Has anyone mounted a dual master cylinder on their big bolt chevy truck? This topic has come up different times but I'm hoping I can run into someone who has done it successfully. I'm using the original 216 engine with drum/drum brakes. All rebuilt wheel cylinders, a mid 70s chevy vaccum booster mounted under the cab, orginal vaccum line that went to the hydro-vac system I now have piped into the vaccum booster, new brake lines but just cant seem to get bled. The dual master cylinder I'm using is from a late 70s g30 or p30 chevy like a one ton box van with 1.25 bore size advertised as power drum....both resivore are pretty even one side might be just a touch bigger....any suggestion or thoughts to help me out, thanks!!
