Caution: Refer to Brake Dust Caution in the Preface section.
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Removal Procedure
- Inspect the fluid level in the brake master cylinder reservoir.
- If the brake fluid level is midway between the maximum-full point
and the minimum allowable level, no brake fluid needs to be removed from the reservoir
before proceeding.
- 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.
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Install and firmly hand tighten 2
wheel nuts to opposite wheel studs in order to retain the rotor to the hub.
- Install a large C-clamp over the body of the brake caliper with the C-clamp
ends against the rear of the caliper body and against the outboard brake pad.
- Tighten the C-clamp evenly until the caliper piston is compressed into
the caliper bore enough to allow the caliper to slide past the brake rotor.
- Remove the C-clamp from the caliper.
- Fully loosen the caliper bolts (1, 4) from the steering knuckle (3).
Notice: 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.
- Without disconnecting the hydraulic brake flexible hose, remove
the caliper assembly (2) from the steering knuckle. Support the caliper with
heavy mechanic's wire (1), or equivalent.
- Remove the brake pads from the caliper.
- Remove the disc brake caliper bolts (1)
from the caliper assembly (3).
- Inspect the caliper bolts (1) for rust, corrosion and/or damage.
- If the bolts are rusty, corroded, and/or damaged, replace the bolts (1)
and replace the bushings (2). Refer to
Disc Brake Hardware Replacement
.
Installation Procedure
- Install a large C-clamp (2) over the body of the brake caliper (1),
with the C-clamp ends against the rear of the caliper body and against an old inboard
brake pad or a wood block installed against the caliper piston.
- Tighten the C-clamp (2) evenly until the caliper piston is compressed
completely into the caliper bore.
- Remove the C-clamp and the old brake pad or wood block from the caliper.
- Lubricate the caliper bushings and install the caliper bolts to the caliper.
Refer to
Disc Brake Hardware Replacement
.
Important: The outer brake pad must be mounted with the leading edge of the wear sensor
facing the brake rotor during forward wheel rotation, or at the top of the pad when
installed in vehicle position.
- Install the brake pads to the caliper.
- Thoroughly clean the brake pad mating surface on the steering knuckle
of any surface debris and/or corrosion.
- Apply a thin layer of high temperature silicone brake lubricant to the
brake pad mating surface on the steering knuckle.
- Install the caliper assembly (2) to the steering knuckle (3).
Notice: Refer to Fastener Notice in the Preface section.
- Tighten the caliper bolts (1, 4) to the steering knuckle (3).
Tighten
Tighten the bolts to 51 N·m (38 lb ft).
- Remove the wheel nuts securing the rotor to the hub.
- Install the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle.
- With the engine OFF, gradually apply the brake pedal to approximately 2/3
of its travel distance.
- Slowly release the brake pedal.
- 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.
- Fill the brake master cylinder reservoir to the proper level. Refer to
Master Cylinder Reservoir Filling
in Hydraulic Brakes.
- Burnish the pads and rotors. Refer to
Brake Pad and Rotor Burnishing
.
