If the pedal went to the floor when you blew the line you may have pulled a wire off the switch or something like that.

does a 94 GMC have a duel master cylinder? If it dose I would not think the pedal went to the floor. Are you sure you had brake lights before, sometimes we do not know that answer, and after working on a system we find more stuff wrong. I would look at the brake light switch, could be out of adjustment, or bad, it is a simple system.

just cause the tails work dosnt mean the bulb is good they are duel filament bulbs... also if its the same style as the 99 i know the boards behind the bulbs are prone to go bad

Tail lights work, turn signals work then both filaments in the bulbs are working and the wiring to the rear of the truck is good (turn signals and brake lights use the same wiring from turn signal to the rear). The problem lies in the brake light switch or the wiring to or from the brake light switch. Check that you are getting power to the brake light switch and then check for power from the switch when the pedal is depressed (switch activated). If none, bad switch: if power present, bad turn signal switch. As stated, it is possible you damaged the brake light switch or displaced it from it's normal position when you bottomed the brake pedal.
