Ok doing a power brake upgrade on my 57 Chevy. My master cylinder has a 2 inch stroke and my new booster only has 1.25 inch stroke. Is my booster jacked up internally? I know there is an adjustment at the end of the rod, but the full actuation of the booster is only 1 1/4 inches so regardless I wont ever get the full stroke of my master cylinder. It's a new 8 inch dual diaphram booster and a new corvette style master cylinder. Thanks in advance.
