Goofy Instrument Warning Lights

[Mike_EX]

On my 2000 Montana, I have recently been getting erroneous
Parking "Brake" and "Trac Off" Lights. They always seem to come on when I start the car, but go away after driving a while. The Parking Brake is, of course, really off, but when the "Trac Off" Light is on,
the Traction System is really off. Any ideas? Thanks.

I replaced the front disc pads. Lights have gone away. Now to figure out the rear wiper....
