Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off and hang it using a bungee cord to avoid straining the brake line.
- Inspect the brake pads for thickness; replace if they are worn down to less than 1/8 inch.
Brake Rotors:
- Check the surface of the rotors for grooves or scoring.
- If damaged, remove the rotor by unscrewing any retaining screws, if applicable, and slide it off the hub.
- Measure the rotor thickness with a micrometer; replace if below the manufacturer's minimum specification.

4. Replace Brake Pads and Rotors (if necessary)

Install new brake pads with the correct orientation and ensure they fit snugly.
If replacing rotors, install new rotors by sliding them onto the hub and reattaching any retaining screws.

5. Reassemble and Test

Reattach the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and torque the lug nuts in a star pattern to ensure even pressure.
Lower the vehicle and perform a brake fluid check; top off if necessary.
