How do you release a parking brake on a 94 corvette?

Your owners manual explains exactly how to do this. You put the parking brake lever to the floor and, while keeping your foot on the brake pedal to keep car from rolling after parking brake is released, push the button on lever all the way in and while keeping button pressed the whole time, pull up until you get the lever past the notch you locked it in to begin with. Then, without releasing the button, lower the lever all the way to the floor. If done correctly the park light WILL go off. Do not drive the car with this light on or else you will end up with major problems. Hope this helps.
