No, that makes sense. The booster hasn't been harmed (yet) by the presence of brake fluid. And the MC is working OK - it's just leaking fluid from its rear seal.

You could run this way forever as long as you added brake fluid periodically - sort of like dealing with an engine that burns/leaks oil but otherwise has good oil pressure and compression.

The issue is that eventually the brake fluid will damage the booster diaphragm. At that point, your brake pedal will become harder. And of course, you look silly with all that white smoke on every hard turn!
