Here's my problem: 1964 thru 1966 Imperials 4 wheel drum brakes with single outlet M/C going to a distribution fitting/T-fitting which then has an outlet for each front brake and a single outlet goin to rear brakes. Therefore a distribution block with 1 inlet(from M/C) and 3 outlets. I have found a late model car with front disc/rear drums. It has a dual outlet M/C with both pipes going to a proportioning(?) valve with 4 outlets(1 to each wheel) and an electrical connector presumably going to "brake warning light" in dash. My questions are: 1. With the new M/C installed in my 64/66 Imperial(it's a perfect fit) what problems do I run into if any, with the operation of the proportioning valve? 2. With only 1 brake line to the rear axle,what happens if I use only 1 rear outlet and plug the other 1 off? Would I also then have to plug 1 of the front outlets and plumb both front brakes on 1 outlet and the same for the rear brakes? If I did that (and it worked!) I would at least have 2 separate circuits for my brakes as opposed to the 1 only I have now for the whole car. Your thoughts on this are greatly appreciated.
