Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, brake cleaner, safety glasses, gloves.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.
Allow the vehicle to cool down if it has been recently driven.

2. Raise the Vehicle

Use a jack to raise the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure safety.

3. Remove Wheel

Use a lug wrench to remove the lug nuts from the wheel being serviced.
Remove the wheel and set it aside.

4. Inspect Brake Components

Brake Pads:
- Check the thickness of the brake pads. Replace if they are below manufacturer's specifications (typically less than 3 mm).
Brake Rotors:
- Inspect the brake rotors for any grooves or scoring. Measure rotor thickness with a micrometer; replace if below specifications.
Calipers:
- Ensure calipers are not sticking by moving them back and forth. Lubricate sliding pins if needed.

5. Replace Components (if needed)

Brake Pads:
- Remove the old brake pads by retracting the caliper piston using a brake tool.
- Install new brake pads ensuring they are properly seated in the caliper bracket.
Brake Rotors:
- If replacing, remove the old rotor by unscrewing retaining screws (if applicable) and slide the new rotor into place.
- Clean the rotor surface with brake cleaner to remove any protective oil.

6. Reassemble

Reattach the caliper over the new brake pads and rotor.
Tighten caliper bolts to manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Final Checks

Lower the vehicle and remove jack stands.
Torque the lug nuts to the specified torque values in a crisscross pattern.
Reconnect the battery.
