To inspect hydraulic breaking system: pop the hood, know where break fluid reservoir is located, make sure the reservoir is greater than a quarter . Check for leaks at the engine and the ground. With the vehicle off, pump the brake 3 to 4 times until the brakes are hard; hold your foot on the brake and start the car which should release the pressure and drop the brake. Once the car is on, state that the brake system warning light is not on. Minor defect is if brake fluid below minimum level and major is if brake fluid is leaking or brake test fails.
