nobody ever had this problem?

Could be a bad ground, check the cab ground, typically located in the driver's side kick panel, screw into the sheet metal with a "bunch 'o wires" hooked to it. Might also be a bad brake light bulb, perhaps someone put in a single filament bulb in place of a dual filament bulb. Remove the brake light bulbs and see if the problem mains or not.

I agree on checking the bulb, sometimes when a dual filament burns out only one filament burns out (i.e. brakes but not tails or vise versa.) When this happens the burnt out filament can fall on to the good filament and cause all kinds of interesting lighting (i.e. hitting the brakes and all lights in the car brighten up like a brake light) Confused the hell out of me the first time I saw it.

your brake light circuit and parking circuits are joined.

Do you have a towing lights connection 4 or 7 pin at the back end? That is where my problem started like this....
