03 spectra leaking brake fluid

I have an '03 Specta that is leaking brake fluid. Started out a small leak and is now a big leak going through a half of bottle of brake fluid in a week. Any ideas? Thanks!

Give some idea of where it's leaking, front, rear middle of car???????????

Right under the front of the car.

If there's fluid on the wheel or tire I'd look at the wheel cyl. on that corner.

Basically let gravity be your initial guide. Look straight up.
