INSTALLATION

PROCEDURE

1. INSTALL HYDRAULIC BRAKE BOOSTER

(a) Install a new brake booster gasket onto the hydraulic brake booster.

(b) Install the hydraulic brake booster with the 4 nuts.

Torque:

14 N·m {145 kgf·cm, 10 ft·lbf}

(c) Using a union nut wrench, connect the 4 brake lines to the correct positions of the hydraulic brake booster, as shown in the illustration.

*a	to Right Rear Wheel
*b	to Right Front Wheel
*c	to Left Front Wheel
*d	to Left Rear Wheel

Torque:

without union nut wrench :

15 N·m {155 kgf·cm, 11 ft·lbf}

with union nut wrench :

14 N·m {145 kgf·cm, 10 ft·lbf}

HINT:

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.) (See page ).
This torque value is effective when the union nut wrench is parallel to the torque wrench.

(d) Connect the 3 connectors.

2. INSTALL MASTER CYLINDER PUSH ROD CLEVIS
