Park Brake light won't go out

Hi all,
Took off on our FIRST RV excursion this weekend. Kind of a shake-down cruise
First issue: Air brakes:-the Park Brake warning lamp stays on when I release the parking brake.
This is a new thing. Didn't do it a couple weeks ago when we brought the coach home.
With park Brake on, the coach doesn't move, park Brake off, moves normally. So I'm pretty confidant that the park Brake is working normally.
Any ideas where to start looking for whatever is causing the lamp to stay on?
I replaced air Filter/dryer today, but I can't imagine how that could cause this issue.

Behind the park brake button is a air valve. It may have the switch screwed right into it.

See if you can pull the panel that holds the button. Look behind it for the switch. Any truck shop should have it.

It may look like this,

One thing I found that works is always release park brake when air tanks are at FULL pressure (about 120#).. Mine light will stay on if I don't wait till full pressure. Try that.... If not then replace the pressure sensor under the park brake switch in the drivers side arm rest...

Good Luck
