The friction assembly that holds the pedal down is broken. Replacement of the complete e-brake pedal assembly is required. Your local Chevy dealer can get you that part for aprox $70 or you can try getting a used part from a salvage yard.
Adjust or replace the stoplight switch at the upper end of the brake pedal under dash area
Brake booster can leak - both small hard to detect leaks & big leaks (easy because if it leaked a lot) your brake pedal would be really hard to push - just like it is when the engine is off & you pushed on the brakes. If a small eak sometimes harder to tell if it's bad - as brake pedal may "slowly" go down when you push on it. If it is bad the pedal will get harder to push. start engine leave in park hold brake pedal down for 1 minute, if it starts to go down then there is a leak somewhere otherwise it shoukld stay where it was
