Rusty...AFAIK The front brakes should be the ones that receive pressure first.
That is, the first circuit to operate,bearing in mind that the fronts do most of the work.
I'm not sure what would happen the other way round but I imagine in an emergency stop you wouldn't want the rears coming on too hard first.
Especially on a truck which has a lighter back end anyway.
Therefor, I would reckon it is pretty important you plumb the master correctly....
Anyone else have the same opinion?
