Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety goggles and gloves.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and carefully take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and hang it using a bungee cord to avoid stress on the brake line.
- Inspect the brake pads for wear; replace if they are worn down to the indicator.
Brake Rotors:
- Check the surface of the rotors for grooves or scoring.
- Use a micrometer to measure rotor thickness; replace if below manufacturer's specifications.
- If the rotors are within specifications but damaged, consider resurfacing.

4. Replace Components

If brake pads are worn, replace them:
- Remove the old pads from the caliper bracket.
- Install the new brake pads, ensuring they are properly seated.
If rotors are damaged or below thickness specifications, replace them:
- Remove the caliper bracket and the rotor from the hub.
- Install the new rotor, ensuring it is properly aligned.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and torque the lug nuts in a star pattern to the specified torque.
Lower the vehicle and pump the brakes to ensure proper pad seating.
