1972 Buick skylark car has Four wheel power drum brakes has a power booster has a dual reservoir master cylinder . My question is will I be able to use the booster and the master cylinder that is on car And what about a proportioning valve ?? I have everything I need to do from the spindles out
You will be able to use your existing booster but will need a disc/drum master cyl and prop valve. I have had good luck with Pirate Jack or Inline Tube.
