Default Parking Brake Dash Light Flashes On & Off

I have a 2005, 4.6 F150. A month or so ago the parking brake light on the dash came on while I was driving, then went off. Didn't think much of, did it a couple weeks later. Now it seems to do it fairly often. There is no patern to is coming on, it'll even do it stopped at a stop sign & when I start it up. Rotors & pads are new & fluid level is good. The parking breake is not on. Anyone ever have this happen before, or have any idea what it is? Thanks.

Thanks, It seems it comes on & stays on when the truck is cold, but once I have driven for about 10 -15 mins it goes off for good, only when its cold. This isn't always the case, but the majority of time it seems like it is. Is there a sensor that could be going?

Well problem went away for a week, about 11 hours and 500 miles of driving, but all of a sudden it came back. I replaced the switch, but that didn't seem to be the problem. There is plenty of fluid in it. Is there a float or sensor in the master cylider that might be stuck or bad? Anyone ever have somthing like this happen before?

Thanks.
