Front

CAUTION: Inner and outer pads must be new or parallel. Parking brake adjustment is not valid with tapered pads, and may cause caliper/parking brake binding. This will result, in overheating and possible damage of the brake linings, rotor, and/or caliper.

Front Caliper:

REMOVE OR DISCONNECT
1. Two-thirds of the brake fluid from master
2. Raise vehicle and suitably support
3. Mark relationship of wheel to hub.
4. Tire and wheel. Install two wheel nuts to retain rotor.
5. Push pistons onto caliper bores to provide clearance between linings and rotor.
a. Install a large C-clamp over top of caliper housing and against back of outboard pad.
b. Slowly tighten C-clamp until pistons and pushed into the caliper bores enough to slide the caliper off rotor.

Removing Outboard Brake Pad:

6. Outboard brake pad. Use a screwdriver to lift up the outboard pad retaining spring so that it will clear caliper center lug.
7. Inboard brake pad, unsnapping pad springs from inside of piston.

NOTE: Inspect pin boots for cuts, tears or deterioration. Replace if damaged. Inspect piston boots for cuts, tears, or deterioration. If damaged, replace boots. Inspect rubber bushing in caliper mounting bracket for cuts, tears, or deterioration. If damaged, replace bushing. Inspect slide pin bolts for corrosion or damage. If corrosion is found, use new parts including bushings when installing caliper. Do not attempt to polish away corrosion. Before installing new brake pads, wipe outside surface of caliper boot clean. Use denatured alcohol.

INSTALL OR CONNECT
1. Bottom pistons into caliper bores using a C-clamp if new brake pads are to be installed. Using C-clamp, clamp, both pistons at the same time with a metal plate or wooden block across the face of both pistons.

CAUTION: Take care not to damage pistons or caliper boot.

Lifting Piston Boot:

NOTE: After bottoming pistons, lift inner edge of the caliper boots next to the pistons and press out any trapped air. Boots must lay flat below the level of the piston face.

2. Inboard brake pad by snapping pad retainer springs into inside of piston. Pad retainer springs are already staked to the inboard pad.

NOTE: Make sure both tangs of the retainer springs are installed inside the piston ID. Pad must lay flat against pistons. After, installing brake pads, check that caliper boots are not touching the pads. If there is contact, remove brake pads and re-seat or re-position boots.

Installing Outboard Brake Pad:

3. Outboard brake pads by snapping outboard pad retaining springs over caliper center lug and into housing slot. Wear sensor should be at the trailing edge of the pad during forward wheel rotation. Back of pad must lay flat against caliper.
4. Caliper over rotor and caliper mounting bracket. Make sure bushings are in place.
5. Lubricate caliper slide pin bolts using silicone grease. Do not lubricate threads.
6. Lubricate two rubber bushings in caliper mounting bracket using silicon grease.
7. Caliper slide pin bolts. Using a screwdriver push pin boot over shoulder of pin bolt. Pin boot must be securely in grove of pin bolt. Tighten slide Pin Bolts to 108 Nm (80 ft.lbs.).
8. Remove wheel nuts securing rotor to hub.
9. Tires and wheels. Align previous marks on wheel and hub.
10. Lower vehicle.
11. Fill master cylinder to proper level with clean brake fluid.
12. Apply approximately 778 N (175 lb.) force three times to brake, pedal to seat linings.
13. Burnish pads and rotors.

NOTE: After brake pads have been replaced and/or rotors have been refinished, it is recommended that the new braking surface be broken in, or "burnished." This can be accomplished by making 20 stops from 48 km/h (30 mph) using medium to firm pressure. Take care to avoid overheating the brakes.
