    How do you connect the lines from the distribution block on the frame thru the hold off valve to the master cylinder of a 1970 Buick GS 455 with power disc brakes. (Drum rear / Disc front)?

    Is this correct? Or would I be hooking them up backwards?

    #1 port from the rear connection on the distribution block go to the brake hold off valve and then the front port the master cylinder

    #2 port from the front connection on the distribution block go to the rear port of the master cylinder?

    Thanks,
    Nick

    If I read that right, it looks like I had it backwards. Thanks Larry!

    If I look at that right, the top or front connection of the block (my #2) looks like it goes to the hold off valve and then to the front of the master cylinder.

    Yes, the front line goes to the hold-off and then to the front brakes.
