Hey guys, so here's my situation. On my '63 Dodge D100 I have replaced the following... Master cyl. with a dual chamber unit with correct bore, front hard lines, front hoses, front drums and shoes. I didn't do the rear drums or shoes because it's really hard to find tapered axle drums. The rear drums are done for... but the shoes looked ok. I bled and bled the brakes, yes I bench bled the master as well. I just can't seem to get a good pedal, I know the rear hose could be suspect and I'm gonna swap it tomorrow. I'm starting to think maybe a bad master cylinder? Also, my friend who works in a shop says my pushrod is 3/8 of an inch too short. It's the one I pulled from the old single pot master. Would that really cause all this trouble? It doesn't seem too short to me, but what do I know? That's why I'm asking you guys. This isn't the first time I've done this kind of thing... I rueplaced everything on my girlfriends OT truck (73) and it was all bled and good to go the same day. I also helped convert a '65 Plymouth to dual circuit and it took time to find out it had a bad master cyl (remanufactured). Mine is also reman. but I don't want to just assume that's the culprit. Sorry for the long post just want to lay it all out there. Thanks in advance fellas.
