When replacing the disc with a new one, select the installation position where the disc has the minimum runout.

2. INSPECT DISC RUNOUT

(a) Temporarily install the front disc with the hub nuts.

Torque:

113 N·m {1152 kgf·cm, 83 ft·lbf}

(b) Using a dial indicator, measure the disc runout 10 mm (0.394 in.) away from the outer edge of the front disc.

Maximum disc runout:

0.05 mm (0.00197 in.)

If the disc runout is the maximum value or greater, check the bearing play in the axial direction and check the axle hub runout (See page are normal, adjust the disc runout or grind it on an on-car brake lathe. ). If the bearing play and axle hub runout are normal, adjust the disc runout or grind it on an on-car brake lathe.

3. INSTALL DISC BRAKE CYLINDER ASSEMBLY

(a) Install the disc brake cylinder assembly with the 2 bolts.

Torque:

123 N·m {1254 kgf·cm, 91 ft·lbf}

(b) Using a union nut wrench 10 mm, install the brake tube to the disc brake cylinder assembly.

Torque:

15 N·m {155 kgf·cm, 11 ft·lbf}

NOTICE:

Use the formula to calculate special torque values for situations where a union nut wrench is combined with a torque wrench (See page 4. INSTALL FRONT ANTI SQUEAL SHIM KIT ).

4. INSTALL FRONT ANTI SQUEAL SHIM KIT

(a) Install the 2 front anti squeal shims onto each of the front disc brake pads.

NOTICE:

If necessary, replace the anti-squeal shim kit when replacing the brake pad.

5. INSTALL FRONT DISC BRAKE PAD KIT

(a) Install the 2 front disc brake pads with front anti-squeal shim onto the disc brake cylinder assembly.

6. INSTALL FRONT DISC BRAKE ANTI-RATTLE WITH HOLE PIN

(a) for Pin Hold Clip Type A:

(1) Install the anti-rattle spring to the front disc brake pad.

NOTICE:

The anti-rattle spring can be used again if it has sufficient rebound; no deformation, cracks or wear; and has had all rust, dirt and foreign matter cleaned off.

(2) Install the 2 front disc brake anti-rattle with hole pins to the disc brake cylinder assembly.

(3) Install the pin hold clip to the 2 front disc brake anti-rattle with hole pins.

NOTICE:
