Caution: Refer to Brake Dust 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 the vehicle and suitably support. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the Wheel. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
Notice: When using a large C-clamp to compress a caliper piston
into a caliper bore of a caliper equipped with an integral park brake mechanism,
do not exceed more than 1 mm (0.039 in) of piston travel. Exceeding this amount
of piston travel will cause damage to the internal adjusting mechanism and/or
the integral park brake mechanism.
- Using a large C clamp, compress the brake caliper piston into
the brake caliper bore to gain enough clearance to allow the brake caliper to pivot
off the brake caliper bracket. Compress the piston until resistance is
felt, but no more than 1 mm (0.039 in) of piston travel.
- Remove the park brake cable guide bolt
from the lower control arm.
- Remove the park brake cable bracket bolt from the caliper.
- Remove the bottom brake caliper pin bolt.
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 brake caliper body (6) upward and secure out
of the way with heavy mechanic's wire. Do NOT disconnect the hydraulic brake flexible
hose from the caliper.
- Remove the inboard (2) and outboard (3) brake pads from
the brake caliper bracket (5).
- Remove and inspect the brake pad retainers (1).
Installation Procedure
- Inspect the brake caliper bolt suspension boots for cuts, tears, or
deterioration. If damaged, replace the brake caliper pin boots.
- Inspect the brake caliper pin bolts for damage or corrosion. Replace
if damaged or corroded. Do not attempt to clean away corrosion. Corrosion
is typically caused by damaged pin boots. Refer to
Rear Disc Brake Mounting and Hardware Inspection
.
- Inspect the brake caliper piston boot for deterioration, repair or replace
the brake caliper if damaged. Refer to
Rear Brake Caliper Replacement
.
- Retract the brake caliper piston (2) into the brake caliper bore. Use
a spanner type wrench to turn the piston (2) clockwise until it bottoms
in the brake caliper bore and align the piston.
- Align the cutouts in the brake caliper piston to the alignment pins
on the brake pads.
- Lubricate the rear brake caliper bolts, retainers and slides with a thin
coat of high temperature silicone lube.
- Install
the brake pad retainers (1) into the brake caliper bracket (5).
- Install the inboard (2) and outboard (3) brake pads into
the brake caliper bracket.
- Pivot the brake caliper down over the brake pads and into the brake
caliper bracket.
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.
- Insert the lower brake caliper pin bolt.
Tighten
Tighten the brake caliper pin bolt to 27 N·m (20 lb ft).
- Install the park brake cable bracket to the caliper.
- Install the park brake cable bracket bolt.
Tighten
Tighten the park brake cable bracket to caliper bolt to 43 N·m
(32 lb ft).
- Install the park brake cable guide bolt
to the lower control arm.
Tighten
Tighten the park brake cable guide bolt to 24 N·m (18 lb ft).
- 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 repeat steps 16-17 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
.
