granada disc brake question(help)

[pazcarguy]

Just purchased a granada disc brake setup for my 66 coupe from individual who has decided to take another route. Kit had in it rotors/calipers/spindles/pads and bearings. Laurel mountain mustang recommended a 67 master cylinder so I purchased this from them for 39$ new. Problem is that I have no granada proportioning valve and can't seem to locate one. After doing research, I found that I can tee front brake line just after master cylinder and put a manual (Summit) proportioning valve for rear brakes. Anyone do this and if so, pros/cons? Keep in mind that i cant locate the stock proportioning valve new, it is discontinued. Brian

I think your going to find that this is a fairly common set up. I have the Summit Adj Prop Valve in my 1966 Mustang daily driver/autocross car and have had no problems with it.

Good Luck

The manual proportioning valve is the way to go. It's by far superior to using the Granada one. I have the Granada one, and my rears lock first in a panic stop on my '70. Those are the pros, I am not aware of any cons.

One other thing, after a year of running mine, I finally realized that my master cylinder is missing the residual pressure valve for the rear drums. This makes my pedal soft on the first try. Make sure your MC has the residual pressure valve, or buy one for the rear drums.
