Just for conversation, I used 1974 disc/drum setup on my Mav, and I cannot get the rears to lock at all. The brakes stop the car fine, just can't get the rears or fronts to lock up. I used the '74 prop valve on the Comet. I am thinking of putting in an adjustable prop valve, maybe I can improve the braking. Any suggestions? Earl
Jim, you will have this now and then. The main point is that with home engineered changes, the dynamics need to be known and not just put parts togather. There are many different control valve designs depending on the combinations. The design is bassed on the original weight, tires, brake pad/shoe designs etc. Change just one thing and the original design is out the window. The main points here IMO are that the reservior has enough capacity, the pressure distribution be set up as correct as possible for max brakeing and the workmanship be high. We are all responsible for what happens out on the road if there is an accident and a wise lawyer finds out the car has been modified. There is no hiding behind the phrase 'the brakes failed'. Good luck and keep it all in perspective.
since I no longer have the small car with the e-brake that you can get you sideways through a turn I switched to a distribution block, and with my discs I can slide through any turn I want!
'74 used the same distribution block on their disc/drum setups as '71-'73 drum/drum set-ups. Ford went to a prop-valve in '75...
So,this implies that if I just use a disc/drum master cylinder along with the Granada discs and 10inch rear drum hardware that I have duplicated a 1974 factory setup?Interesting.
