2012 RT Brake failure and parking brake lights stay on - any ideas?

[Mikey]

I checked the emergency brake pulley and micro switch. The pulley moves the parking brake cable approximately 1" and it turns the micro switch on and off. This does not confirm that the switch isn't malfunctioning. Is there an easy way to check the switch?

Another thought. There is a low pressure switch in the system that requires 500 psi and a minimum pedal travel if I understand it correctly. Could this be caused by air in the brake lines? If so, would it cause the Brake Failure and parking brake light to remain on?

Update:
I'll assume the switch is working. If I turn the ignition switch off with the parking brake disengaged, the warning beeper goes off.

Thanks,
Charlie

I read through this thread again, and you're saying you turn the key off with the ebrake off and the beeper did not go off? If that's what it's doing it should be beeping because you don't have the brake on!
