So i'm driving around and my brakes are working perfectly. I go to the mall and turn the car off. 15 min later I go to start my car, BTW its an 87 turbo Auto. I go to step on the brakes to put it in reverse and the pedal goes down to the floor. As if I had no brakes. As I let the car warm up, the brakes began to feel normal again. This has never happened before.
What could have happened?
