Removal Procedure
Caution: Do not move the vehicle until a firm brake pedal is obtained. Failure
to obtain a firm pedal before moving vehicle may result in personal injury.
- Remove one-third of the brake fluid from the master cylinder.
- Raise and suitably support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Mark the relationship of the wheel to the hub.
- Remove the front tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires
and Wheels.
- Install a large C-clamp
(2) over the top of the brake caliper and against the back of the outboard
brake pad.
- Tighten the C-clamp until the caliper piston is pushed into the
caliper bore enough to slide the caliper off the rotor.
Notice: Do not allow calipers to hang from the flexible hoses. Doing so can
damage the hoses.
- If you remove the caliper
from the vehicle for unit repair (overhaul), then remove the brake hose bolt
that attaches the inlet fitting. If only the brake pads are being replaced,
do not disconnect the inlet fitting.
- Plug the openings in the caliper housing (3) and the pipe in order
to prevent brake fluid loss and contamination.
- Remove the caliper bolts
(3).
- Remove the caliper housing (1) from the rotor and the caliper
bracket (2).
- Inspect the bolt boots for the following conditions:
• | Replace the bolt boots if damage exists. |
- Inspect the piston boot for the following conditions:
- Inspect the bolt boots in the caliper bracket for the following
conditions:
- Inspect the caliper bolts
(1) for corrosion or damage. If corrosion is found, use new parts, including
bushings, when installing the caliper. Do not attempt to
polish away corrosion.
Installation Procedure
- Install the caliper housing
(1) over the rotor and the caliper bracket (2). Ensure that the bushings are
in place.
- Lubricate the caliper
bolts (1). Use silicone grease. Do not lubricate the threads.
- Lubricate the two bolt
boots (5) in the caliper bracket (6). Use silicone grease.
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
bolts (1). Use a screwdriver in order to push the bolt boot over the shoulder
of the caliper bolt. Ensure that the bolt boot fits securely in the
groove of the pin bolt.
Tighten
Tighten the caliper bolts to 85 N·m (63 lb ft).
Important: Replace the copper gaskets.
- Install the brake hose bolt, if removed.
Tighten
Tighten the brake hose bolt to 54 N·m(40 lb ft).
- Remove the wheel nuts securing the rotor to the hub.
- Install the front tire and the wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle.
- Fill the master cylinder to the proper level with clean brake
fluid. Refer to
Master Cylinder Reservoir Filling
in Hydraulic Brakes.
- Bleed the caliper if the inlet fitting was removed. Refer to
Hydraulic Brake System Bleeding
in Hydraulic Brakes.
- Firmly apply the brake pedal three times after bleeding, if necessary.
- Inspect the hydraulic brake system for brake fluid leaks. Refer
to
Brake Fluid Leak
in Hydraulic
Brakes.
