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.
The power booster check valve would be located where the vacuum hose is connected to the booster. The vacuum hose is connected to the valve and the valve is inserted into the booster. They are usually made of plastic.
My 86 has a vac diagram just above the rad
the diagram you are looking for is on the fan guard connected to your radiator
From the booster, to a vacuum source on the engine.
Hold Vacuum in the booster during low vacuum conditions. (Basically if you lose your vacuum booster while you drive the one way check valve allows you to have two full stops left of vacuum assist.) they are federally mandated.
Phew and Wow, there are many vacuum diagrams-heater/air control,brake booster,rear driveline etc.Can you be more specific and include engine size.
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.
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 only thing to do is replace your cam with a lower duration cam or you can try adding a brake booster resevior to store vacuum for the power booster. == With such low vacuum, you might want to add an electric vacuum booster pump to augment the vacuum booster resevoir.
Having a diagram of the hoses in a car will help ensure that everything is properly changed and connected. The vacuum hose diagram for a 1986 Chevy Pick up v6 can be found in its maintenance manual.
Yes, the power brakes should work properly provided that the booster, check valve and hoses are in good condition and is getting the correct vacuum flow from the engine. The vacuum canister is a vacuum reservoir for the HVAC (Heating, Ventilation, Air Conditioning) controls.
