Solution

1. Preparation

Gather necessary tools and parts.
Secure the vehicle on a level surface and engage the parking brake.
Use jack stands to support the vehicle safely after lifting it with a jack.

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts slightly.
Lift the vehicle with a hydraulic jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
If necessary, compress the caliper piston using a caliper tool to make room for new pads.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly in the bracket.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotor surface for grooves or excessive wear; if damaged, remove the rotor by unscrewing the retaining screws (if equipped).
Install new rotors, making sure to clean them with brake cleaner to remove any protective oil.
Reinstall the caliper over the new pads.

5. Reassemble and Test

Reinstall the caliper bolts and torque them to the manufacturer's specifications (typically around 20-30 ft-lbs).
Reattach the wheel and tighten the lug nuts in a crisscross pattern to ensure even tightness.
Lower the vehicle and perform a final check of all components.
