It's Saturday morning and after coming home from a short trip Thursday night I was informed by my wife that our daughter's brakes were "on the floor". "The Baby" is 20 and at least she had the smarts to allow more braking distance to stop the car sheesh... I think her guardian angel was applying the brakes... bad daddy for sure.
Anyway, yesterday I checked the master cylinder and no fluid... small puddle about 3" in dia under her parking spot, but not a master cylinder full IMO. Moving along, I filled the reservoir and still no pedal, the car was braking on the floor and the pedal wouldn't pump up, but got enough brakes to get the car in the garage. Jacked it up at each corner, one at a time and popped the wheels off... everythimg looked dry at the calipers and flex lines. One had a nice gouge in it which will call for some S/S replacements... of course... but no leaks. No leaks at those 2 little hoses off the ABS module either. My wife pumped the brakes while i inspected and the reservoir maintained it's level that I refilled it to.
Gonna jack it up this morning after a cup of coffee, bleed the brakes and hopefully get some pressure and the pedal up to see if I spot a leak in one of the hard lines or?? Any of you guys have an idea?

Thanks and Yo,
Rod
