Front Brake Caliper Replacement Bendix Rail Slider
Removal Procedure
- Apply the parking brake.
- Block the wheels.
- Tilt the cab. Refer to
Cab Tilting
in General Information.
- Remove about two-thirds of the brake fluid from the master cylinder
reservoir.
• | Do not completely drain the master cylinder reservoir. |
• | Drain the fluid from the brake caliper bleeder valve. |
• | Drain the fluid into a suitable container. Discard the fluid. |
- Raise and support the vehicle. 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.
- Remove the brake caliper retainer screw (1).
- Remove the brake caliper retainer (3) and the brake caliper
spring (2) using a brass punch.
- Compress the pistons,
using a C-clamp between the inner brake caliper housing and the outer brake
pad.
- If C-clamp is not available.
Use screwdrivers in order to pry between the outer brake caliper housing and
the outer brake pad.
- While compressing the pistons, watch the reservoir for possible
brake fluid overflow. The inner brake pad may stay on the brake caliper mounting
plate (Bendix® Caliper).
- Remove the two bolts from the brake caliper flexible hose mounting
bracket.
- Disconnect the brake hose from the brake calipers.
- Cap or tape the brake hose fitting in order to prevent contamination.
Important:
• | Clean the area around the brake hose on the brake caliper with
denatured alcohol or other suitable solvent. |
• | Cap or tape the fitting in order to prevent dirt from entering
the brake hose. |
- Remove the brake caliper.
Installation Procedure
- Clean the support rail
surfaces of the brake caliper with a wire brush. File smooth any deep nicks
or gouges.
- Clean the support rail surfaces of the brake caliper mounting
plate with a wire brush. File smooth any deep nicks or gouges.
- Apply a thin coat of brake caliper lubricant to the brake caliper
mounting plate support rail surfaces.
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.
- Loosely assemble the
brake hose nut to the brake caliper.
Tighten
• | Tighten the brake hose nut to 19 N·m (14 lb ft). |
• | Tighten the brake hose bracket bolts to 32 N·m (24 lb ft). |
- Install the brake caliper.
- Inspect for brake caliper/mounting plate wear. Refer to
Brake Caliper/Mounting Plate Wear Adjustment
.
- Apply a thin coat of brake caliper lubricant to the brake caliper
retainer and the brake caliper spring.
- Tap the brake caliper retainer and brake caliper spring into place using
a brass punch and a light weight hammer. The hose in the brake caliper
retainer should line up with the threaded hole in the brake caliper
mounting plate.
Important:
• | The brake caliper retainer bolt boss must fit in the circular
hole in the brake caliper retainer. |
• | Do not reuse the brake caliper retainer bolt . |
- Install NEW brake caliper retainer bolt (1).
Tighten
Tighten the brake caliper retainer bolt to 40 N·m (29 lb ft).
- Lower the cab. Refer to
Cab Tilting
in General Information.
- Bleed the hydraulic brake system. Refer to
Hydraulic Brake System Bleeding
in Hydraulic Brakes.
Important: Check the fluid level in the master cylinder reservoir after pumping
the brake pedal.
- Pump the brake pedal several times in order to ensure that the pedal
is firm and the brake pads are seated.
- Inspect the brake fluid level in the master cylinder. Refer to
Master Cylinder Reservoir Filling
in Hydraulic
Brakes.
- Install the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle. Refer to
Lifting and Jacking the Vehicle
.
- Remove the wheel blocks.
