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.
- Pull down on the front park brake cable (3).
- Remove the front park brake cable from the park brake cable connector (1).
Notice: When using a large C-clamp to compress a caliper piston
into a caliper bore of a caliper equipped with an integral park brake mechanism,
do not exceed more than 1 mm (0.039 in) of piston travel. Exceeding this amount
of piston travel will cause damage to the internal adjusting mechanism and/or
the integral park brake mechanism.
- Install a large C-clamp over
the top of the brake caliper housing and against the back of the outboard brake
pad.
• | Compress the brake caliper piston into brake caliper bore to allow the
piston enough clearance to slide the brake caliper off the brake rotor. |
- Remove the electronic brake pad wear sensor
retainer clip from the caliper.
- Carefully hold the electronic pad wear sensor wire (1) snug, and
with a small flat blade screw driver gently pry up on the electronic brake
pad wear sensor to remove it from the inner brake pad (2).
- Disconnect the electronic brake pad wear sensor wire connector.
- Remove the electronic brake pad wear sensor wire from the caliper.
- Remove the brake caliper inlet fitting bolt
to the brake caliper.
- Remove the brake hose from 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/or contamination.
- Disconnect the park brake cable bracket (2)
from the brake caliper (1).
- Disconnect the park brake cable from the park brake lever on the brake
caliper.
- Remove the lower brake caliper pin bolt.
- Rotate the brake caliper up.
- Slide the brake caliper off the upper pin bolt to remove.
Installation Procedure
- If reusing the brake caliper retainers and sleeves, clean the sleeves
using denatured alcohol, or equivalent.
- Lubricate the brake caliper pin bolts with hi temperature silicone lube.
- Install the brake caliper to the upper caliper pin bolt.
- Rotate the brake caliper (6) down over
the brake pads, onto the brake caliper bracket (5).
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 lower brake caliper pin bolt.
Tighten
Tighten the brake caliper pin bolt to 27 N·m (20 lb ft).
- Remove the plugs in the brake hose end.
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).
- Install the electronic brake pad wear sensor
wire (1) to the caliper (2).
- Connect the electronic brake pad wear sensor wire connector.
- Snap the electronic brake pad wear sensor into the inner brake pad.
- Install the electronic brake pad wear sensor retainer clip to the caliper.
- Connect the park brake cable to the park brake
lever on the brake caliper.
- Install the park brake cable bracket (2) to the brake caliper (1).
- Install the park brake cable bracket bolt.
Tighten
Tighten the park brake cable bracket bolt to 43 N·m (32 lb ft).
- Install the front park brake cable (3)
to the park brake cable connector (1).
- 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 19-20 until a
firm brake pedal apply is obtained. This will properly seat the brake caliper pistons
and brake pads.
- Install the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle.
