Wear safety gloves and goggles.

2. Lift the Vehicle

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

3. Remove Wheel

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

4. Inspect and Replace Brake Components

a. Inspect Brake Rotors

Check for warping or uneven surfaces.
If warped, proceed to replace the rotors.

b. Replace Brake Pads

Remove the caliper bolts with a socket set.
Slide the caliper off the rotor.
Replace the brake pads with new ones, ensuring correct orientation.

c. Reinstall Caliper

Reattach the caliper and torque the bolts to manufacturer specifications (usually around 20-30 ft-lbs).

5. Reassemble

Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
Lower the vehicle from the jack stands.
