Before attempting any service on the front brake system of your vehicle, determine what type of hardware secures the calipers, so you can purchase the correct tools.
- Raise the front of the vehicle and safely support on jackstands.
- Remove the front wheel and tire assemblies.
- The cut out in the top of the front brake caliper allows visual inspection of the disc brake pad. If the lining is worn to within 1 / 8 in. (3mm) of the metal disc shoe (check local inspection requirements) replace all four pads (both sides).
- While you are inspecting the brake pads, visually inspect the caliper for hydraulic fluid leaks. If a leak is visible the caliper will have to be rebuilt or replaced.
It is recommended that brake pads be replaced in sets of 4, 2 for each side.
REMOVAL & INSTALLATION
See Figures 1 through 5
When you replace the front brake pads, if the brake fluid has not been replaced within the last two years, this is a good time to change the fluid. By removing the fluid from the reservoir prior to unfastening the pads, you will reduce the chance of brake fluid overflowing into the engine compartment when the pistons are fully compressed. And since brake fluid can easily absorb water which can effect braking performance and the longevity of the master cylinder and other brake components, routine service is a worthwhile investment of time.
- If changing the brake fluid, remove the master cylinder cap and remove as much brake fluid as possible. Discard brake fluid properly.
- Raise and safely support the vehicle on jackstands.
- Remove the wheel and tire assembly.
- Remove the caliper locating pins using either a hex or a Torx&® socket.
- Lift the caliper assembly from the integral knuckle and anchor plate and rotor using rotating motion. Do not pry directly against plastic piston or damage will occur.
- Remove the outer and inner brake pads.
- Inspect both rotor braking surfaces. Minor scoring or buildup of lining material does not require machining or replacement of rotor. Hand-sand glaze from both rotor braking surfaces using garnet paper 100-A (medium grit) or aluminum oxide 150-J (medium).
- Suspend the caliper inside fender housing with wire. Use care not to damage caliper or stretch brake hose.
- Use a 4 in. C-clamp and wood block 2 3 / 4 in. x 1 in. (70mm x 25mm) and approximately 3 / 4 in. (19mm) thick against the piston, and turn the C-clamp to seat caliper hydraulic piston in its bore.
Extra care must be taken during this procedure to prevent damage to the plastic piston. Metal or sharp objects cannot come into direct contact with the piston surface or damage will result.
- Remove all rust buildup from inside of caliper legs where the outer shoe makes contact.
- Install the inner pad by sliding the clips into place, with the center of the pad on top of the piston. Do not bend the pad clips during installation.
- Install the outer pad to the caliper, securing it with the clips. Ensure clips are properly seated.
- Install the caliper over rotor.
- Position and secure caliper locating pins.
- If changing the brake fluid, fill the brake fluid reservoir with clean brake fluid. Bleed the brakes.
- Check the brake fluid level in the reservoir, and adjust if needed. Install the wheel and tire assembly. Tighten wheel nuts to 80-105 ft. lbs. (109-142 Nm).
- Connect negative battery cable.
- Road test vehicle.
