Next week I plan to update my daily driver from a single to dual master cylinder. I have seen alot of info on this but am looking for a couple of specifics. I have drums on all four corners. I am looking to use a 67 dual MC (manual drum)and I believe I just need a "t" for the front brakes, plumb into the MC and then run the back line straight into second reservior of the MC. Will this work? I know I can't use my distro block currently in the car. Do I need a propotioning valve/distro block for this to work properly? Am I going to have lock-up, or better yet, does the 67 dual MC manual drum brake system use a distro block or proportioning valve in it's application? Any help in this matter would be greatly appreciated.
