Peeps.. Yes, that's exactly what I'm saying.. :)
When I open a single bleeder valve, I can put the pedal to the floor and not have any resistance to the pedal what so ever. I can't push the pedal any farther. I know it's on the floor because I've bleed brakes by myself before and if you don't have a "single person bleeder" setup you have to hold the pedal to the floor and have to have another person CLOSE the bleeder fitting before you release the pedal, or you'll suck air back into the line and defeat the purpose of bleeding the line in the first place.
I used my "THE CLUB" steering wheel anti theft bar to hold the brake pedal and it's as far on the floor board as it can go when I've done it by myself.
So, yes,if I where to back the vehicle out of my garage with a bleeder valve open, it'll just go down the driveway and not have any brakes what so ever..
To me, that tells me that if you lose any part of the line, you won't have any brakes.. But, that's not what I'm completely positive on, since I've never had an on the road brake failure like the OP did... I still stand by my statements of saying that when a bleeder valve is open on a single wheel, the brake pedal goes to the floor..
So, if you wanted to disable someone's brakes, all you have to do is open up (or just snap off) a single bleeder valve on that vehicle and the first time the driver hits the brakes, the pedal will go to the floor and they will have no brakes, other than their emergency brake setup on the rear if they think of that in time..
