Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: BRAKE ACTUATOR: INSTALLATION (2008 Sequoia)

INSTALLATION

NOTICE:

In case of replacing the skid control ECU, perform the zero point calibration of the steering angle sensor, master cylinder pressure sensor, and yaw rate and deceleration sensor BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: CALIBRATION (2008 Sequoia) .

1. INSTALL VSC ACTUATOR WITH ACTUATOR BRACKET ASSEMBLY

(a) Install the VSC actuator with actuator bracket with the 3 nuts.

NOTICE:

Do not drop the actuator. If dropped, replace it.

(b) Tighten the 3 nuts uniformly in alphabetical order.

Torque: 22 N·m (224 kgf·cm, 16 ft·lbf)

NOTICE:

Do not damage the brake lines or wire harness.

2. CONNECT BRAKE TUBE

(a) Set each brake line to the correct position on the brake actuator as shown in the illustration.

(b) Install the clamp onto the VSC actuator bracket.

(c) Using a union nut wrench, connect the 4 brake tubes.

  • without union nut wrench

Torque: 15 N·m (155 kgf·cm, 11 ft·lbf)

  • with union nut wrench

Torque: 14 N·m (144 kgf·cm, 10 ft·lbf)

NOTICE:

  • This torque value can be obtained by using a torque wrench with a fulcrum length of 300 mm (11.8 in.) and a union nut wrench with a fulcrum length of 22 mm (0.866 in.) INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION (2008 Sequoia) .
  • This torque value is effective when union nut wrench is parallel to the torque wrench.

3. INSTALL BRAKE TUBE

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

  • without union nut wrench

Torque: 20 N·m (199 kgf·cm, 14 ft·lbf)

  • with union nut wrench

Torque: 18 N·m (185 kgf·cm, 13 ft·lbf)

NOTICE:

  • This torque value can be obtained by using a torque wrench with a fulcrum length of 300 mm (11.8 in.) and a union nut wrench with a fulcrum length of 22 mm (0.866 in.) INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION (2008 Sequoia) .
  • This torque value is effective when union nut wrench is parallel to the torque wrench.


(b) Using a union nut wrench, connect the 2 brake tubes to the VSC actuator.

  • without union nut wrench

Torque: 20 N·m (199 kgf·cm, 14 ft·lbf)

  • with union nut wrench

Torque: 18 N·m (185 kgf·cm, 13 ft·lbf)

NOTICE:

  • This torque value can be obtained by using a torque wrench with a fulcrum length of 300 mm (11.8 in.) and a union nut wrench with a fulcrum length of 22 mm (0.866 in.) INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION (2008 Sequoia) .
  • This torque value is effective when union nut wrench is parallel to the torque wrench.

4. CONNECT VSC ACTUATOR CONNECTOR

(a) Connect the VSC actuator connector.
