I am restoring a 54 GMC 1/2-ton Longbed PU and I am planning on installing power brakes with dual master cylinder. My truck currently has 4 wheel drum brakes and if I buy a power brake kit to work with my current setup, can I later upgrade my brake system to front disc brakes and still be able to use the same power brake system? I am asking since I see power brake systems for drum/drum, disc/drum, and disc/disc setups.
