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 the vehicle and suitably support. 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.
- Hand tighten 2 wheel lug nuts 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 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 caliper inlet fitting bolt
to 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 brake hose to prevent fluid
loss and contamination.
Important: When servicing the brake caliper, the first design hardware will be upgraded
to the second design hardware, with new caliper pin bolts.
- Remove the brake caliper pin bolts.
- Remove the brake caliper.
Installation Procedure
- If reusing the brake caliper pin bolts and retainers, clean the brake
caliper pin bolts and retainers using denatured alcohol, or equivalent.
- Dry the brake caliper pin bolts and retainers, using non-lubricated, filtered
air.
Important: DO NOT apply lubricant to the brake pad hardware.
- If using the first design hardware apply high temperature silicone brake lubricant
to the brake caliper pin bolts and retainers. If using the second design 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 pin bolts.
- Install the brake caliper over the brake pads 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.
Important: If installing the second design hardware kit the upper caliper pin bolt, has
a bushing as part of the assembly. The lower caliper pin, is a solid design pin bolt.
- Install the brake caliper pin bolts.
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 caliper inlet fitting bolt to the brake caliper.
Tighten
Tighten the brake caliper inlet fitting bolt to 45 N·m (33 lb ft).
- 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 14-15 until a firm
brake pedal apply is obtained. This will properly seat the brake caliper pistons
and brake pads.
- Remove the 2 wheel lug nuts retaining 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.
