CAUTION:
• Be sure to install so that the pad return
spring faces the input side of the direction of
brake rotor rotation, as shown in the figure.
• Correctly install the pad return spring to the
supporting surface of the pad clip as shown in
the figure.
• If the pad return spring is deformed or dam-
aged, replace the brake pad.

3. Front Disc Rotor

A: REMOVAL

1. 16-INCH TYPE

1) Lift up the vehicle, and remove the front wheels.
2) Remove the caliper body and the support from
housing, and suspend it from the strut using a wire.

3) Remove the disc rotor.

NOTE:
If it is difficult to remove the disc rotor from the hub,
drive an 8 mm bolt into the threaded section (B) of
the rotor, then remove the rotor.

4) Remove mud and foreign matter from the caliper
body assembly and the support.

2. 17-INCH TYPE

Refer to 16-inch type. <Ref. to BR-14, 16-INCH
TYPE, REMOVAL, Front Disc Rotor.>

B: INSTALLATION

1) Install the disc rotor.
2) Install the caliper body and the support to hous-
ing.

Tightening torque:

120 N·m (12.2 kgf-m, 88.5 ft-lb)

3) Install the front wheels.

C: INSPECTION

1) Check the front wheel bearing play and axle hub
runout before the inspection of disc rotor runout
limit. <Ref. to DS-16, INSPECTION, Front Axle.>
2) Secure the disc rotor by tightening the five wheel
nuts.
3) Set a dial gauge 10 mm (0.39 in) inward from the
disc rotor outer circumference. Rotate the disc rotor
to check runout. If the disc rotor runout exceeds the
limit, resurface the disc rotor. After grinding, check
the thickness of the disc rotor according to the pro-
cedure in step 4).

Disc rotor runout limit:

0.05 mm (0.0020 in)

4) Set a micrometer 10 mm (0.39 in) inward from
the disc rotor outer perimeter, and then measure
the disc rotor thickness. If the thickness of disc ro-
tor exceeds the service limit, replace with a new
disc rotor.
