    Hi,

    I think my 1971 LeBaron brake booster failed two weeks ago. Brake pedal went really hard to push and vacuum is leaking when pedal is pressed. Leaking voice can be heard clearly. This makes also engine running bad when idling, if brake pedal is pressed, but thats not really problem for me. Vacuum powered parking brake automatic release mechanism works fine.

    I'm interested to hear if someone has bought and installed "Pirate Jack" (china repro) brake booster.

    Later I might also send my original brake booster unit for rebuid. But now I want to enjoy short summer and I need a booster that Works.

    We have mandatory safety inspections every year at Finland. My "Imppu's" inspection is between August 8th and September 2nd. I need working brake booster at least then or I can't drive Imppu before fixing it.

    I think that my brake booster is Bendix dual diaphragm booster. How can I be sure?

    1.) The booster you cited will not fit a C-Body
    2.) You do have a Bendix Dual Diaphragm Booster
    3.) Getting it rebuilt is your best option, as far as I know the ChiComs do not make a replacement booster that is any where near correct for a C-Body.

    www.boosterdeweyexchange.com does an excellent job of rebuilding boosters to OEM standards and will usually get in done in about two weeks.
