Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Lift the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Carefully take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads. If they are worn down to the indicator, replace them.
Replace:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated in the bracket.
- Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specification.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect: Check rotors for any grooves or significant wear.
Replace (if necessary):
- Remove the caliper bracket bolts and take off the bracket.
- Slide the rotor off the hub (may require tapping with a mallet if stuck).
- Install new rotors, ensuring they are clean and free of oil or grease.
- Reattach the caliper bracket and tighten the bolts to the manufacturer's torque specification.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts to the specified torque.
