Where does the vacuum hose for power brake booster go?
The vacuum hose for a power brake booster connects to the engine's intake manifold (or in some cases, a dedicated vacuum port on the engine) on one end and to a nipple or fitting on the brake booster on the other end. The exact location on the intake manifold can vary depending on the vehicle's make, model, and year. Consult your vehicle's repair manual or a reliable online resource (like a diagram specific to your vehicle's year/make/model) for the precise location.
