So I'm new to the site, more of a guest really as I don't own a Ford (mopar guy actually, please don't shun me as I'm here trying to help a friend with his car). So I found a Co worker of mine brake spindle, calipers, and rotors from a 75-79 Granada while searching for disc brakes for my valiant. With a little research I fig they would be great on dans 69 and for $100 a steal. We replaced every thing and cleaned the spindles. We used 73 mustang outer tie rods. Since the Granada was long gone I couldn't get the proportioning valve and mc. We used a new mc from a 73 maverick for manual disc brakes and used the rod from the mustang mc. The new maverick rod was 1" longer. I was reading any Ford proportioning valve from a rear wheel drive disc front drum rear car should work. We used one from a early fox body mustang and then bleed the system real well. Now his peddle is rather soft not spongy like air in the system but soft like power brakes. But the thing I really don't like or get is he can't get his brakes to lock up at all. He said the brakes are a vast improvement but I'm not satisfied with them yet and don't want to see him or his classic car in an accident. Now I'm thinking its something with the fox body proportioning valve but before I start throwing any part or cash at this I was hoping for a little insight. Thank you.

 

Nevermind

 

As far as Im concerned, if he cant lock up the brakes but its an improvement in braking then there shouldnt be anything to complain about. It is probably his prop valve working with different size brakes then it was meant too. What size are the rotor/calipers?
