Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, safety glasses, gloves.
Ensure the vehicle is parked on a level surface, engage the parking brake, and wear safety equipment.

2. Raise the Vehicle

Loosen the lug nuts slightly but do not remove them.
Using a jack, lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by loosening the caliper bolts with the appropriate socket.
Carefully slide the caliper off the rotor and suspend it using a bungee cord or similar tool to avoid stressing the brake line.
Inspect the brake pads for wear; replace if the thickness is below 3mm or if they show signs of uneven wear.
Sub-steps:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated correctly.

4. Inspect and Resurface or Replace Rotors

Check the brake rotors for grooves, rust, or warping.
If the rotors are salvageable, use a brake lathe to resurface them. If excessively worn, replace them.
Sub-steps:
- If replacing, remove the rotor by unbolting it from the hub.
- Install the new rotor and torque bolts to manufacturer specifications.

5. Reassemble Brake Components

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

6. Lower the Vehicle and Test

Remove the jack stands and lower the vehicle.
Torque the lug nuts to the specified value.
Test the brakes by applying pressure to ensure proper function and check for any remaining noises.
