    Brake Distrution Block Swap

    I have a 1967 with a 289/Auto/4 wheel drum brakes.  I was hoping the group could tell me if my plans for the brake system are feasible.
     
    The distribution block I have is stuck and I’ve tried opening up one of the bleeders and stabbing the brakes etc. and nothing seems to unstick it.  At some point I want to upgrade the system to disc brakes, but I can’t afford to do that right now.
     
    This is the plan I’ve come up with.  Replace the distribution block with a block for disc brakes.  The only difference I know of is that the port for the left front brake (coming out of the port facing the front of the car) is 3/8 to 7/16 on the drum brake distribution valve and ½ to 7/16 on the disc brake distribution valve.  Are there other differences that would I don’t know about that could give me problems?
     
    I hope that when I am able to do the disc brake conversion, I will be able to connect straight to the distribution block and not have to use the adjustable valve that some kits come with.  Seems too easy, so what am I missing? 
     
    Thanks in advance, Brian.

    Re: Brake Distrution Block Swap

    The disc brake valve contains a proportioning valve that limits pressure to the rear brakes. The drum brake valve is a simple differential pressure valve with no proportioning valve function.
    The disc brake valve is probably not a good idea on a drum brake car.
    I do carry the disc brake combination valves and I provide the proper tube nuts to fit the 7/16" threads on the rear line connections.

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.
