Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the negative battery terminal to prevent electrical short circuits.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove lug nuts using a socket set.
Take off the wheel and set it aside.

3. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads. If they are below 3mm, they need replacement.
Remove: Unbolt the caliper using a socket wrench and slide it off the rotor.
Replace: Slide out old brake pads from the caliper bracket. Install new brake pads, ensuring they are properly seated.

4. Inspect and Resurface/Replace Rotors

Inspect: Look for any grooves or uneven wear on the rotors.
Resurface: If minor scoring is present, use a brake lathe to resurface the rotors.
Replace: If the rotors are excessively worn or damaged, replace them with new units.

5. Reassemble Braking Components

Reattach: Slide the caliper back over the new pads and secure it with bolts.
Reinstall: Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower Vehicle: Carefully remove the jack stands and lower the vehicle back to the ground.

6. Final Checks

Tighten the lug nuts with a torque wrench to manufacturer specifications.
Reconnect the negative battery terminal.
