Gather tools and parts.
Ensure the vehicle is parked on a flat surface.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a wrench.
- Slide the caliper off the rotor and inspect the pads for wear.
Brake Rotors:
- Check rotors for warping by measuring thickness.
- If warped, replace with new rotors.

5. Install New Brake Pads and Rotors (if necessary)

If replacing pads and/or rotors, follow these sub-steps:
- Clean the rotor surface with brake cleaner.
- Install new rotors, ensuring they are seated properly.
- Replace brake pads, making sure they are aligned correctly in the caliper bracket.

6. Reassemble Components

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

7. Lower the Vehicle and Test

Remove jack stands and lower the vehicle.
Tighten lug nuts to the proper torque specification.
