Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Lift Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, as needed.
Secure the vehicle with jack stands.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Store lug nuts in a safe place.

4. Inspect and Replace Brake Rotors

Inspect: Check rotors for warping using a dial indicator.
Replace (if warped):
1. Remove the brake caliper by unbolting it from the mounting bracket.
2. Remove the brake pads.
3. Unbolt the rotor from the hub (if applicable) and replace with a new rotor.
4. Clean the hub surface before installing the new rotor.
5. Reinstall the caliper and brake pads.

5. Inspect and Replace Brake Pads

If brake pads are worn unevenly, remove and replace them:
1. Unbolt the caliper and slide it off the rotor.
2. Remove old pads from their brackets.
3. Install new pads, ensuring they are seated properly.
4. Reattach the caliper.

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground.
Torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).
