Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety gloves and goggles.

2. Lift Vehicle

Tools Required: Floor jack, jack stands
Sub-steps:
1. Use a floor jack to lift the front of the vehicle.
2. Secure the vehicle with jack stands for safety.

3. Remove Wheel

Tools Required: Lug wrench
Sub-steps:
1. Loosen the lug nuts on the front wheel.
2. Remove the lug nuts and take off the wheel.

4. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the caliper mounting bolts and carefully detach the caliper from the rotor.
2. Suspend the caliper using a bungee cord or similar to avoid strain on the brake line.
3. Remove the rotor by unscrewing any retaining screws if equipped and sliding it off the hub.
4. Inspect the rotor for warping or uneven wear. If damaged, replace with new rotors.
5. Torque the new rotor retaining screws to the manufacturer's specifications.
