I am trying to replace my master cylinder and the 12mm nut that holds the clutch pipe in will not move, it is rusted over. (cause I know it is tightened to 14lbs so it shouldn't be too hard to free) I sprayed rust eater and PB grease on it, let it sit for a day, and I tried it and rounded the nut . The space is way to small for vise-grips, does anyone have any ideas? I really need it replaced and I can't drive my car until it is. Thanks a bunch!!

 

My suggestion..get the Craftsman stripped bolt socket set. It is kind of expensive but trust me...it will be worth it. You WILL use them again.

That sux man, mine were pretty easy to get off. That one in the corner was hard to get back on though.

Good luck.
