Gonna put front and rear manual discs on my 70 Stang. Putting granada discs on the front and probably will put GM metric calipers on the back. Two questions. First what master cylinder will work with this application? Will a master for a 4 disc equipped versailles work? Also, will the stock granada prop valve work or do I need to add an aftermarket dial type prop valve? Further,with the aftermarket dial type, can you do away with the factory block and add a tee for the fronts, and add the dial type prop for the rears and dial in the amount of braking desired? Trying to get all of this straight in my head.Thanks for the help, Von

I'm installing my rear discs tomorrow on my 67 and been told the 70 Mustang disc/drum master will "hydro-dynamically" power my dual discs. I will put a slit between the bowls to allow fluid drops as disc pads wear. If this turns out not to work, I've been told the 87 LM Mark VII has a proper disc/disc master. Stay tuned.------------------

The Versailles MC will work, but you may need to exert a tad more pedal pressure without the booster it was designed for. You really need a MC with a slightly smaller bore if you're going manual. This will give you more pressure for the same pedal input. Of course the smaller bore will require a longer stroke in order to move the required amount of fluid.I would think the Mark VII MC would be a good possibility as well, but then again it was also spec'd for a power setup. I'd like to see the bore and stroke for both of these MC's. I'm running 4 wheel power disc and am using a '96 Windstar MC (Yes, a Windstar). It has the exact bore and stroke dimemsions I needed AND had it's ports on the left side (opposite motor) which was a requirement for me. You can see pics of it at my web site, www.472ci-67mustang.com . I'd stay away from any MC built for drum brakes in the rear. They won't move enough fluid for disc calipers, especially when the pads wear and the caliper piston has moved towards the rotor creating larger volume to be filled with fluid. The Granada prop valve should do just fine as Phil said. I have an aluminum Versailles MC polished to a show shine if your interested in it. Brian

A late 80's Lincoln master cylinder will work and as a plus it is aluminum, saving you 10 or so pounds in the process. ------------------
