Solution

1. Preparation

Gather all necessary tools and materials.
Ensure the vehicle is parked on a level surface and turn off the engine.
Put on safety gloves and goggles for protection.

2. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level against the minimum and maximum markings.
If low, top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).

3. Check for Leaks

Visually inspect the brake lines from the master cylinder to the brake calipers for any signs of fluid leakage.
Look around the brake calipers and wheel wells for wet spots or puddles of brake fluid.

4. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle's diagnostic port (usually located under the dashboard near the steering column).
Follow the scanner’s instructions to retrieve any brake-related error codes.
Document any error codes present and refer to the repair manual for further details.

5. Inspect Brake Components

Remove the wheel to gain access to the brake assembly.
Inspect the brake pads for thickness (replace if below 3mm).
Check the brake rotors for grooves or warping; measure thickness with a micrometer.
Ensure that calipers are moving freely and not seized.

6. Test Brake Pedal Feel

Start the engine and press the brake pedal firmly; it should feel firm and responsive.
With the engine off, pump the brake pedal several times to check for firmness. If it feels spongy, there may be air in the brake lines or a leak.
