I put in the speed bleeders the other day, well one of them anyway. But all I can say is cool! I have never bled my own brakes before. And these things were made for mechanical morons like myself. Simple as 1, 2, 3...take the old one out, put the speed bleeder in and and flush the system by youself. The only problem I had was the first one I put in the front brake snapped off. It was longer than the stock and looked like it should go in more as several threads were exposed. But my neighbor came to the rescue again. He had the tools to get it out. I put the other one in, carefully, and wahlah! instant and easy brake bleeding. I called Speed Bleeder to order new ones and they replaced the broken one for free. They said they are getting calls of them being a tad too long. But they still work great. I am going to get some for my street bike too. They also make them for your cars if you work on your own. If you are skitish about doing your own brakes, like I have been for years, you absolutely have to get these things. Only $15 for the pair.
