Front Brake Caliper Replacement First Design
Removal Procedure
- Remove 2/3 of brake fluid from master cylinder.
- Raise the vehicle and suitably support. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the wheel and tire assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Compress the caliper piston
into caliper bore to allow the piston enough clearance to pass by the bosses
on the brake pads.
• | Install a large C-clamp over top of the caliper housing and against
back of the outboard pad. |
• | Slowly tighten C-clamp until piston is pushed into caliper bore
far enough to slide caliper off rotor. |
- If the caliper is to
be removed for repair, remove the bolt attaching the inlet fitting to the
caliper, and plug the opening in the caliper and/or pipe to prevent
fluid loss and contamination.
- Remove the caliper pin
bolts.
- Remove the caliper.
Installation Procedure
- Install the caliper over
the brake pads into the caliper anchor 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.
- Install the caliper pin bolts.
Tighten
Tighten the caliper pin bolts to 85 N·m (63 lb ft).
- Install the brake hose
inlet fitting to the caliper.
Tighten
Tighten the brake hose fitting bolt to 45 N·m (33 lb ft).
- Bleed the brake system. Refer to
Hydraulic Brake System Bleeding
.
- Install the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle.
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:
• | Replace any damaged the caliper bolt boots. |
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.
