:

If any work is performed on the brake system or if air in the brake tubes is suspected, bleed the air from the brake system.

PROCEDURE

1. FILL RESERVOIR WITH BRAKE FLUID

2. BLEED BRAKE MASTER CYLINDER SUB-ASSEMBLY

NOTICE:

To prevent brake fluid from damaging painted surfaces, cover any surrounding parts with a piece of cloth.
Be sure to clean your hands before bleeding the master cylinder to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.

HINT:

If the brake master cylinder sub-assembly is reinstalled or runs out of brake fluid, bleed the brake master cylinder sub-assembly.

(a) Using a union nut wrench, disconnect the 2 brake tubes from the brake master cylinder sub-assembly.

NOTICE:

Do not damage or deform the brake lines during the removal procedure.
Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.

(b) Slowly depress the brake pedal and hold it.*1

(d) Repeat steps *1 and *2, 3 or 4 times.

(e) Using a union nut wrench, connect the 2 brake tubes to the brake master cylinder sub-assembly.

Torque:

Specified tightening torque :

19.5 N·m {199 kgf·cm, 14 ft·lbf}

NOTICE:

Do not kink or damage the brake tubes.
Do not allow the brake tubes to twist and interfere with other parts or vehicle body during tightening.
Do not allow any foreign matter such as dirt or dust to enter the brake tubes.

HINT:

Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
