The vacuum hose on the brake booster typically connects to the intake manifold of the engine. This connection allows the brake booster to utilize engine vacuum to assist in applying the brakes, making it easier to press the brake pedal. In some vehicles, the hose may also connect to a dedicated vacuum source or a vacuum pump, especially if the engine does not produce sufficient vacuum at idle. Ensure the hose is securely attached and free of leaks for optimal brake performance.
