Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks
Raise the vehicle using a jack and secure it with jack stands. Ensure the vehicle is on a flat surface and use wheel chocks to prevent movement.

2. Remove Wheels

Loosen the lug nuts on the affected wheel(s) slightly before lifting the vehicle.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Components

Inspect Brake Pads: Check for uneven wear and measure the thickness. If they are below the manufacturer's recommended thickness, proceed to replace.
Inspect Brake Rotors: Check for any signs of warping or excessive wear. If damaged, replace or resurface the rotors.
Inspect Calipers: Ensure the calipers are functioning properly. If they are sticking, clean or replace them as necessary.

4. Brake Pad Replacement

Remove the caliper by unbolting it from the bracket. Use a torque wrench to ensure proper torque settings during reinstallation.
Take out the old brake pads and clean the caliper bracket and mounting surfaces.
Install new brake pads, ensuring they are seated properly.
Reinstall the caliper and torque the bolts to the manufacturer's specifications.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts in a star pattern to the manufacturer’s specifications.
Lower the vehicle and remove wheel chocks.
Pump the brake pedal a few times to seat the brake pads properly against the rotors.
