Removal & Installation
- Raise and support the vehicle safely.
- Remove the front wheels.
- Remove a small amount of brake fluid from the reservoir using a suction pump.
- Unbolt the brake hose clamp from the knuckle by removing the retaining bolts.
- Remove the lower caliper retaining bolt and pivot the caliper upward, off of the pads.
- Remove the pad shim and pad retainers. Remove the disc brake pads from the caliper.
- Clean the caliper thoroughly; remove any rust from the lip of the disc or rotor. Check the brake rotor for grooves or cracks. If any heavy scoring is present, the rotor must be replaced.
- Install the pad retainers. Apply molybdenum brake grease to both surfaces of the shims and the back of the disc brake pads.
- Install the pads and shims. The pad with the wear indicator goes in the inboard position.
- Push in the caliper piston so the caliper will fit over the pads. This is most easily accomplished with a pad spreader or large C-clamp.
- Pivot the caliper down into position and tighten the mounting bolt.
- Connect the brake hose to the knuckle, if removed.
- Install the wheel and lower the vehicle to the ground.
- Add brake fluid to the master cylinder reservoir and install the cap.
- Depress the brake pedal several times and make sure that the movement feels normal. The first brake pedal application may result in a very long pedal action due to the pistons being retracted. Always make several brake applications before starting the vehicle. Bleed the system if necessary.
- Raise the front of the vehicle, and support it with safety stands in the proper locations.
- Remove the front wheels.
While holding the caliper pin (A) with a wrench, remove the flange bolt (B). Be careful not to damage the pin boot. Then pivot the caliper (C) up out of the way. Check the hose and pin boots for damage and deterioration.
- Remove the pad shims and brake pads.
Remove the pad retainers (A) from the caliper bracket (B).
- Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.
- Check the brake disc for damage and cracks.
- Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the retainers on their mating surfaces (indicated by the arrows) against the caliper bracket.
- Install the pad retainers. Wipe excess paste off the retainers. Keep paste off the discs and pads.
- Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the pad side of the shims, the back of the brake pads and the other areas indicated by the arrows. Wipe excess assembly paste off the shims and brake pads. Contaminated brake discs or brake pads reduce stopping ability. Keep grease and assembly paste off the brake discs and brake pads.
- Install the brake pads and pad shims correctly. Install the brake pad with the wear indicator on the inside. If you are reusing the brake pads, always reinstall the brake pads in their original positions to prevent a loss of braking efficiency.
Mount the special tool (A) on the caliper (B).
Press in the piston with the special tool so the caliper will fit over the brake pads. Make sure the piston boot is in position to prevent damaging it when pivoting the caliper down.
NOTEBe careful when pressing in the piston, brake fluid might overflow from the master cylinder's reservoir.
- Remove the special tool.
Pivot the caliper down into position. Install the flange bolt (A), and torque it to the specified torque while holding the caliper pin (B) with a wrench. Be careful not to damage the pin boot.
Press the brake pedal several times to make sure the brakes work.
NOTEEngagement of the brakes may require a greater pedal stroke immediately after the brake pads have been replaced. Several applications of the brake pedal will restore the normal pedal stroke.
- After installation, check for leaks at hose and line joints or connections, and retighten if necessary.
- Install the front wheels, then test-drive the vehicle.
