PDWA or not?

[Cinbearcat83]

I am making progress on the braking system of my +2 (US - Federal). I am not reinstalling the servos. As I fabricate new brake lines, I am interested in hearing opinions on whether to reinstall the PDWA. I have seen elsewhere on the forum, that others have deleted the PDWA. I appreciate your thoughts. - Kevin

For the uninitiated, what is PDWA?

Knowing what it is might result in some replies.

There is also a thing called a PDWA (pressure differential warning activator) which is located between the pistons on many tandem cylinders, its purpose is to light up the brake warning light if there is a failure in one circuit..
