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.
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.
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.
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.
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.
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.

If you have power brakes it may be the vacuum booster. The booster may be going bad, the check valve in the vacuum line or a cracked vacuum line.
Sounds like it could be a problem with the vacuum booster or vacuum supply to the booster Check for a vacuum leak Make sure the check valve on the booster is working Check the vacuum canister
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.
Yes, it is typically in the fitting on the booster where the vacuum line is attached.

If you have a booster you need a vacuum line to perform effectively, disc or drum.

The vacuum pump is to provide vacuum to operate the power brake booster.
Which vacuum diagram The Underhood for the engine or the vacuum for the interior /AC system?
It's the "power" in your power breaks.
You are taking too much vacuum away from the vacuum booster in the brake system. Try to find a smaller vacuum hose somewhere else in the engine to use for the Hydro Booster. The boost line for the brakes comes from the primary vacuum port on the intake manifold. Use a secondary vacuum source. That vacuum for the brakes needs to be undisturbed for correct operation of the braking system and the ABS if so equipped.
You probably have air in the lines or the brake booster is losing vacuum. Have the brakes bleed and have someone put a vacuum gauge on the booster,
If you look at the vacuum diagram on the underside of the hood you will see that if a vacuum reservoir was used it would be located near to or off of the Power Brake booster vacuum supply line. I know this because I'm trying to find a vacuum reservoir myself for my 91 Dodge , B250,with 239cid. Why are you looking for one? Henrij.
It could be a leaking vacuum hose to the power brake booster or the membrane in the booster could have a hole. When the brakes are applied, the booster is opened to the engine vacuum via the hose. The vacuum leak would then increase, causing the engine to stall.
