Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, torque wrench, brake cleaner, new brake pads, new rotors (if necessary), and a dial indicator.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts fully and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting the caliper bracket.
Slide the caliper off the rotor and secure it to avoid stress on the brake line.
Remove old brake pads and inspect for wear.
If worn, install new brake pads, ensuring they are correctly positioned.

4. Inspect and Replace Brake Rotors

Check rotors for warping using a dial indicator; if the runout exceeds manufacturer specifications, replace the rotors.
To replace, remove the old rotor by unbolting any retaining screws or clips.
Clean the hub surface with brake cleaner and install the new rotor.
Torque the rotor bolts to the specified manufacturer torque settings.

5. Reassemble and Test

Reattach the caliper over the new rotor and secure it with bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully torque the lug nuts in a star pattern.
Reconnect the battery.
