need quick help with brake line/cable no brakes after wreck!

hey guys, well, about three weeks ago, i went riding at TNT Moto. park in Chester, SC. i was coming into the 2nd turn on the Int. track in 3rd gear, and a caught a rut and took a spill, nothing very serious, the handlebars turned into my crotch, but nothing serious. i picked up the bike, with a little help from another guy, and sure enough, a busted brake lever sits there snarling at me. i took off, while passing everyone on the track, and i came to the last turn, they got rid of the berm there and just made it a rough pile of sand. i reached to grab the little stub-of-a-lever, but nothing happened. i tried again, but no front brakes! i hit the rear brakes and gave a guy on a 450 a dry shot of sand( on accident). i might go riding again this saturday and id like to have front brakes. i did see a good bit of fluid on the ground, but i obviously figured it was just gas. i know that bleeding the brakes probably wont help( correct me if im wrong), but, from my experience, brakes dont just instantly shut off, they gradually wear down. any help is appreciated. thanx

hey guys, i forgot to mention after my dad looked at it, he said the brakes arent completely gone, he said the brakes have just a little, incy, wincy, pull. hope this helps. thanx
