Many years ago I had the hose on the left caliper blow on my 74 Dart SE.
No front brakes at all, but I did have some rear brakes. I would not classify it as having had 100% of my rear brake capacity. But then again, how would I have known? The pedal went almost to the floor before anything happened.
It got me back to the base and I fixed it later.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
