Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery if necessary for safety.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection: Measure the thickness of the rotors. If they are below the manufacturer's minimum specification or warped, replace them.
Replacement:
1. Remove the caliper by unscrewing the caliper mounting bolts.
2. Suspend the caliper using a wire or bungee (do not let it hang by the brake line).
3. Remove the old rotor by unscrewing any retaining screws if applicable.
4. Install the new rotor, ensuring it is secure.
5. Reinstall the caliper, tightening bolts to manufacturer specifications.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points of the new pads.
Install new brake pads ensuring they are correctly oriented.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Reconnect the battery if it was disconnected.
