Front Brake Kit Installation

1. Preparation: Position the vehicle on a hoist and raise to a convenient working height. Remove the wheels. If brake fluid is spilled on the paint, clean the affected area immediately with a non-aggressive cleaner (e.g., wax and grease remover).
2. Pre-build Front Calipers: Load the brake pads into the calipers with the included shims.
3. Install Caliper Pins: Install one caliper pin, then the brake pad retention clip on that pin. Press the clip down and install the second pin. The pins install from back to front. Reference provided diagrams for clip orientation.
4. Install Caliper Pin Bolt: Install the caliper pin bolt with the retention bolt fastened from the back side. Torque to 22 lb/ft (30 Nm).
5. Attach Brake Hoses: Install the provided brake hoses on the calipers using the provided banjo bolts and two copper washers per brake hose. Ensure calipers are directional and that bleeder screws point upwards when installed on the vehicle.
6. Remove Existing Calipers: Loosen the two bolts for the brake caliper. Disconnect the brake tube fitting using a proper line wrench to avoid damaging the fitting. Remove the bolt and the front brake flexible hose. Remove the caliper and hose assembly together.
7. Remove Rotor: Remove the brake disc (rotor).
8. Remove Rotor Dust Shields: Remove the three bolts securing the brake disc shield and remove the shield.
9. Install New Components: Install the supplied brake disk shields. Torque to 177 lb-in (20 Nm). Install the supplied front rotors.
10. Install Calipers: Install the caliper using the supplied bolts. Torque to 85 lb-ft (115 Nm). Torque the flexible brake hose to the caliper. Torque to 35 lb-ft (48 Nm). Use a proper line wrench. Torque the flexible brake hose to the brake tube fitting. Torque to 155 lb-in (17.5 Nm). Torque the flexible brake hose bracket bolt to the frame rail. Torque to 18 lb-ft (25 Nm).

Rear Brake Kit Installation

1. Prepare Caliper Pins: Install the bellows and rubber isolator on the caliper pins. Lubricate the pins as shown in the diagrams and note the orientation of the bellows on the pins.
2. Install Caliper Supports: Insert the pins into the caliper support. The pictured support is assembled for the left side. The blue pin should be located in the lower position on both sides of the vehicle.
3. Remove Rear Calipers: Loosen the parking brake cable adjustment nut. Disconnect the parking brake cable from the lever. Detach the parking brake cable from the bracket and position it aside. Remove the brake caliper banjo bolt and disconnect the brake hose from the brake caliper. Discard the two copper washers; the banjo bolt will be reused. Remove the two bolts holding the caliper to the caliper bracket, then remove the caliper. Remove the two caliper bracket bolts, then remove the caliper bracket.
4. Install Rear Components: Remove the brake disc. Remove and replace the brake dust shield. Torque to 106 in-lb (12 Nm). Install the supplied rear brake rotors. Install new caliper brackets. Torque to 129 lb-ft (175 Nm).
5. Install Rear Calipers: Install brake pads into the brackets with the supplied hardware. Install the supplied rear calipers with the bleeder screws facing UP. Torque to 24 lb/ft (32 Nm).
6. Attach Parking Brake Cable: Attach the parking brake cable to the lever first, then route it through the top of the bracket on both sides.
7. Attach Hydraulic Brake Line: Attach the hydraulic brake line using two new copper washers. Torque to 35 lb-ft (47.5 Nm).
8. Set Parking Brake Preload: Set the parking brake handle to the first click/position.

Brake Bleeding Procedure

Parking Brake Adjustment: While adjusting parking brake cables, check rear wheel rotation to prevent overtightening. Cables should only be tightened until rear wheels have a slight drag, ensuring they do not lock up. Release the parking brake and confirm both wheels spin freely.

With Power Bleeder:

1. Ensure the fluid reservoir is filled with new, specified brake fluid.
2. NOTICE: If brake fluid spills on paint, clean the affected area immediately with a non-aggressive cleaner (e.g., wax and grease remover).
3. NOTE: Master cylinder pressure bleeder adapter tools are available from various manufacturers. Follow the manufacturer's instructions for installation.
4. Install the bleeder adapter to the brake master cylinder reservoir and attach the bleeder tank hose to the fitting on the adapter.
5. NOTE: Ensure the bleeder tank contains enough new, specified brake fluid for the operation.
6. Open the valve on the bleeder tank and apply 207-345 kPa (30-50 psi) to the brake system.
7. Bleeding Steps: Follow the order indicated in the diagrams. For front calipers, bleed the inner bleeder screw first, then the outer bleeder screw.
8. If equipped, remove the bleeder screw cap.
9. Partially fill a clean brake fluid container with clean, specified brake fluid.
10. Submerge a hose into the brake fluid in the container and connect the other end of the hose to the bleeder screw.
11. Loosen the bleeder screw (approximately 180 degrees).
12. Leave open until clear, bubble-free brake fluid flows, then tighten the bleeder screw.
13. Disconnect the hose and tighten the bleeder screw to specification.
14. Repeat for each caliper on the vehicle (inner first, then outer).
15. If equipped, install the bleeder screw cap.

Wheel Installation

WARNING: When installing a wheel, always remove any corrosion, dirt, or foreign material from the mounting surface of the wheel, wheel hub, brake drum, or brake disc. Ensure fasteners attaching the rotor to the hub are secured and do not interfere with wheel mounting surfaces. Failure to follow these instructions may result in wheel nuts loosening, the wheel coming off during motion, loss of control, serious injury, or death.

NOTICE: Apply a thin coat of anti-seize lubricant only to the interface between the wheel pilot bore and the hub pilot. Do not allow anti-seize to contact the wheel-to-brake disc/drum mounting surface, wheel studs, wheel nuts, brake pads, or brake disc friction surfaces, as this may cause component damage.

1. Clean the mounting surface of the wheel. Apply the specified lubricant (Motorcraft® High Temperature Nickel Anti-Seize Lubricant / XL-2) to the wheel pilot bore and hub pilot.
2. NOTE: Only tighten the nuts finger tight at this stage.
3. Position the wheel and install the wheel nuts.
4. WARNING: Retighten wheel nuts within 160 km (100 mi) after wheel reinstallation. Wheels can loosen after initial tightening, potentially causing serious injury.
5. NOTICE: Failure to tighten wheel nuts in a star/cross pattern can lead to high brake disc runout, causing brake roughness, shudder, and vibration.
6. NOTE: Wheel nut torque specification applies to clean, dry wheel stud and wheel nut threads.
7. NOTE: Final tightening must be performed with the vehicle resting on its tires.
8. Tighten the wheel nuts in a star pattern. Torque: 150 lb-ft (204 Nm).
