Brake problem! . . . what is it?

'01 F-350 SD w/ PS. Just today, out of nowhere and with no warning, I applied brake and the pedal went to the floor! At first touch of the pedal it felt like there would be normal brake but immediately softened and pedal went to the floor. Still barely had enough brake to not hit somebody. Drove home (gingerly) and have been scratching my head. Fluid is normal.

What could it be? And how do I know?

Brake Update!

I found the problem (area). RR caliper has fluid running out of it. ??!!*^#!?

Is it possible that the pads can get so low that fluid leaks out of the pistons?

Not that I've seen. Probably should just get a rebuilt caliper to replace it.

No. You would have the metal backing plate on the back of the pads riding on your rotors before that. You've either got a faulty/poorly made caliper w/ cheap seals, the seal was installed incorrectly, or your brakes have gotten so hot that it cooked the seal and blew out. Just getcha a rebuilt one and check your hose for cracks.
