Front brakes

Hi,

Replacing front brakes isn't too hard to do. You can expect to get approximately 25,000 miles from a set of pads, but that is based on the driver.

First, here is a link that shows how to replace brakes and rotors in general. You can use this as a guide.

Removal Procedure

Warning: Refer to Brake Dust Warning See: Brakes and Traction Control > Technician Safety Information > Brake Dust Warning.

Note: Always replace disc brake pads in axle sets.

1. Inspect the fluid level in the master cylinder reservoir.

2. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluids needs to be removed from the reservoir before proceeding.

3. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.

4. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle See: Vehicle Lifting > Procedures > Lifting and Jacking the Vehicle

5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation See: Wheels and Tires > Removal and Replacement > Tire and Wheel Removal and Installation.

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.

6. Remove the brake caliper lower guide pin bolt (1).

7. Without disconnecting the hydraulic brake flexible hose, pivot the caliper upward and secure the caliper with heavy mechanics wire, or equivalent.

8. Remove the inboard brake pad (1) from the caliper mounting bracket (3).
Note the location of the brake pad audible wear sensor.

9. Remove the outboard brake pad (2) from the caliper mounting bracket (3).

10. Remove the brake pad retainers (1) from the caliper bracket (2).

11. Inspect the disc brake mounting and hardware. Refer to Front Disc Brake Mounting and Hardware Inspection See: Disc Brake System > Component Tests and General Diagnostics > Front Disc Brake Mounting and Hardware Inspection.

Installation Procedure

pic 4

1. Install a large C-clamp (1) over the body of the brake caliper (3), with the C-clamp ends against the rear of the caliper body and against an old inboard brake pad (2) or a wood block installed against the caliper pistons.

2. Tighten the C-clamp evenly until the caliper piston is compressed completely into the caliper bore.

3. Remove the C-clamp and the old brake pad or wood block from the caliper.

4. Install the brake pad retainers (1) to the caliper bracket (2).

pic 6

Note: The wear sensor equipped disc brake pad must be mounted inboard of the rotor with the leading edge of the sensor facing the brake rotor during forward wheel rotation, or at the top of the pad when installed in vehicle position.

5. Install the brake pads (1, 2) to the caliper bracket (3).

6. Remove the support, and rotate the brake caliper into position over the disc brake pads and to the caliper mounting bracket.

pic 7

Caution: Refer to Fastener Caution See: Vehicle > Technician Safety Information > Fastener Caution.

7. Install the lower brake caliper guide pin bolt (1) and tighten to 28 Nm (21 lb ft).

8. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation See: Wheels and Tires > Removal and Replacement > Tire and Wheel Removal and Installation.

9. Lower the vehicle.

10. With the engine OFF, gradually apply the brake pedal approximately 2/3 of its travel distance.

11. Slowly release the brake pedal.

12. Wait 15 seconds, then gradually apply the brake pedal approximately 2/3 of its travel distance again until a firm brake pedal apply is obtained. This will properly seat the brake caliper pistons and brake pads.

13. Fill the master cylinder reservoir to the proper level. Refer to Master Cylinder Reservoir Filling See: Brake Master Cylinder > Procedures > Master Cylinder Reservoir Filling.

14. Burnish the pads and rotors. Refer to Brake Pad and Rotor Burnishing See: Brake Pad > Procedures > Brake Pad and Rotor Burnishing.

Special Tools

* CH-41013 - Rotor Surfacing Kit

* CH-42450-A - Wheel Hub Resurfacing Kit

For equivalent regional tools, refer to Special Tools See: Disc Brake System > Electrical / Mechanical Repair.

Warning:
Refer to Brake Dust Warning See: Brakes and Traction Control > Technician Safety Information > Brake Dust Warning.

Removal Procedure

Caution:
Refer to Vehicle Lifting and Jacking Caution See: Vehicle Lifting > Technician Safety Information > Vehicle Lifting and Jacking Caution.

1. Raise and support the vehicle.

2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation See: Wheels and Tires > Removal and Replacement > Tire and Wheel Removal and Installation.

3. Remove the brake rotor screw (1).

pic 9

4. Install a C-clamp over the body of the brake caliper, with the C-clamp ends against the rear of the caliper body and the outboard disc brake pad.

5. Tighten the C-clamp until the caliper piston is compressed into the caliper bore enough to allow the caliper to slide past the brake rotor.

6. Remove the C-clamp.

7. Remove the brake caliper and the caliper mounting bracket as an assembly from the steering knuckle and support the assembly with heavy mechanics wire or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose. Refer to Front Brake Caliper Bracket Replacement See: Brake Caliper > Removal and Replacement > Front Brake Caliper Bracket Replacement.

8. Remove the brake rotor (1) from the hub flange (2).

Installation Procedure

pic 11

Note:
Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral runout (LRO) of the brake rotor, which could lead to brake pulsation.

1. Using the CH-42450-A - wheel hub resurfacing kit, thoroughly clean any rust or corrosion from the mating surface of the hub flange (1).

2. Using the CH-41013 - rotor resurfacing kit, thoroughly clean any rust or corrosion from the mating surface and mounting surface of the brake rotor (2).

3. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.

4. Install the brake rotor (1) to the hub/axle flange.

Caution:
Refer to Fastener Caution See: Vehicle > Technician Safety Information > Fastener Caution.

5. Install the brake rotor screw (2) and tighten to 4 Nm (35 lb in).

6. Remove the support, and install the brake caliper and the brake caliper bracket as an assembly to the steering knuckle and install the brake caliper bracket bolts (1). Refer to Front Brake Caliper Bracket Replacement See: Brake Caliper > Removal and Replacement > Front Brake Caliper Bracket Replacement.

7. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation See: Wheels and Tires > Removal and Replacement > Tire and Wheel Removal and Installation.

8. Lower the vehicle.

9. If the brake rotor was refinished or replaced, or if new brake pads were installed, burnish the pads and rotors. Refer to Brake Pad and Rotor Burnishing See: Brake Pad > Procedures > Brake Pad and Rotor Burnishing.
