After researching the installation instruction I found out that I was not happy with the modification required to my original master cylinder check valve along with requiring additional valve to make these brakes work properly. After further research I found a forum online that showed that another guy had bought the same kit for the same car as mine and the brackets would not work. At that point I gave up on the disc brake conversion and decided to rebuild my stock brakes. If there was further investigation done on the fitment on the 51 Buick Super it might save the next customer the grief of returning the wrong part. Customer service worked great with me on my return, and I will remain a Speedway Motors customer for that reason. Bob K.

I need a master cylinder as well, and this kit does not come with one. What can I use that will be compatible with this?
