Rear disc brake swap 72 K20
Looking for some help. Swapped a 14 bolt from a 2002 Silverado into my 72 K20.Issue I am having is not getting enough fluid volume to operate the factory 02 dual piston calipers. Currently have the stock 72 master,booster and a disc/ disc prop valve . The 72 booster won't accept a larger bore master cylinder,any thoughts?
