Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel Assembly

Sub-steps:
1. Loosen the lug nuts on the affected wheel while the vehicle is on the ground.
2. Jack up the vehicle and support it securely on jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Sub-steps:
1. Remove the brake caliper by unbolting it from the bracket (use a socket wrench).
2. Suspend the caliper using a bungee cord to avoid stress on the brake line.
3. Remove the brake pads from the caliper bracket.
4. Measure the thickness of the brake rotors using a caliper; replace if below minimum thickness.
5. If rotors are warped, replace them. Clean the mounting surface on the hub before installation.
6. Install new brake pads and ensure they are properly seated in the caliper bracket.
7. Reinstall the brake caliper over the new pads and secure it with the bolts to the manufacturer’s torque specifications.

4. Reassemble Wheel Assembly

Sub-steps:
1. Reinstall the wheel onto the hub.
2. Hand-tighten the lug nuts before lowering the vehicle.
3. Lower the vehicle to the ground and then use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
