brakes went out, no brake fluid; radiator dry

Can someone please give me a guess as to what is wrong with the brakes and what I might be looking at. Brakes went out and there is no brake fluid or radiator water. I would so appreciate a little advice... Sounds like you have one leaky vehicle.

Here's hoping no one was hurt when you discovered there were NO brakes!

My guess: you have developed leaks in the cooling and brake system.

Another guess: you ignored forming puddles under your vehicle.

Someone has a nasty vendetta against you (as in sabotage).

Fix the leaks, fill the radiator, fill the brake system, bleed the heck out of the brake system, and drive safely! (And carry a baseball bat)
