Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative terminal of the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect: Check brake pads for thickness. If they are worn down to 3mm or less, replacement is necessary.
Remove: Unbolt the caliper using a socket set and slide it off the rotor.
Replace: Remove the old brake pads and install new ones. Ensure they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Check: Measure rotor thickness with a micrometer. Replace if below the minimum specification or if damaged.
Remove: Unbolt the rotor from the hub assembly and slide it off.
Install: Place the new rotor onto the hub and secure it with bolts to the manufacturer's torque specifications.

5. Reassemble and Test

Reinstall the caliper over the new pads and secure it with bolts.
Put the wheel back on and tighten the lug nuts to the specified torque.
Reconnect the negative battery terminal.
