Front Brake Caliper Replacement Second Design
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 and retainers,
wipe the old grease from the brake caliper pin bolts and retainers 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 pin bolts.
- Install the brake caliper (2)
over the brake pads into the brake caliper bracket (3).
Important: The upper caliper pin, has a bushing as part of the assembly. The lower
caliper pin, a solid design pin bolt.
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.
- 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 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.

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.

of the brake caliper with the C-clamp ends against the rear of the
caliper body and against the outer brake pad.

- 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: 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 (1, 2).
- 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.
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.
