Brakes gone, need possibile diagnosis..., No brakes, but plenty of fluid. Options

Yeah, if you check the tranny forum... you'll know my clutch is gone too. The night before, I was stopping for a deer when my brake pedal went to the floor. Lucky me.

Master and slave cylinders are both full. I still have some stopping power if I push the pedal all the way down. I haven't had any symptoms of failing brakes, they've been fine for awhile now. Just all of a sudden they're gone. Shoes replaced around 8 mos. ago, and front pads are still in great condition.

Edit: Sorry for the noobish question, but brake assemblies aren't my strong point

if you are CERTAIN that your brake system has NO air in it, then you need to possible replace your master brake cylinder, $200 by the way i just did mine. After that if you problem continues, then you need new wheel bearings, i had the same prob after the new mbc and replaced the wheel bearings and now its fixed. Whats happening is that after a slight turn, the free play in the bearings allow the rotor to move more than normal, and it pushes the pistons back inot the caliper, so the next time you need to brake you need just about i full pedal travel to push them back out and begin clamping on the rotor again. Good luck

P.S. Make sure to bleed the whole brake system if u replace the mbc and also the MASTER BRAKE CYLING itself needs to be bled, which i found out the hard way.
