I improperly installed a master cylinder. This punctured a hole in the cylinder. I didn't realize this until I pumped a gallon of brake fluid into my booster. How do I get it out?

You'll need to remove the booster from the fire wall of the vehicle, then drain it out, then use some acetone to clean it out. Let it dry, then re-install. If it continues to work correctly, you're in business. If not, you'll need to buy a new one or at the very least, one from a wrecking yard as a replacement. Unfortunately, you probably won't know if it's still going to work until you get it back installed. More than likely, there will be either two or four bolts on the fire wall. Could be inside the passenger cabin to get access or might be in the engine compartment. You'll also need to disconnect the booster from the brake pedal, but that's usually just a rod with a pin/clip arrangement. Really not anything too difficult, but can be a pain in the butt on some models (depending on access space).
