Solution

1. Preparation

Gather necessary 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 lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Check the thickness of the brake pads. If less than 3mm, replace them.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new brake pads, ensuring they are seated properly.
- Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check the rotor surface for deep grooves or scoring. If damaged, they need replacement.
Replace Rotors:
- Remove the caliper bracket if necessary, and slide the rotor off the hub.
- Clean the hub surface and install a new rotor, ensuring it is seated correctly.
- Reinstall the caliper bracket and tighten bolts to the specified torque.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 100-120 ft-lbs).
Test the brakes by pressing the pedal a few times to seat the pads.
