Thanks ECIGuy. After talking to you, I have done a little research and found that you were correct (didn't doubt it) and that the booster and m/c I have mounted on the firewall is for a disc/drum set up. I'm trying to find the firewall mounted drum/drum master cylinder that I can attach the booster to that will fit my 49 dodge. Any ideas would be great. What years of the chevy's ran drum/drum master cylinders that also can use a booster. THanks guys.
I have a set up from a 1985 montecarlo on the firewall now. I was told by a local rodder that I could buy some 10 lb residual proportioning valves and put them inline after the m/c and that would drastically improve the stopping. any thoughts
if you want it to be easy, a GM master cylinder from pretty much any car from the 50's or so will take a VH44 or VH40 remote booster. Most people seem happy enough with that set up but i dont like it myself unless i really need the space. jump on ebay and check out those firewall booster kits for Belairs/Impalas. they would allbe disc/drum i would say (i hope as i am about to fit one without a valve!) but many of them come with a seperate proportioning valve that bolts to the assembly and grabs the fluid on its way out. with one of these you can set up what kind of brake response you want with fine adjustment.
dunno that this set up would work drum/drum though. ask the sellers if you can find one that sells them seperately to the kits. with a good one it should but.. you know... ebay... if its better brakes you are after i would actually look at converting the front to disc. it will drastically help braking distance and wheel lock. you just need to figure out what stubs will fit in your set up and go down to the junk yard and take a whole set up from whatever will work.
There's no reason you can't use a disc/drum master with drum/drums. Why would you think otherwise? You will need one or two 10 lb residuals, if one is not behind the rear drum brake tube seat in the disc/drum master.
