INSTALLATION

PROCEDURE

1. INSTALL BRAKE ACTUATOR ASSEMBLY

(a) Install the brake actuator assembly to the brake actuator bracket assembly with the 2 nuts.

Torque:

8.0 N·m {82 kgf·cm, 71 in·lbf}

NOTICE:

Do not remove the hole plugs of a new brake actuator before connecting the 6 brake lines because the brake actuator is filled with brake fluid.
Do not hold the actuator by the connector.
Set the actuator down with the pin being set securely as shown in the illustration.

2. INSTALL BRAKE ACTUATOR WITH BRACKET

(a) Install the brake actuator with bracket to the body with the nut and 2 bolts.

Torque:

19 N·m {194 kgf·cm, 14 ft·lbf}

NOTICE:

Do not damage the brake lines or wire harness.
Tighten the nut and 2 bolts in order from 1 to 3.

(b) Connect the brake actuator connector.

NOTICE:

Make sure that the connector is locked securely.
Make sure that the actuator connector can be connected smoothly. Do not allow water, oil or dirt to enter.

(c) Temporarily tighten each brake line to the correct positions of the brake actuator with bracket as shown in the illustration.

14 N*m (142 kgf*cm, 10 ft.*lbf)

(e) Using a union nut wrench, fully tighten 2 brake lines (B).

Torque:

Specified Tightening Torque :

20 N·m {199 kgf·cm, 14 ft·lbf}

HINT:

Calculate the torque wrench reading when changing the fulcrum length for the torque wrench (See page ).
When using a union nut wrench (fulcrum length of 20 mm (0.787 in.)) + torque wrench (fulcrum length of 250 mm (9.84 in.)):
18 N*m (184 kgf*cm, 13 ft.*lbf)

(f) Install the clamp of the suction hose sub-assembly to the brake actuator bracket assembly.
