The fluid must be leaking out somewhere. Areas to check: master cylinder, front brake flexible hose going from metal line to caliper, front brake caliper piston area, rear brake slave cylinder. Any leaking brake fluid will tend to linger rather then evaporate quickly, brake fluid also damages paint.

If no leaks found follow the brake lines from the master cylinder and look for leaks. It is also possible for the master cylinder to be leaking into the power brake booster. In this case the excess fluid may then be sucked into the brake booster vacuum line and into the engine.

That will all depend upon the nature of the leak. Identify the source of the leak then post back.

Fixing your brake system is pretty straightforward except for the ABS control module, if you have that. Remember, your brake system is not something that you want to have a problem with so you need to have good mechanical skills and you need to be meticulous. Trace down the leak and review the repair explanation in the manual(s). If you are comfortable with the repair, do it. If not, take it to a pro. The on-line manual at the top of this forum is very thorough. Chilton and Haynes also put out good repair manuals. I would use a repair manual to present step-by-step instructions and use the suggestions and DIY posts here to familiarize yourself with the process. It isn’t rocket science but it can be a life or death repair. Be conscientious and you will be fine.

If you do have ABS brakes remember that you bleed them differently than the older brake system. There are repair kits for the slave cylinders but the cost of a replacement cylinder isn’t a lot more. If you’re going to need to bleed your system consider going ahead and swapping out the fluid as well.
