Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the key is removed from the ignition.

2. Remove Wheel

Use a socket set to loosen and remove the lug nuts from the wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect Brake Components

Check the brake pads for thickness; replace if they are below 3mm.
Inspect the brake rotors for any grooves or uneven wear; consider resurfacing or replacing if necessary.
Ensure that the brake calipers are functioning properly and not sticking.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket set and slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly.
Reattach the caliper and torque the bolts to manufacturer specifications (typically 25-35 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and tighten the lug nuts in a crisscross pattern to the manufacturer’s torque specifications (typically 80-100 ft-lbs).
Lower the vehicle and remove jack stands.
Pump the brake pedal several times to ensure the brake pads seat properly.
