Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Sub-steps:
1. Loosen the lug nuts on the wheel slightly while the vehicle is on the ground.
2. Lift the vehicle using a jack and securely place jack stands under the frame.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, C-clamp or brake caliper tool
Sub-steps:
1. Remove the brake caliper by unbolting it from the caliper bracket.
2. Slide the caliper off the rotor and suspend it with a wire or bungee to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any damage or sticking issues.
5. If worn, install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Torque wrench
Sub-steps:
1. If the rotors are scored or warped, unbolt them from the hub assembly.
2. Clean the hub surface with a wire brush.
3. Install the new rotors, if needed, and torque to the manufacturer's specifications.

5. Reassemble Brake Components

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the brake caliper over the new pads and rotor.
2. Torque the caliper bolts to the manufacturer's specifications.
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Tools Required: None
Sub-steps:
1. Lower the vehicle back to the ground.
2. Torque the lug nuts to the manufacturer’s specifications in a star pattern.
3. Press the brake pedal several times to seat the brake pads properly.
