Pulled a real bonehead move here. I installed the elbows for the brake cylinders without sealant/lubricant a few weeks back and tried to take them out and broke both of them off in the cylinders.
I drilled them out pretty close to the threads and used a pipe thread tap to retap the holes (no, an easy-out didn't work). It worked pretty well and the last bit actually came out with the tap. But, in the end I'm not completely comfortable with the result. So, I ordered two new cylinders (ouch) and will replace these units.
