Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Park the vehicle on a level surface and set the parking brake.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Sub-steps:
- Loosen the lug nuts slightly while the vehicle is still on the ground.
- Use the jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Sub-steps:
- Remove the caliper bolts using the socket set.
- Carefully slide the caliper off the rotor; support it with a bungee cord or similar device to avoid strain on the brake line.
- Inspect the brake pads for wear; replace if less than 3mm thick.
- Check the rotor surface for scoring or warping; machine or replace if necessary.

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
- If replacing pads, remove old pads and install new ones, ensuring proper orientation.
- If the rotor is damaged, remove the old rotor and install the new rotor, ensuring the bolts are torqued to manufacturer specifications (usually around 80-100 ft-lbs).
- Reinstall the caliper over the new pads/rotor, ensuring it moves freely and is secured with the original bolts.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).
- Reconnect the negative battery terminal.
- Test brake functionality in a safe area before driving normally.
