1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for personal protection.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure the vehicle on jack stands to ensure safety while working underneath.

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Set the wheel aside in a safe location.

4. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping using a dial indicator or visual inspection.
- If warped, remove the rotor using a socket set and replace it with a new one.
Inspect Brake Pads:
