I had to change the front driver brake caliper on my wife’s car yesterday because one of the pistons froze. I wanted to remove the old caliper, bring it to the store so I could take care of the core charge in one trip and not have to go back later. It has a banjo fitting for the brake fluid and I said to myself, “Self, how can I stop the fluid from draining out, while I make the trip to the store”. After thinking for a few, I thought of the foam earplugs that you crunch down between your fingers and they expand. So I did - I squeezed the earplug, stuck it in the banjo hole and viola! It expanded and at least slowed the drip. I put a container under it to catch anything that dropped out. I made the trip to the store and when I returned, I realized that brake fluid kinda dissolves that foam. The plug was still there and mostly doing it’s job, but it fell apart when I tried to remove it. And it turned the brake fluid orange that drained out. So I guess it was mostly successful, but not what I expected.
