All of the trifive vendors sell a dual reservoir MC. Most of them will require a proportioning valve. As for less-pain, I went with the CPP unit that has a built in proportioning valve. Yea, it costs a bit more, but it's simple... and I like that. Here is a link to what I'm talking about..http://www.classicperform.com/NewProducts/MCPV-1/MCPV-1.htmI'm looking to see if anybody knows of a "painless" way to convert a '55 Chevy with a single-reservoir Master cylinder over to one with a dual-reservoir.
If you are running 4 wheel drum brakes you don't need a proportioning valve. All you really need is a dual master that many vendors sell and an additional brake line running to the rear brakes from one of the master cylinders. There are lots of posts here showing how
You can expect it to hurt a little when you unbolt the old MC from the four studs and notice that there are only two bolt holes in the new MC, and even worse that the two studs you can use might be too short to thread the nut on all the way. It will probably be OK (depending on the new MC), but for a little more pain you can worry the short studs out and replace them with longer ones.I'm looking to see if anybody knows of a "painless" way to convert a '55 Chevy with a single-reservoir Master cylinder over to one with a dual-reservoir.
No. In fact, you may not need a prop valve with front discs/rear drums. All the valve does is limit pressure to the rear brakes. It's required when, and ONLY when, a car's rear brakes lock up well before the fronts. Even then, an adjustable valve is the best way to go.Would it make sense to get one with a proportioning valve in anticipation of front discs in the future?
