You drove my '84 and used the brakes, no? On any car, the pedal should NEVER
bottom out - you have a serious problem there neighbour!
Does the pedal 'pump up'? i.e., if you mash it repeatedly does the travel
shorten/pedal become firmer as air in the system compresses?
Otherwise you are having a hydraulic pressure loss which is usually a master
cylinder problem.
When you start the motor with your foot on the brake pedal after having
pumped it a couple of times, does the pedal push back up?
