Not So Power Brakes, Help!

I first thought that but I check it and it does not leak and I started the engine with master cyl. off and the booster works very smoothly. I did some reading and I will be looking for a 7/8 bore master cylinder to replace the one I have. I came home after work and pulled it off completely, it is not a one inch but a 1 and 1/8 inch. The lousy lever arrangement by year one is really bad to the point that the booster really has to work to make things happen. Reducing the bore should take care of the problem. We'll see. I got the Careon online parts book and have been looking for something. I should be able to find something and order thorough OReilly, hopefully?
