The pedal sticks down if there isn't sufficient hydraulic pressure to return it. Definitely sounds like air in the system. Now the reason the air is there is because of 1 of 2 things, either the fluid boiled due to fluid contamination that lowered the boiling point, or air entered the system somewhere. The later seems unlikely at this point as if that were the case then fluid could also leak out the same place.
Just bleed it, takes all of 5-10 minutes. Takes more time getting the car jacked up to get access to the bleed screw.
