Thread: Proportioning Valve? Dual inlet/outlet vs Single inlet/outlet

Tweet

Thx Pat. This is interesting. I was looking at the second item you posted. Right now I have 4 drums with a single reservoir MC (non boosted). As you can imagine, for safety, I want to upgrade to a dual reservoir asap and figured while I was at it, get a boosted unit. So I picked up a MC conversion kit for my car that came with a dual diaphragm 7" booster, dual MC and all the necessary bracketry. The kit states it is ok for a drum/drum or a disc/drum set up. Due to funding, I'll stay with drum/drum for now but will be swapping out my front drums for discs asap. I am trying to make sure I have all the pieces in place now to avoid headaches with my future plans for this car.

I think I am on track, but welcome the advice.

I'm pretty sure my suburban had been converted to discs before I got it because it has a six lug rear and 5on5 front discs. I'm not sure if any of it was done properly, but it appears that it was run the way it is for long enough for leaking oil to form dirt crud everywhere. I've just about got the truck running, so I guess I'll try it out, CAREFULLY! I have several of those five port valves laying around and I'll re-plumb if needed

HemiTCoupe I don't know if you are still following this thread but if you are can you explain something to me? If you have a dual master cylinder why would you need a block to separate the front and back?
