My brake fluid reservoir was empty, my ABS light came on. I filled it drove 7 miles home and it's empty. I don't see any visible leaks. What could it be?

Look on the inside of the wheel one of them might be wet. it can also leak from a cracked brake line onto the road. Before you move the car the next day look under the car to see if any leaked onto the road. it can also leak into the brake booster from behind the master cylinder where you cant see it.

Yep I agree with MECHTRIX, I have seen the back of the brake master leak and fill up the brake booster. If you cant find any leaks unbolt the brake master from the booster for inspection.
