Solution

1. Preparation

Tools Required: OBD-II scanner, torque wrench, socket set, brake fluid, safety glasses, gloves.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if performing extensive electrical diagnostics.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Follow the scanner's instructions to retrieve any error codes related to the brake system.
Take note of any codes for further diagnosis.

3. Inspect Brake Fluid and Components

Open the hood and locate the brake fluid reservoir.
Visually check the fluid level; add brake fluid if necessary.
Inspect brake lines and connections for signs of leakage or damage.
Check the condition of the brake pads and rotors by removing the wheel:
- Use the socket set to remove lug nuts and wheel.
- Inspect the thickness of the brake pads and look for any cracks or uneven wear.

4. Test Brake Functionality

With the vehicle stationary, press the brake pedal firmly.
Note if the pedal feels soft or spongy, indicating possible air in the brake lines or a failing master cylinder.
If the pedal is firm, proceed to test the brakes while driving to assess performance.
