Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Brake Components

A. Remove Wheel

Use a socket set to loosen the lug nuts while the vehicle is on the ground.
Lift the vehicle using a floor jack and secure it on jack stands.
Fully remove the lug nuts and take off the wheel.

B. Inspect Brake Rotors and Pads

Visually inspect the brake rotors for grooves, cracks, or warping. Use a caliper gauge if necessary.
Check the brake pads for uneven wear or damage.
If warped or worn, proceed to replace the rotors and pads.

3. Replace Brake Rotors

Remove the caliper by unscrewing the caliper mounting bolts with a socket set.
Hang the caliper securely using a bungee cord or caliper hanger (do not let it hang by the brake line).
Remove the rotor by unscrewing any retaining screws if applicable.
Install the new rotor, ensuring it is seated properly.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Apply brake grease to the backing of the new pads (avoid contact with the friction material).
Install the new pads into the caliper bracket.

5. Reassemble and Test

Reattach the caliper over the new pads and rotor, tightening the mounting bolts to the manufacturer's specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value in a crisscross pattern.
