The newer drum brakes are self energizing. 48 and earlier fords were not. that's why in the old days we all wanted lincoln or '50's ford pickup setups..the force you apply at the pedal IS NOT a straight line graph of the stopping power at the wheels... Disc brakes come closer to a straight line. TRying to match that setup with self energizing fronts and disc rear. . to get good operation at slow. hard and panic stops would be very very dififcult. Front brakes do most of the stopping so front disc's-- rear drums is easier to get a compromise braking system . 4 wheel disc brakes with 2 master cylinders and an adjustment balancing bar like the original 427 cobra makes it easy to adjust front to rear balance... Several companies now make that style setup, Check your speedway catalog. for the wilwood setup. .. retired Ford engineer.
