Front Disc Brake Pads Replacement
Front Disc Brake Pads Replacement (2.4L Engine)
Removal Procedure
Warning: Refer to Brake Dust Warning (Brake Dust Warning).
Warning: Refer to Brake Fluid Irritant Warning (Brake Fluid Irritant Warning).
Caution: Refer to Brake Fluid Effects on Paint and Electrical Components Caution (Vehicle Damage Warnings).
1. Use a siphon in order to remove half of the brake fluid from the master cylinder reservoir.
2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle (Service and Repair).
3. Remove the front tire and wheel assembly from the vehicle. Refer to Tire and Wheel Removal and Installation (Service and Repair).
4. Install a large C-clamp over the brake caliper. Position the ends of the C-clamp against the rear of the caliper body and against the outer brake pad.
5. Tighten the C-clamp in order to compress the caliper piston into the caliper bore.
6. Remove the C-clamp from the caliper.
7. Use a wrench in order to hold the caliper slide pins. Remove the caliper bolts (1).
Caution: Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
8. Remove the caliper housing (2) from the caliper bracket. Support the caliper with a wire (1) in order to prevent damage to the brake hose.
9. Remove the brake pads with the insulators (1, 2).
10. Remove the 4 insulators (3) and the 2 wear indicators (2) from the 2 brake pads (1).
Inspection Procedure
1. Inspect the brake pads. If replacement is necessary, replace the disc brake pads in axle sets. Refer to Brake Pad Inspection (Testing and Inspection).
2. Clean and inspect the disc brake hardware. Replace components if necessary. Refer to Front Disc Brake Mounting and Hardware Inspection (Front Disc Brake Mounting and Hardware Inspection).
3. Clean and inspect the caliper. Repair or replace components as necessary. Refer to Brake Caliper Inspection (Testing and Inspection).
Note: Refinish or replace the rotor ONLY if the condition of the rotor requires service. DO NOT refinish the rotor if the brake pads are the only components requiring service.
4. Measure the brake rotor thickness. Refinish or replace the rotor as necessary. Refer to Brake Rotor Thickness Measurement (Brake Rotor Thickness Measurement).
5. Measure the brake rotor thickness variation. Refinish or replace the rotor as necessary. Refer to Brake Rotor Thickness Variation Measurement (Brake Rotor Thickness Variation Measurement).
6. Inspect the surface of the brake rotor. Refinish or replace the rotor as necessary. Refer to Brake Rotor Surface and Wear Inspection (Brake Rotor Surface and Wear Inspection).
7. Measure the brake rotor assembled lateral runout. Refinish or replace the rotor as necessary. Refer to Brake Rotor Assembled Lateral Runout Measurement (Brake Rotor Assembled Lateral Runout Measurement).
Installation Procedure
1. If the caliper piston is not compressed into the caliper bore, complete the following steps:
1. Place an old brake pad (2) or a block of wood against the caliper piston.
2. Install a large C-clamp over the body of the brake caliper.
3. Position the ends of the C-clamp against the rear of the caliper body and against the pad or the wood.
4. Tighten the C-clamp in order to compress the caliper piston into the caliper bore.
5. Remove the C-clamp.
2. Apply disc brake grease to both sides of the 2 outer insulators (1).
3. Ensure the disc brake grease covers the area where the outer insulators contact the inner insulators (2).
4. Install the 2 inner insulators to the 2 brake pads.
5. Install the 2 outer insulators to the 2 inner insulators.
6. Install the 2 wear indicators to the 2 brake pads.
7. Install the brake pads with the wear indicators and the insulators (1, 2) to the caliper bracket.
8. Remove the wire and install the caliper housing to the caliper bracket.
Caution: Refer to Fastener Caution (Fastener Caution).
9. Use a wrench in order to hold the caliper slide pins. Install the caliper bolts (1) and tighten to 34 Nm (25 lb ft).
10. Install the front tire and wheel assembly to the vehicle. Refer to Tire and Wheel Removal and Installation (Service and Repair).
11. Lower the vehicle.
12. With the engine OFF, gradually apply and release the brake pedal several times in order to position the caliper pistons and the brake pads.
13. Fill the master cylinder fluid reservoir. Refer to Master Cylinder Reservoir Filling (Master Cylinder Reservoir Filling).
14. Burnish the pads and the rotors. Refer to Brake Pad and Rotor Burnishing (Brake Pad and Rotor Burnishing).
