I've owned my truck for a couple months now. Ever since I owned it, the red BRAKE light has flashed in a timed manner repeatedly until I release the parking brake. One time sitting on a hill with the tailgate facing downhill, I parked in neutral, set the brake and the truck slowly started creeping backwards. Only happened once, and I park on that same hill all the time at my moms house. Since then I'm always very cautious to make sure my wheel is turned sharply incase the brake would let go. However, just recently, the blinking light continues to stay on and blink while driving. Now I've never worked on brakes ever, so I'm unfamiliar with them, but I've learned the blinking means it is parking brake related, not ABS or anything like that. The only thing I changed in that area was when I zip tied my Edge wires up around there... but I looked with the brake on and off, no wires are pinching, or blocking anything, and the pedal feels exactly the same as it did when I bought it. Feels very similar to my 2000 V10's brake, which had nothing wrong with it. Any ideas on what to look at? Remember I probably need some detail (pics would be awesome) since I've never dabbled in brakes before. Thanks guys.
