Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, safety goggles, gloves.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if necessary for safety.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
- Inspect the brake pads for thickness; replace if they are below the manufacturer’s minimum specification (typically around 3 mm).
- If replacement is needed, remove the caliper bolts and slide the caliper off the rotor.
- Carefully remove the old brake pads from the caliper bracket.
- Apply brake grease to the backing plates of the new pads and install them in the caliper bracket.
- Reinstall the caliper over the new pads and secure it with caliper bolts to the manufacturer’s torque specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotor surface for grooves or significant wear. If damaged, replace the rotor.
- Remove rotor retaining screws if applicable, and slide the rotor off the hub.
- Clean the new rotor with brake cleaner to remove any protective oil.
- Install the new rotor on the hub and secure it if required.

5. Reassemble and Test Brake System

Replace the wheel, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the manufacturer’s specification.
Reconnect the battery if it was disconnected.
Pump the brakes to ensure the pads seat properly before driving.
