Just wondering ... why the Ford M/C (and proportioning valve) call for separate lines to the front brakes, but not the rear in a disc/disc setup? Is this a "safety" feature? What would happen if I plugged one of the two front outlets and only ran a single line?
On the early dual circuit systems ( post 67) Ford uses the pressure differential valve (often mistakenly called the "Prop" valve) to split the front brakes into right and left thereby eliminating an additional splitter. A single line goes to the rear and is split on the rear axle.
Thanks for the information. don't know year/model on the M/C other than it's a Ford, and came from a disc/disc setup. Definitely not a Mustang fruit jar -- sorry if I didn't make that clear enough. Still unsure as to what the effect of plugging one outlet would be and running only a single line to the front -- with a T-connector providing juice to the off side. But I appreciate the help.
All of the dual master cyl. changes I've done they have the front split and a single line to the rear. Must be a good reason cause they could save tubing and stuff. I'd just do it the way they say and go on. $0.02
I have done many late model Power Brake to older vehicles and found by staying with the original pluming it works every time without problems.When junk yard shopping I get the complete under hood system then adapt the vehicle to the system. It has always worked for me.
