Questions & Answers
Q: How is this different from the standard Adjustable Proportioning Valve?

This rear-only valve is a simpler inline unit for the rear circuit alone. It does not include the pressure switch/brake-light connector that the standard combination-style valve has, and it isn't built to bolt to a stock distribution block bracket.

Q: Where do I install it?

It can be located anywhere in the rear brake line between the master cylinder (or distribution block) and the rear brake tee, giving you flexibility in mounting location.

Q: Does it include a brake light pressure switch?

No, unlike MustangSteve's standard Adjustable Proportioning Valve, this rear-only version doesn't include a pressure switch; it's focused solely on adjustable rear brake pressure control.
