Want this question answered?
the line is connected to the carburettor if you have one or to the intake manifold after the throttle valve. The purpose is to connect intake vacuum to the booster.
you need manifold vacuum for the brake booster.. (intake manifold)
No, the brake booster operates off of vacuum not electricity. If the booster isn't working then check the vacuum line going from the intake manifold to the booster. If the line is ok and not leaking then you need to replace the booster.
the brake vacuum booster connects to the intake manifold all by itself and the PCV valve hose should hook directly to your carburetor.
The Vacuum line usually connects to the brake booster , or atleast it does in my Ford explorer
Any place there is a vacuum hose, under the hood and under the dash. Also the Power Brake Booster hose. The Booster diaphragm may also be busted. An Intake Manifold Gasket or the Intake Plenum gasket are sources of a vacuum leak.
the vacuum comes from the intake manifold
The Vacuum line for an automatic transmission runs from the modulator valve on the rear of the transmission to a vacuum port on the intake of the engine. Any available port will do as long as it is on the intake, not the carburetor if so equipped.
Located on the head of the engine, at the end of the intake or exhaust cam.
It is almost certainly a problem with the vacuum booster. Is the line connected and not kinked. Pull the check valve out of the booster and see if there is vacuum in the line. Booster do go bad and may have nothing to do with the intake. Higher speeds will produce more vacuum.
hook a vacuum gauge up to any of the rubber hoses that are coming out of the intake manifold, such as the brake booster....
engine vacuum or direct into the intake.
