You just reminded me of the fact that I drove a car with a leaking brake caliper to the dealer for a warranty repair like 20 years ago. Lots of engine braking and gently using the hand brake in non-emergency slowing down, just in case using my brakes like normal would lose me too much brake fluid.

I can't believe I did that shit. I was careful and took the slow streets and didn't have any close calls but damn.
