hello all, having issues with my newport. it takes alot to stop the car. not sure whats going on. new master and booster, bled all lines, checked all brakes shoes and drums all look good. the only thing is low manifold vacuum, only showing 10 at idle. it does have an agressive cam, i know the power brakes need more. the car feels like manual drum brakes with no power assist. been searching and cant find anything. running out of ideas. car is a 68 with a built 383 and 4 wheel power drum...
68 newport not stopping as it should?
