RE: brake question?
ok i will clarify even better:
2 brake lines will go to 4 wheels, each line will split and go to 2 wheels. but there are 2 types of designs:
diaginal split = 1 brake line will split to a front and back wheel. the other brake line will split and go to the other front and rear wheels.
front/rear = 1 brake line will split to both front wheels. the other brake line will split and go to both rear wheels.
make more sense?
keep in mind that this is seperate from the ABS brakes.

WOW
History (some of which I lived):
Pre-60's master cylinders the world over were primarily a single piston w/ a single line running out to a splitter running out to the 4 wheels. Since auto manufactures had just recently gone from cable to hydraulic operation the brake systems still lacked any redundency, if the master had an issue . . . no brakes anywhere (throw out the anchor).
Then someone got the bright idea to put two pistons and two independent lines out, and that to better balance the system if one of the master cylinder circuits failed, they made one line and master cylinder piston do FL and RR while the other did FR and RL wheels. This was the about same time that somebody learned that front disc brakes were better than four drums. Well the disc have more line pressure and heatso this split provided a higher level of saftey if a brake line blew out, but there was no F/R bias just a redundant set of brake lines.
Time passes and ABS comes along adding more complexity to the brake system. But the existing government mandated laws are still in place as a minimum requirement. I believe that our ABS manifold is capable of distributing any master cylinder pressure input to any of the four wheels, which exceeds the legal requirements. Notice that our master cylinders have two lines going to the ABS manifold.
A4speed relax . . . you got BETTER than diagional split.
Cincy . . . you got all the exploded parts diagrams? Me likey.
