06 model 2388, the parking brake light on "A" post and audible alarm came on today w/o engaging the parking brake switch. The brake is not engaged. Light on 100% of the time, audible alarm sounds only when moving. What is my problem?

you need to turn up your regulated pressure have a tech put a guage on the test port back above the batteries and turn up accordingly

Could also be the park brake pressure sensor down on top of the transmission.

We had a 2388 and that same thing happend to it, only the parking brake would engage. We had to step on both brake pedals and it would unlock the stuck brake. Hope this helps
