master cylinder

I have a 92 thor pinnacle with a 454 tbi engine.I am not sure if it has auto park brake.I do know that it has a brake light and a light for when the emergency brake is on that you push with your foot.I thought maybe it was the pedel next to the left side steering in the floor but when push it down and released it another light came on and nothing changed with the original brake light.It stayed on.So not sure about auto park on this vehicle.
