Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues (if applicable).

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if they are below 3mm, replace them.
Remove the caliper bolts with a socket wrench.
Slide the caliper off the rotor and support it without straining the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly in the bracket.

4. Inspect and Resurface/Replace Rotors

Check the rotors for signs of scoring or warping.
If damaged, remove the rotors by loosening the retaining screws or bolts.
Resurface the rotors if they are within specs or replace them if they are excessively worn.

5. Reassemble Brake Components

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern to the specified torque.

6. Test Brake System

Reconnect the battery (if disconnected).
Pump the brake pedal to ensure proper pad and rotor contact.
Perform a test drive to check for any remaining noise or issues.
