Brake vacuum check valve

It seems to me that my car has, or had, a vacuum valve in the vacuum hose on the intake manifold.

A fitting screwed into the manifold and a hose went from there to the booster.

Hi Dick,
Thanks for that. It makes sense as the car I am working on has webers and no valve that I could find. I will look on the original manifold that I have to see if it is still there. Knowing that they originally came with a fitting makes sense as these cars would have little assisted braking whenever the throttle was wide open.
Thanks Mike

After a total restoration of my brakes and booster I did not notice any check valve in the brake vacuum line. This would account for a dramatic loss of brakes when the car stalls and braking is required. The parts manual does not show one. Is there an in line valve or should the banjo fitting that connects the vacuum line to the booster be one way? Thanks Mike

where can I buy onre of those valve's?
I need one for my Longchamp.

Mystery solved. The Pantera has a check valve in the banjo fitting that goes directly onto the booster. I took off the hose from the hard line under the front area and the vacuum side I could hear a "valve type" noise and when blowing the valve closes and holds pressure. As to where to find one for your Lonchamp I would try the usual US vendors as it is probably the same if it has a Benaldi Booster.

Thanks 69goose,
have any of you a valve for sale from a Pantera?
Banjo type also on my Longchamp

Simon, I just received 2 brand new vacuum check valves from Wilkinson Pantera at a very reasonable $24US each. I would assume the Longchamp ones are the same if it has a Bonaldi booster.

69goose ,thanks for the info I go look if it's the same.

Hi, I just order a vacuum check valve and banjo bolt by Wilkinson.
thanks for the help

Since the Benaldi is basically a Bendix copy, I would see if you can use a Mustang/Ford generic valve and rubber grommet.

Put the grommet in place, lube the valve barbs a tad, and push it in place!

If you happen to have an old Ford booster lying around........or in the driveway!
