Pedal goes straight to the floor with no pressure at all. It has been sitting for 20 years. I'm not a mechanic please help.

Please check the brake fluid first, if it is okay, I would start by changing out the brake master cylinder.

Here are two guides that should help us fix the problem:

Please go over these guides and report back.
