I would say your master cylinder is going bad or a possible leak in one of your calipers or brake lines. You definitely have a leak somewhere for your pedal to go all the way to the floor. Don't take any chances. If you don't do your own work have someone look at it for you. First thing is to get the car up in the air off the ground. Take all 4 wheels off the car and check your calipers for any leaks. Check the hoses and brake lines. Check under the master cylinder also for brake fluid leakage. If no leaks at the calipers, brakelines or hoses I would definitely suspect the master cylinder for internal problems and would replace it with a new one.

Martin,

I have the same brake problem in my 1991 corvette convertable. They go out when the car gets very hot and then work when the car cools off. What have you done in the past months to cure the problem?
