It it did was it a good pedal when cold ?
The system is split front to rear, have you tested that both systems work ?

Yeah the pedal pumps back up. What do you mean by testing both systems?

For safety the brake system is split, front and rear. The idea being that if one system fails, a front brakehose splits for example then the rear system will work independantly of it ensuring you can still stop.
For your pedal to go to the floor, both systems must have failed, either together, very rare, or one system was inneficient already (rear ??) and as a result you have overheated the front.
It is not uncommon for '86 calipers to bind on the sliders, not generally noticeable when the brakes are cold but when they heat up they expand, bind the pads on and boil the fluid. The easiest way to check for this is to take the car out on a run, apply the brakes a few times and then drive a couple of Kilometers without using the brakes, roll to a stop without the brakes, get out of the car and feel the wheels, they should all be cold.
