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..

This will have been originally fitted because of it being a regulated design standard. Technically you’ll therefore be making the car illegal by deleting it. Whether any inspector notices or has any idea of what the original specification was however is entirely another question

In my state of Michigan (USA), there are no inspections on vehicles, so I have the freedom to delete it. I was curious if others thought it was worth reinstalling it. The previous owner removed the unit and cut the leads to the electrical sensor when he was restoring it. The unit was in a box of parts when I received the car. - thanks, Kevin

Whether you have inspectors or not isn’t related to whether the vehicle is legal or not. That part was a regulated design feature required to be fitted for the car to be allowed to be sold and distributed when new. Deleting it now technically makes the car illegal. Since it was originally regulated for safety reasons it is not something I’d be deleting personally speaking. Whilst deleting it may not have a direct affect on you because you know of the modification it may effect future owners further down the line.
