Vette(s): 1986 convertible, bright red, white top, red interior
Half way through my Sunday afternoon drive I developed a brake problem in my 86 Corvette convertible. I went to stop , the car stopped but the brake pedal suddenly felt spongy
and slowly sank to the floor. The brake warning light also came on when the pedal got to the floor.
I pumped the brakes, the warning light went off and the brakes worked normally. However if I held my foot on the pedal it would go to the floor and the light would come on again. I made it home without incident by pumping the brakes each time I needed to stop.
When I was home I immediately checked the reservoir for brake fluid and it was full! I checked each wheel and the area around the reservoir but could detect no sign of leaks.
My gut instinct tells me that the master cylinder has failed. I would like to confirm this with your experiences before I order a replacement Master cylinder.

I rebuilt mine a few years ago with a kit I got from NAPA, easy straightforward project. I didn't get much warning like you did, mine went out all at once and pumping the pedal barely made the car slow down. Fortunately I was only 2 or 3 miles from home but it was a nerve racking ride
