I just purchased a 97 F150 XL 4.6L V8 a couple weeks ago.

I bought this truck and it drives great but with a couple issues that I can't figure out how to fix and it is driving me to punch babies.

The ABS light and the Ebrake light are always on and no matter what I do they will not go off. I've tried several things but to no conclusion.

-Replaced all the front brake pads.(three days ago)
-Replaced all the rear drum brake shoes and springs including one of the wheel cylinders because I didn't like the way it looked. (three days ago)
-Bled the entire break system.(three days ago)
-Replaced the brake sensor located on the rear differential.(yesterday)
-Replaced the speed sensor on the transmission extension(today)
-Replaced the rear backup bulbs because they were burnt out.(today)
-Replaced the rear brake bulbs just for kicks.(today)
-Rewired the license plate bulbs because they were corroded.(today)

Is there anyone out there who can help me because I am at my wits end.
Thank you in advance
