The original poster called them Pressure regulators so I just copied it into it. BTW...when I said on a computer controlled Brake system I meant anything that is electronic that is connected to the brake system to "contol" a certain function. I'm still stuck on working on ABS systems and more modern cars with all the fancy wiring going into the brake system. I keep forgetting the "mecahnical" ones like the Delorean as opposed to the "electrical" ones. I guess I'm just a youngen. :P Steve --- In dmcnews@xxxx, Josh Keady <joshkeady@xxxx> wrote: > I think you're thinking of a proportioning valve, and they're used on many > more cars than just the "computer controlled" other wise, you'd be getting > the rear wheels locking up all of the time.
