Master cylinder is junk

I installed the booster/master cylinder and was never able to get a firm pedal. I was chasing a leak and replaced many components on my brake system only to discover that there was a casting flaw in the master cylinder. It leaks and won't hold pressure. The unit also sits on too much of an angle which limits the amount of fluid in the reservoir, doesn't seem safe.

I would give this 5 stars if there were instructions included and better instructions available on Speedway Motors site. The product itself was great the people are speedway are great just in this one case the lack of documentation and instructions caused me to have to call in and wait 30 minutes to get a question answered that could have been addressed in documents
