this article says, it isn't doing that. it just helps prevent rear lockup's or over bias.
Too many people without a clue about how a disc/drum brake system works give poor advice.
The factory combination valve incorporates the functions in your link and more. Lack of a combo valve will not keep your discs from working. You could plumb the M/C direct to the front and rear brakes and they would work after a fashion. But they would not work properly do to the inherent differences in how drums and discs operate. The rears would tend to lock up first.
If you have a FSM from the drum/disc pre-ABS era there is a pretty good write up in there on how they work and why.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
