You completely misunderstand the operation of hydraulic brakes. If there is a break in a closed hydraulic system the entire system is compromised. Not just a particular corner of a vehicle, as you suppose. Last year I broke a brake line at Moab on the left rear corner. All of my Jeep's braking function was compromised until I could replace that one line.

"A typical master cylinder is actually two completely separate master cylinders in one housing, each handling two wheels. This way if one side fails, you will still be able to stop the car. The brake warning light on the dash will light if either side fails, alerting you to the problem."

Hmm. You should have only last half the brakes. At least that's how most vehicle braking systems work. Can't believe Jeep would change that--I always assumed it was federal law ...

I just had the unfortunate pleasure of losing my 2 caliper bolts, which was followed by the pads falling off and the piston, all in the middle of nowhere Nebraska on my way to Denver. Friday night, only auto parts store didn't reopen until Monday. So I pinched the hard line, topped off fluid, thinking I would still have some brakes, but there was nothing. I only
had engine brake and the awesome jk e brake :(
maybe if I had bled the other corners?
Since then I bought a cap for the hardline fitting, so I could cap it off, bleeding it with the cap. And I used a paint pen on the caliper bolts so I visually tell if they come loose

In theory, that is how it is supposed to work, but it doesn't seem to work that way after you lose the fluid.
