Brake Booster Check Valve
« on: August 2, 2009, 11:26:21 PM »
I found the brake booster check valve has a crack.  Where can I locate one, the local auto parts places don't even show them available??

    The dealer should have them.  There are a few different sizes/types depending on year and options.

    I think blueduster used to be a dodge dealer parts counter guy in the vegas area. He may be able to point you towards a particular dealer.
    Avoid replacing any part that you have not proven to be faulty through extensive testing.

    try Raybestos PN CV89000 for a single line, CV89004 if you have 2 -

    either one should work (just a matter of routing "extra" vacuum lines back to the intake), and they should be $7-10 each

    Be aware that there are different sizes of the part that fits into the booster.  For example, the 1990 Parts Manual lists 3/4" and 1".  Possibly for the D44 and D60 booster.

    The one on mine has 3 lines, one in the front is capped off.  One goes to the manifold and the broken one runs to a box, which I think is part of the cruise control.

    The only issue, is that mine has 3 nipples.  1 on each side and 1 in the fron that is capped off.  Will that make a difference?

    No, run the main feed from the intake manifld into the brake booster...

    Run the other line back to the vacuum tree on the intake
