I attempted (and failed) to replace my master cylinder and brake booster. I ended up putting a lot of brake fluid into my new booster before I realized it. (In fact, in an attempt to determine the problem I turned the engine on a few times. I now realize this was an additional mistake.)
So I put the old booster and cylinder back on and began bleeding my brake lines but noticed my brake lights were staying on. I started the engine in hopes it might correct the issue and a tremendous amount of white smoke came out of the exhaust pipe.
I suspect when I started the engine the first time I sucked fluid from the cylinder that was leaking into the engine. I'm not sure what to do now.
