D&D Disc Brake Setup for 67 Econoline

Post by Casimier on Tue Jan 10, 2017 1:50 pm



I just ordered the "D&D Disc Brake" setup for the 67 econoline.

I also contacted White Post Restorations in Virginia as to what has to be done to the 67 econoline 2 valve master cylinder for the disc brake system to work.

White Post rebuilt my master cylinder.

They said all that's needed is to remove the check valve that will be associated with the front disc brakes.

I was under the assumption that a 2 psi check valve was required for the disc brakes to work.

has anyone done the conversion?

Thanks Casimier

The general rule is, if the master is at or below the calipers a residual pressure valve is required. 2 psi for discs, 10 psi for drums. You may also find you need a proportional valve for the rear to brake at the the right ratio to the fronts. You need a 2# residual valve for the front discs and a 10# residual valve for the rear drums. I made my own system, but this is what I learned.

The '67 master had a 10# pressure valve for the front drums, which is why you have to change it out. If your master is above the disc brakes, then the you may not need the 2 pound valve, although they are cheap and fairly easy to include in-line before the splitter to the two front wheels.

anyone know where I can get a 2 psi check valve for my 67 master cylinder.
I'd rather replace the valve in the master cylinder than use aftermarket ADD ON

Basically you need a lighter spring under the residual valve.
