mine is the older bendix. After I get the master cylinder repair kit from Jim Carter, and IF that works, and I still have problems, I'm going to do something about the hydrovac. In one of the online catalogs I saw someone had a rebuilt one for almost $600.00. That's a big plate of not gonna happen. If I can't repair it, I going to disconnect it, and forget about it. I don't really need it. I'm not likely to put 5 tons on the old truck and go anywhere. Plain old brakes should stop anything I would put on it. Do you know anything about repairing a unit like I have? Is it a big deal, and are parts available. Again, thanks for your help. I do appreciate all the effort you are making to help. Allen
