one question about brake lines when upgradeing to a duel master cylinder i have not been able to find. replacing the lines , is it best to stay with the same size? any advantage to going all 1/4. this is a 54 3100. probably going to stay with drums for now untill i get it on the road and driving more. i did rebuild a ft wheel cylinder and could not believe the crude built up in the cylinder and hose. the truck has set for 8 years. ccb
