Brake Pads Replacement - Front
FRONT DISC BRAKES/FRONT PADSREMOVAL
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 front wheel and tire assemblies.
3. Pry off locking plate and remove brake pressure hose from strut.
4. Remove caliper retainer spring.
NOTICE: Do not let weight of caliper hang on brake hose as this could damage the brake hose. Use mechanics wire to tie caliper to strut.
5. Remove caliper-to-bracket guide pins.
6. Remove caliper assembly.
7. Remove inboard and outboard brake pads from caliper assembly.
8. Inspect:
^ Guide pin boots and covers for damage. If damaged, replace.
^ Piston boot for deterioration. If damage, overhaul the caliper.
^ Guide pin for damage or corrosion. Replace if damaged or corroded (do not attempt to clean away corrosion).
9. Repeat steps 3 through 8 for opposite side of vehicle.
INSTALLATION
IMPORTANT: Never replace brake pads on one side of axle only. Left and right side brake pads must be replaced only as axle sets. Piston boot must lie flat, below level of the piston face.
1. Using a C-clamp, bottom piston all way into caliper bore.
NOTICE: Linings are identified for left or right use. Install linings so arrow is pointing downward, with forward rotation of wheel.
IMPORTANT: Remove all rust and corrosion from caliper brackets when installing brake pads. If installing used brake pads, remove all rust and corrosion from ends of brake pads and from the notch. Make sure brake pads move freely in caliper bracket when brakes are assembled.
2. Install inner and outer brake pads into calipers.
3. Position caliper onto caliper support bracket.
NOTICE: Be careful not to damage guide pin boots.
4. Lubricate straight section (not threads) of guide pins with silicone grease.
5. Install guide pins through caliper body into caliper support and tighten.
Torque: Caliper-to-Bracket Guide Pins: 30 Nm (22 ft. lbs.)
6. Install guide pin bushing caps.
7. Install caliper retention spring.
8. Re-attach brake hose to strut assembly and install lock plate
9. Repeat steps 1 through 7 for opposite side of vehicle.
NOTICE: Before installing wheels, remove rust or corrosion from wheel mounting surfaces and brake rotors. Failure to do so can cause wheel bolts to loosen in service.
10. Position wheel onto hub.
11. Install wheel bolts and tighten in a star pattern.
11.1 Hand tighten all five wheel bolts.
11.2 Use a torque wrench to tighten wheel bolts using a star pattern.
Torque: Wheel Bolts (Initial Torque): 63 Nm (46 ft. lbs.)
11.3 Use a torque wrench to final tighten wheel bolts using a star pattern.
Torque: Wheel Bolts (Final Torque): 125 Nm (92 ft. lbs.)
12. Lower vehicle from hoist.
CAUTION: IF THIS OPERATION IS NOT CARRIED OUT, BRAKES WILL NOT OPERATE PROPERLY DURING INITIAL BRAKE APPLICATIONS.
13. Prior to operating vehicle, depress the brake pedal a few times until brake pads are seated against rotor.
