Brake Bleeding: Service and Repair

BRAKE SYSTEM (OTHER): BRAKE FLUID: BLEEDING

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

NOTICE:
* Move the shift lever to P and apply the parking brake before bleeding the brakes.
* Add brake fluid to keep the level between MIN and MAX lines of the reservoir while bleeding the brakes.
* If brake fluid leaks onto any painted surface, wash off and remove the brake fluid completely.

2. BLEED BRAKE MASTER CYLINDER

NOTICE:
* If the master cylinder is reinstalled or runs out of brake fluid, bleed the master cylinder.
* To prevent brake fluid from damaging painted surfaces, cover any surrounding parts with a piece of cloth.

(a) Using a union nut wrench (10 mm), disconnect the 2 brake lines from the brake master cylinder sub-assembly.





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





(c) Cover the 2 outer holes with fingers, and release the brake pedal.*2





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

(e) Using a union nut wrench (10 mm), connect the 2 brake lines to the master cylinder.

without a union nut wrench - Torque : 15 Nm (153 kgf-cm, 11 ft-lbf)

with a union nut wrench - Torque : 14 Nm (143 kgf-cm, 10 ft-lbf)

NOTICE:
* Use a torque wrench with a fulcrum length of 250 mm (9.84 in.).
* This torque value is effective when the union nut wrench is parallel to the torque wrench.

4. BLEED BRAKE ACTUATOR

NOTICE:
After bleeding the air from the brake system, if the correct height or feel of the brake pedal cannot be obtained, bleed the air from the brake actuator assembly with the Techstream by following the procedures below.

(a) Depress the brake pedal more than 20 times with the engine switch off.

(b) Connect the Techstream to the DLC3, then turn the engine switch on (IG).

NOTICE:
Do not start the engine.

(f) Turn the Techstream off and disconnect the Techstream from the DLC3.

(g) Turn the engine switch off.
