Front Brake Caliper Replacement without J55
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.
- 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 hose to caliper bolt attaching
the brake hose 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 pipe to prevent fluid loss
and contamination.
Important: Note the location of the caliper pin
bolts. The upper caliper pin bolt, has a bushing as part of the assembly. The lower
caliper pin bolt, is a solid design pin bolt.
- Remove the caliper pin bolts (1).
Note the location of the caliper pin bolts. The upper caliper pin, has a bushing
as part of the assembly. The lower caliper pin bolt , is a solid design pin bolt
.
- Remove the caliper (2) from the rotor and the caliper bracket (3).
- Inspect the caliper 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 a thin coat of 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 (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, has a bushing as part
of the assembly. The lower caliper pin, is a solid design pin bolt.
- Install the caliper pin bolts (1). The upper caliper pin bolt, has a
bushing as part of the assembly. The lower caliper pin bolt, a solid design pin bolt.
Ensure that the bolt boots fit securely around the caliper pin bolts. If the boots
are damaged, they must be replaced.
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 rear brake hose to caliper 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 9-10 until a firm
brake pedal 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.
