Sounds like you have a bad brake booster. That is what the master brake cylinder is attached to. Booster has a vacuum line going to it that goes to the engine and air is being pushed back to engine when brakes are applied because the brake booster is bad.

Now as far as the head lights being turned on and it happens can not answer that one.
