Brake pressure regulator Options

[watsonrx13]

Eric's ad selling the 912 rear calipers started a discussion about the brake pressure regulator. I'd like to continue that discussion. Eric mentions that he wouldn't replace the regulator with a 'T' fitting. What I would like to know is how could you test the regulator off of the car? At $300 - $400 a piece from the dealer I would like to test mine before I purchase a new one.

Also, Eric mentioned that the front calipers shouldn't be used on the rear, even with the regulator. Is there any problem installing a set of rebuilt rears on and not installing the parking brake cables?

Any thoughts and suggestions are welcomed. BTW, I'd like to keep this discussion only for the 4-lug wheels.

Also, what are the thoughts about replacing the master cylinder with the larger one how does that effect the brake biasing?

If you're a racer looking for every last millisecond, you want all four brakes working as efficiently as possible. So using an adjustable proportioning valve will allow fine control over how much rear brake you're utilizing.

If you're a daily driver, you simple want the safety and the stock valve is fine for that.

What happens, often times, is that people apply race tech logic to daily driver cars and they're not always directly comparable. Some race tech is not a good choice for a street car where you really don't need it.
