FRONT ROTOR

REMOVAL

CAUTION: MAKE SURE VEHICLE IS PROPERLY SUPPORTED AND SQUARELY POSITIONED ON THE HOIST. TO HELP AVOID PERSONAL INJURY WHEN A VEHICLE IS ON A HOIST, PROVIDE ADDITIONAL SUPPORT FOR THE VEHICLE ON THE OPPOSITE END FROM WHICH COMPONENTS ARE BEING REMOVED.

1. Raise vehicle on hoist.
2. Remove wheel and tire assembly.
3. Remove caliper support to steering knuckle bolts. Remove caliper assembly and suspend it from the strut spring with mechanics wire.





4. Remove rotor.

INSTALLATION

NOTICE: Before installing rotors, remove any rust or corrosion from hub mounting surfaces and brake rotors. Failure to do so can cause wheel nuts to loosen in service.

1. Install rotor onto wheel hub.

NOTICE: Clean caliper support bracket fasteners thoroughly with brake and choke cleaner (PIN 21007432 or equivalent). Apply Permatex (R) Permanent Strength Threadlocker Red, 26240 (P/N 21005994) (or equivalent) to caliper support bracket fasteners. If Permatex (R) Permanent Strength Threadlocker Red, 26240 (PIN 21005994) (or equivalent) is not available, new caliper support bracket fasteners must be used.

IMPORTANT: If a new rotor is installed it may be necessary to seat the caliper pistons.





2. Install caliper support onto steering knuckle.

NOTICE: If a new caliper bracket is installed, torque caliper bracket-to-knuckle bolts to 185 Nm (136 lb ft).

Torque:
Brake Caliper Bracket-to-Steering Knuckle: 160 Nm (118 lb ft)

NOTICE: Before installing wheels, remove rust or corrosion from wheel mounting surfaces and brake rotors/drums. Failure to do so can cause wheel nuts to loosen in service.

3. Position wheel onto hub.
4. Install wheel nuts and tighten in a crisscross pattern. Repeat tightening pattern to be sure torque is correct.
Torque:
Wheel Nut: 125 Nm (92 lb ft)

5. Lower vehicle from hoist.

CAUTION: IF THIS OPERATION IS NOT CARRIED OUT, BRAKES WILL NOT OPERATE PROPERLY DURING INITIAL BRAKE APPLICATIONS.

6. Prior to operating vehicle, depress the brake pedal several times until brake pads are fully seated against rotor.
