Solution

1. Preparation

Gather tools: socket set, jack and jack stands, brake cleaner, and torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

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.
Completely remove the lug nuts and take off the wheel.

3. Brake Pad and Rotor Inspection

Inspect Brake Pads:
- Remove the caliper bolts using the socket set.
- Slide the caliper off the rotor and support it (do not let it hang by the brake line).
- Check the brake pads for wear; if they are below the minimum thickness, replace them.
Inspect Brake Rotors:
- Check for grooves or scoring on the rotor surface.
- If the rotor is damaged or worn beyond specification, it should be resurfaced or replaced.

4. Replacement

Replace Brake Pads:
- If necessary, remove the old pads and install new brake pads, ensuring they are properly aligned.
Replace or Resurface Rotors:
- If replacing rotors, remove the old rotor by unscrewing it from the hub.
- Install new rotors, ensuring they are properly seated and torqued to manufacturer specifications (usually around 80-100 ft-lbs).

5. Reassembly

Reattach the brake caliper over the new pads or rotor.
Tighten caliper bolts to the specified torque.
Reinstall the wheel, hand-tighten the lug nuts, lower the vehicle, and then fully tighten the lug nuts in a crisscross pattern to ensure even pressure.

6. Final Checks

Pump the brake pedal several times to seat the pads.
Check brake fluid level and add fluid if necessary.
