Front Disc Brake Pads Replacement J55
Caution: Two different designs
of the front brake rotors and front brake pads are used on this vehicle.
Do NOT interchange first design and second design parts, or a loss of braking and
personal injury could occur.
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.
- Mark the relationship of the wheel to the axle flange.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- 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 outer brake pads.
- Tighten the C-clamp until the caliper pistons are compressed into the
caliper bore enough to allow the caliper to slide past the brake rotor.
- Remove the C-clamp from the brake caliper.
- Remove the brake caliper pin bolts (1).
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 upward and secure out
of the way with heavy mechanic's wire or equivalent. Do NOT disconnect the hydraulic
brake flexible hose from the caliper.
- 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 inner brake pad or a wood block (2) installed
against the caliper pistons.
- Tighten the C-clamp until the caliper pistons are compressed completely
into the caliper bore.
- Remove the C-clamp and the old brake pad or wood block from the caliper.
- Remove the inboard and outboard brake pads from the brake caliper mounting
bracket.
- Remove and inspect the brake pad retainers.
Installation Procedure
- Inspect the brake caliper bolt suspension boots for cuts, tears, or deterioration.
If damaged, replace the pin boots. Refer to
Front Disc Brake Hardware Replacement
.
- 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
Front Disc Brake Hardware Replacement
.
- Inspect the piston boot for deterioration, replace if damaged. Refer
to
Front Brake Caliper Overhaul
.
- Install the brake pad retainers into the brake caliper
bracket.
- Pivot the brake caliper down over the brake pads and into the brake caliper
bracket.
- Apply a thin coat of high temperature silicone lube to the front brake
caliper pin bolts.
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 (1).
Tighten
Tighten the brake caliper pin bolts to 113 N·m
(83 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 10-11 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
.
