I had a similar problem on a recent build. I used the normal Corvette 1 inch master cylinder but had little or no rear brake pressure. I went through the NAPA book and matched the rear wheel cylinders and master, from a Maverick as Jax previously stated. I think it was a 7/8 or 13/16 master. I got the brakes bled with the new setup. With the 1 in Corvette master on another build a while back it took way too much pedal effort to stop the car. I swapped that master cylinder out to the smaller diameter master and it will stop on a dime now. Everything need to be matched, master cylinder, wheel cyl's and take the weight of the car into account also.
