m932 parking brake buzzer keeps buzzing after parking brake is released

My m932 A1 parking brake buzzer keeps buzzing after being released. The air pressure is up to the level it should be and the warning light blinks.

Mine was doing the same thing. the valve with the roller tip on it mounted to the parking brake lever seemed to be at least part of the problem , i would flip it a bunch of times with my finger and the buzzer would finally stop. Im not sure if there is another sensor sticking further down the air circuit or if its just the valve. Anyway way it finally stopped sticking.

The failsafe warning box by the drivers left foot is problematic. I had to replace mine to get the buzzer to stop. That was after checking everything else out. White owl has the part.

Do a search. I did a post on this.

Yep been doing that. I can also tell this truck has been sitting for awhile. The accelerator kept sticking and we freed it up with some PB Blaster.

If you still have problems PM me your number and I'll call you. Took me a few days to figure mine out. Had multiple issues.

Thanks will mess with it tomorrow. I can't figure it out I will PM you.

Mine had a loose wire coming from the switch . The wire was under the truck.
