Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Wheel Removal

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheels to access the brake components.

3. Brake Inspection

Inspect the brake pads:
- If they are worn below the manufacturer's specifications, replace them.
- Note the material type; consider switching to low-dust pads if necessary.
Check the brake rotors:
- If they are scored or worn unevenly, resurface or replace them.

4. Brake Pad Replacement

Remove the caliper bolts using a socket set and slide the caliper off.
Remove the old brake pads and install new ones in the reverse order.
Use a torque wrench to tighten caliper bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).

5. Reassemble and Test

Reattach the wheel, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the correct specification (typically 80-100 ft-lbs).
Pump the brake pedal a few times to ensure brake pads are seated properly.
