Tilton Screw Type Brake Proportioning Valve - Bias Adjuster Race Car / Rally Car

Thinking of putting one in the front to rear brake lines and wondering do you have to have one for each circuit??

Or is there a better option??

Generally cars with bias valves like that don't have split front/back circuits. the back brakes are fed (often by a balance bar pedal box) by a single pipe that goes to a t-piece at the back axle. Hence only one outlet. This set up is normally found on track/race cars, they tend to be maintaned more thoroughly, and driven differently so the safety aspect of the split circuit isn't vital.

If you wanted to keep a split circuit, you'd need two of those....but that doesn't seem like a good idea to me. How would you make sure the braking force is even?

To use one of these you need to join the 2 rear inputs together, feed it though the bias valve and then split it again.

Why do you need one of these bud? are your back brakes locking up before the fronts or something???
