Brake Bleeding: Service and Repair

BRAKE: BRAKE FLUID (for 1UR-FSE): BLEEDING

BRAKE: BRAKE FLUID

CAUTION:

Bleeding without the Techstream may result in air remaining in the brake hydraulic system. As this can cause an accident, be sure to use the Techstream
for air bleeding.

NOTICE:
-

Move the shift lever to the P position 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 the pump motor operates while air remains inside the brake reservoir tube no.1 hose, the air will enter the actuator, resulting in difficulty
in bleeding. Keep the 2 ABS motor relays removed until instructed to reinstall them to prevent air from entering the brake reservoir tube
no.1 hose.

-

The actuator pump motor and solenoid can be operated by the driver even if the engine switch is off.

-

Although a buzzer may sound due to declined accumulator pressure during bleeding, keep on bleeding.

-

DTCs indicating a malfunction in the ABS motor relay or pressure sensor are stored after bleeding. Clear the DTCs when instructed during
or after bleeding.

Work list

-

*1 : The listed order must be followed.

-

*2 : If air enters the brake reservoir tube No.1 hose due to declined brake fluid level, be sure to bleed the brake reservoir tube No.1 hose.

HINT:

Refer to the Techstream operator's manual for further details.
