Hissing from the brake pedals being push indicates that there is air in the brake system. It also indicates that the brake pads may be wore down and are not able to grab to stop the car.
To vacuum test a brake booster, first ensure the engine is off and the brake pedal is fully depressed to release any residual pressure. Next, disconnect the vacuum hose from the brake booster and attach a hand-held vacuum pump to the booster’s vacuum port.
