Lost Brake Pressure

I have a 87 YJ 4.2L manual. The jeep was parked for about 2 months. I wanted to use it today, but all of a sudden there was no brake pressure. Is this possible? Do I have to bleed it? Thanks for your help.

There must be a leak somewhere in the system. I have let cars sit for a couple of years and no problems so something is bad.
Check the master for leaks at the firewall inside the cab.
Check the fronts and the rears by looking for any drips on the bottom of the drums or sweating on the backing plates.
Its a closed system when fluid goes out even a t5iny amount air gets in.

OK, I found the leak. It's in the front passenger side hose/wire that's coming from the brake reservoir. So do I have to replace the whole hose/wire or is there fix for this. Thanks.

I'll take a picture as soon as the rain stops. It's the steel brake line that connects from the front passenger will to the brake fluid reservoir. It looks like I have to replace it because it's really rusted. Thanks.
