The anti-creep device (ACD) is in line with the brake line going to the rear brake cylinders, it has no bleed valve. So, when you bleed the rear brakes, you will automatically bleed the ACD.

The real trick is to get the whole anti-creep system in sync. There is a switch on the carb accelerator linkage which must be adjusted just right after any change is done to the idle, a solenoid valve on the tranny that may or may not be functional, the ACD itself which if broken cannot be fixed but only replace and good luck at finding one of those, and a fuse in the wiring system that at 50+ years is likely blown. When the system is working it is really awesome and fun to show off the "old" studebaker technology to friends....and to take pride that 50 years later a car manufacturer, Volkswagen, is using the same idea...finally! I just fixed the anitcreep on my new 55 sedan, it had a broken switch on the carb linkage. Sure is fun to have it working.

Check out the shop manual for all of the procedures, it outlines them well...look in the carb adjustment section and also in the tranny section.

PS -I tried to fix a ACD on my other 55' and found out that it can't be done. I had the unit mounted in a large bench vise secured to a very heavy work bench and then I put a 3 foot long plumbers wrench, which weighs 30 lbs, on it and gave it a good torquing. I didn't get very far, I nearly tipped over my work bench and only budged the ACD to unscrew by just a little bit. So I learned that the factory made them unserviceable.

Hope that helps,
