Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel that corresponds to the affected brake.
Jack the vehicle up securely and place jack stands underneath.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Check for warping using a dial indicator or visual inspection.
If warped, remove the brake caliper by unbolting it and sliding it off the rotor.
Use a brake rotor tool to remove the rotor if necessary.
Replace with a new rotor if warping exceeds manufacturer specifications.

B. Inspect Brake Pads

Check the thickness and condition of the brake pads.
If they are worn unevenly, replace the pads with new ones as necessary.

4. Reassemble Components

Install the new brake rotor (if applicable) and torque to manufacturer specifications (e.g., 80-100 ft-lbs).
Reinstall the brake caliper and torque bolts to the specified value.
Reinstall the wheel and hand-tighten the lug nuts.

5. Recheck and Lower Vehicle

Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer’s specification (typically 100-150 ft-lbs).
Test the brake pedal and ensure it feels firm before driving.
