Did you try bleeding them, might have a pocket of air in the hose. If you did you might have to get new rotors up front, you might of got the front disc shaved down to much.

Last time that happened to me it turned out to be the master cylinder deciding to retire while heading down a hill (strangely enough while I was carrying a bedload of parts to mod that particular truck!)

I 2nd the master cylinder diagnosis. Happened to me, 1 stoplight everything is fine, next light pedal goes to the floor with dash brake warning light on. Luckily I was only a couple of blocks from home and could use the parking brake to stop.
