Brake pedal loses tension

When I was pressing down on the brake pedal in my '94 Chevy S10 the brake
pedal briefly lost tension and went striaght to the floor with little
braking action. Quickly, it regained tension and braking resumed. It has
worked fine since.

What would cause this and should I be concerned?

Get the brakes inspected, a pad may have sheared off.

That usually is a polite warning your brake master cylinder is about to
fail. When it fails completely, which could happen 'very' soon, you
will have no brake pedal so if you drive it at all make sure your
emergency brake works and you know how to use it to stop.

It also could be a sign you have leaked out all the brake fluid so it is
worth looking at the level in it or as another poster mentioned a pad
could have sheared off. When ever I have had a pad shear off, the pedal
dropped like that, but it made a horrendous noise like fingernails on
chalkboard on steroids.

No, that noise was me.
