Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use jack stands to securely lift the vehicle if necessary.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle with a jack and secure with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Check for wear indicators; replace pads if less than 3mm thickness is remaining.
- If pads are worn unevenly, assess caliper function.
Brake Rotors:
- Inspect for scoring or warping; replace if grooves are deep or surface is uneven.
- Measure rotor thickness; replace if below manufacturer specifications.

4. Replace Brake Pads and/or Rotors

If replacing brake pads:
- Remove the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor and support it with a hanger.
- Remove old pads and install new pads, ensuring they are properly seated.
If replacing rotors:
- Remove the old rotor from the hub.
- Install the new rotor, ensuring it is flush against the hub.

5. Reassemble and Test

Reinstall the caliper over the new pads or rotor.
Tighten caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and fully tighten lug nuts in a crisscross pattern.
