Solution

1. Preparation

Gather tools and materials.
Ensure vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and glasses.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

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

4. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it with a bungee cord or strap (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Check the caliper bracket and clean any debris or rust.
- Install new brake pads, ensuring they are properly seated.

5. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Measure the rotor thickness; if below minimum specification, replace the rotor.
- To remove the rotor, remove the retaining screws (if applicable) and slide the rotor off the hub.
- Install new rotors, ensuring they are clean and free of oil.
- Torque the rotor retaining screws to the manufacturer’s specifications.

6. Reassemble

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the proper specification.

7. Final Checks

Pump the brake pedal until it feels firm to ensure proper caliper engagement.
Check brake fluid levels and top off if necessary.
