Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working.

2. Wheel Removal

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Brake Pad and Rotor Inspection

Inspect the brake pads:
- If worn down to the metal backing, replace them.
Check the brake rotor:
- If it shows deep grooves or excessive wear, replace or resurface it.

4. Brake Pad Replacement

Remove the caliper:
- Unscrew the caliper bolts and slide the caliper off the rotor.
Remove the old brake pads:
- Pull the pads from the caliper bracket.
Install the new brake pads:
- Ensure they are oriented correctly and clipped into place.

5. Rotor Replacement or Resurfacing

If replacing the rotor:
- Remove the caliper bracket if necessary to access the rotor.
- Remove the old rotor and install the new one, ensuring proper alignment.
If resurfacing, follow manufacturer specifications for machining.

6. Reassembly

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern to the specified torque.

7. Brake Fluid Check

Check brake fluid level in the reservoir and top off as needed with the recommended fluid type (DOT 3 or DOT 4).

8. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper brake pressure before driving.
