Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure with jack stands.
Remove the front wheels using a socket wrench.

3. Inspect and Replace Brake Rotors

Inspection:
- Remove the caliper by unscrewing the caliper bolts and support it to avoid stress on the brake line.
- Remove the brake pads from the caliper bracket.
- Measure rotor thickness and check for warping using a dial indicator.
Replacement:
- If warped, replace rotors with OEM-spec rotors. Clean the hub surface to ensure proper installation.
- Install new rotors and torque to specifications (usually around 90-100 ft-lbs).

4. Inspect and Replace Brake Pads

Check the brake pads for wear indicators.
If worn, replace with high-quality OEM or aftermarket pads, ensuring they are the correct type for the vehicle.
Apply brake grease to the backing of the pads to prevent noise.

5. Reassemble and Lower Vehicle

Reattach the caliper and torque bolts to specifications (usually 25-30 ft-lbs).
Reinstall the wheels and torque lug nuts to the manufacturer's specifications (usually 90-100 ft-lbs).
Lower the vehicle and remove jack stands.
