Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: BRAKE ACTUATOR (for Gasoline Model): INSTALLATION; 2020 - 2022 MY Corolla Corolla Hatchback GR Corolla [01/2019 - 09/2022]

INSTALLATION

CAUTION / NOTICE / HINT

w/ Electric Parking Brake System:

HINT:

The parking brake indicator light blinks (red) when the ignition switch is turned to ON after replacing the brake actuator assembly. Operate the electric parking brake switch assembly to turn off the parking brake indicator light.

PROCEDURE

1. INSTALL BRAKE ACTUATOR BRACKET CUSHION

(a) Install the 3 brake actuator bracket cushions to the brake actuator bracket assembly.

(b) Install the 3 No. 1 brake actuator case collars to the brake actuator bracket cushion.

NOTICE:

Make sure that the No. 1 brake actuator case collar is in full contact with the brake actuator bracket cushion.

(c) Install the brake actuator bracket assembly with the 3 nuts.

Torque:

19 N·m {194 kgf·cm, 14 ft·lbf}

2. INSTALL BRAKE ACTUATOR ASSEMBLY

(a) Temporarily install the brake actuator assembly with the 3 bolts.

(b) Fully tighten the 3 bolts in the order shown in the illustration.

Torque:

6.5 N·m {66 kgf·cm, 58 in·lbf}

NOTICE:

  • Do not remove the hole plugs of a new brake actuator assembly before connecting the brake tubes because the brake actuator assembly is filled with brake fluid.
  • Do not hold the brake actuator assembly by the connector.
  • Do not drop the brake actuator assembly when carrying it.

3. INSTALL BRAKE ACTUATOR WITH BRACKET

(a) Temporarily install the brake actuator with bracket to the vehicle body with the bolt and 2 nuts.

NOTICE:

  • Do not kink or damage the brake lines.
  • Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.
  • Be careful not to allow any brake fluid to enter the connector.
  • Do not hold the brake actuator assembly by the connector.
  • Do not drop the brake actuator with bracket when carrying it.

HINT:

Install the brake actuator with bracket while avoiding the brake lines.

(b) Fully tighten the bolt and 2 nuts in the order shown in the illustration.

Torque:

19 N·m {194 kgf·cm, 14 ft·lbf}

(c) Engage the 5 clamps to install a new No. 1 brake tube clamp to the brake lines.

NOTICE:

Do not kink or damage the brake lines.

(d) Temporarily tighten each brake line to the correct position on the brake actuator assembly as shown in the illustration.

NOTICE:

  • Do not kink or damage the brake line.
  • Do not allow any foreign matter such as dirt or dust to enter the brake line from the connecting parts.

(e) Using a union nut wrench, connect the 6 brake lines to the brake actuator assembly.

Torque:

Specified tightening torque (A) :

15.2 N·m {155 kgf·cm, 11 ft·lbf}

Specified tightening torque (B) :

19.5 N·m {199 kgf·cm, 14 ft·lbf}

NOTICE:

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

HINT:

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