When I received this item it was slightly torn, I took it out of the box and inspected it. It seems to be quite solidly made and weighs about the same as my original master cylinder. So I put it aside and let it sit for a week. when it came time to install it, I saw that it was covered in rust; inside and outside. not very big rust but little spots everywhere, i mean everywhere. I didn't want to risk installing it in its current state, so I took the good parts off and put them in my old cylinder. I wish I could say it works like a charm but I can't. What I can say for sure is that it rusts very quickly (you might want to paint it) and now my old cylinder works like new. I kept it anyway because you never know when it might come in handy.
