Removal Procedure
Caution: Refer to Brake Dust Caution in the Preface section.
- 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, then 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, then remove brake fluid
to the midway point before proceeding.
- Raise and suitably support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the rear tire and the wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Install a hand tightened lug nut to retain the rotor to the hub.
- Compress the caliper piston enough for
clearance. Use a C-clamp (3).
- Remove the upper caliper bolt (2).
Notice: Use care to avoid damaging pin boot when rotating caliper.
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.
- Pivot the
caliper down in order to access the pads. It is not necessary to remove the caliper.
- Remove the brake pads (2) from the caliper bracket.
- Remove the 2 pad clips (1) from the caliper bracket.
- Inspect the caliper mounting hardware for the following conditions:
- Inspect the caliper dust boot for the following conditions:
- Inspect the caliper bolts for corrosion or damage. If corrosion exists,
use new caliper bolts when installing the caliper.
Installation Procedure
- Bottom the piston into the caliper bore.
Use a C-clamp before installing new brake pads in order to compress the piston.
Use an old brake pad or wooden block across the face of the piston to avoid damage
to the piston or the caliper boot.
- Install the 2 retainers (1) to the caliper bracket.
Important: The wear sensor is on the outside pad. The sensor is positioned at the trailing
or downward edge of the pad during forward wheel rotation.
- Install the pads (2) to the caliper bracket.
Notice: Use care to avoid damaging pin boot when rotating caliper.
- Swing the caliper (3) upward in position around the pads.
- Lubricate the bolt and the bolt boot. Use silicone grease.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the upper caliper bolt (2).
Tighten
Tighten the caliper bolt to 44 N·m (32 lb ft).
- Remove the wheel lug nut retaining the rotor to the hub.
- Install the rear tire and the wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels. Align the
previous marks on the wheel, hub and bearing.
- 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 repeat steps 10 and 11 until a firm brake pedal
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
