Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, caliper gauge, brake cleaner, and safety goggles.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Lift Vehicle

Use a lug wrench to loosen lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect Brake Components

Brake Pads: Remove the brake caliper bolts with a socket set. Carefully slide the caliper off the rotor and check the brake pads for uneven wear.
Brake Rotors: Inspect the surface of the rotors for grooves or uneven wear. Measure rotor thickness with a micrometer to ensure it’s within specification.
Calipers: Check the caliper slides for rust or dirt that may prevent smooth operation. Clean and lubricate as necessary.

4. Replace Components if Necessary

If pads or rotors are worn beyond specifications, replace them:
- Remove old pads and install new ones ensuring they are seated properly.
- For rotors, remove the old rotor and install a new one, ensuring to torque the bolts to manufacturer specifications (usually around 75-90 ft-lbs).

5. Reassemble

Reinstall the brake caliper and tighten the caliper bolts to the manufacturer’s torque specifications.
Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle

Carefully lower the vehicle from the jack stands and fully tighten the lug nuts to the specified torque.
