Caution: Refer to Brake Dust Caution in the Preface section.
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice 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.
- Mark the relationship of wheel to the axle flange.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in
Tires and Wheels.
- Install and hand tighten 2 wheel lug nuts to retain the rotor to the hub.
- Lift the electronic brake wear sensor retainer
clip.
- Remove the electronic brake wear sensor wire (1) from under the retainer
clip.
- Carefully pulling up on the electronic brake wear sensor wire and with
a small screw driver push the retaining clip inward and remove the electronic
brake wear sensor from the inner brake pad.
- Disconnect the electronic brake wear sensor connector.
- Remove the electronic brake wear sensor form the caliper.
- 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 pad.
- 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.
- Remove the C-clamp from the caliper.
- Remove the brake hose to caliper bolt from the
brake caliper.
- Remove and discard the two copper brake hose gaskets. These gaskets may
be stuck to the brake caliper and/or the brake hose end.
- Plug the opening in the brake caliper and hose to prevent fluid loss and
contamination.
Important: The upper caliper pin bolt, has a bushing as part of the bolt. The lower caliper
pin bolt, is of a solid design.
- Remove the caliper pin bolts (1). Note the
location of the caliper pin bolts.
- Remove the caliper (2) from the caliper bracket (3).
- Inspect the caliper pin bolt boots in the caliper bracket for the following
conditions:
Installation Procedure
- If reusing the brake caliper pin bolts, wipe the old grease from the brake
caliper pin bolts with a clean shop towel.
Important: DO NOT apply lubricant to the brake pad hardware.
- Apply NIGLUBE® grease to the brake caliper pin bolts. It is not necessary
to apply lubricant to the brake pad hardware or the threads of the caliper pin
bolts.
- Install the brake caliper (2) over the
brake pads into the brake caliper bracket (3).
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.
Important: The upper caliper pin bolt, has a bushing as part of the bolt. The lower caliper
pin bolt, is of a solid design.
- Install the caliper pin bolts (1).
Tighten
Tighten the brake caliper pin bolts to 85 N·m (63 lb ft).
Important: Install NEW copper brake hose gaskets.
- Assemble the brake hose bolt and the NEW copper brake hose gaskets to the brake
hose.
- Install the brake hose to caliper bolt to the
brake caliper.
Tighten
Tighten the brake hose to caliper bolt to 45 N·m (33 lb ft).
- Install the electronic brake wear sensor wiring (1) to the caliper.
- Install the electronic brake wear sensor to the caliper.
- Connect the electronic brake wear sensor connector.
- Insert the electronic brake wear sensor into the inn brake pad.
- Lift the electronic brake wear sensor retainer clip and install the wire
under the clip.
- Bleed the brake system. Refer to
Hydraulic Brake System Bleeding
in Hydraulic Brakes.
- 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 13-14 until a firm
brake pedal is obtained. This will properly seat the brake caliper pistons and brake
pads.
- Remove the two wheel lug nuts retaining the brake 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.
