Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.
Gather the following tools: jack, jack stands, lug wrench, torque wrench, brake cleaner, and safety glasses.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Inspect the brake pads for thickness and uneven wear.
- If worn below the manufacturer's specification, replace the brake pads.
- Use brake cleaner to clean the caliper and mounting surfaces.
Brake Rotors:
- Inspect the rotors for grooves, cracks, or warping.
- If damaged or below the minimum thickness, replace the rotors.
- If the rotors are salvageable, resurface them according to manufacturer specifications.

4. Reassemble Braking System

Install new or resurfaced rotors onto the hub.
Install new brake pads into the caliper bracket, ensuring they are correctly positioned.
Reinstall the caliper over the new brake pads and torque bolts to manufacturer specifications.

5. Reinstall Wheel and Final Checks

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and fully tighten the lug nuts in a star pattern to the manufacturer's torque specification.
Reconnect the battery and check brake fluid level, topping off if necessary.
