Review on Raybestos MC39544 Professional Master Cylinder by Drew Baron

The MC39544 was a huge disappointment in my automotive setup.The supposed professional-grade master cylinder simply did not perform up TO par, with stopping power severely hindered by a flawed design. It looks like it will work great on paper, but in practice, it simply falls short. On the plus side, it was relatively easy to install. Unfortunately that does not make up for its lack of reliability and function..
