Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, socket set, brake cleaner, and gloves.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Inspect Brake Components

Sub-steps:
- Remove the brake caliper by loosening the caliper bolts using a socket set.
- Carefully hang the caliper using a bungee cord to avoid straining the brake line.
- Remove the brake pads from the caliper bracket.
- Inspect the brake pads for thickness; replace if less than 3mm.
- Check the brake rotors for grooves or scoring; replace if necessary.

3. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
- If the brake pads are worn, install new pads by positioning them in the caliper bracket.
- If rotors are scored or warped, remove the old rotor by unscrewing the rotor retaining screws (if applicable) and sliding the rotor off the hub.
- Install the new rotor, ensuring it sits flat against the hub.
- Reinstall the caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer’s torque specifications.

4. Reassemble and Test

Sub-steps:
- Reinstall the wheel, tightening the lug nuts in a crisscross pattern to the specified torque.
- Lower the vehicle back to the ground.
- Pump the brake pedal a few times to seat the pads against the rotor before driving.
