Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Check the brake pads for thickness and wear indicators.
If worn, remove the caliper bolts and slide the caliper off the rotor.
Remove old brake pads and install new ones, ensuring they are oriented correctly.
Reinstall the caliper and torque bolts to manufacturer's specifications (usually around 25-35 ft-lbs).

4. Inspect and Resurface/Replace Brake Rotors

Check the rotor surface for grooves and warping using a runout gauge.
If warped beyond specification, remove the rotors by unscrewing the retaining screws (if applicable) and sliding them off the hub.
Either resurface the rotors (if within specifications) or replace with new rotors, ensuring they are properly torqued (usually around 70-90 ft-lbs).

5. Reassemble and Reinstall Wheel

Reinstall the wheel, ensuring that the lug nuts are hand-tight.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the specified torque (usually around 76-85 ft-lbs).
Remove jack stands and lower the vehicle completely.
