Cool.About how far in did you push the wire?I've never had to do that, yet anyway.(Knock on own head.)
The drill hole is about the thickness of the metal housing of the master cylinder and once it is clear u will feel the wire moving freely in it without any resistance. Only thing that one should be careful of is Not to enlarge the hole using a thicker wire or gouging the bore of the hole. There has to be a better way to clear it up other than using a wire.
When you look into the Brake fluid reservoir, there are two drilled holes, One will look through and the other one looks blank. It is the blank one that has a tiny hole in it that one got plugged. Hope that helps!!
