Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

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

3. Inspect Brake Components

Brake Pads: Check for thickness (minimum 3mm) and uneven wear; replace if necessary.
Brake Rotors: Use a micrometer to measure rotor thickness. If warped (more than 0.002 inches), resurface or replace.
Brake Calipers: Ensure calipers move freely; clean and lubricate sliding pins if necessary.

4. Replace or Repair Components

If brake pads are worn, replace them with high-quality aftermarket or OEM pads.
Resurface or replace rotors if they are warped.
If calipers are sticking, rebuild or replace them as necessary.

5. Reassemble and Test

Reinstall the wheel and tighten the lug nuts to the manufacturer’s specified torque (typically 80-100 ft-lbs).
Reconnect the battery.
Lower the vehicle and perform a test drive to ensure the issue is resolved.
