Which brakes are you using, front and rear (single or dual piston calipers, rear brake size, wheel cylinder bores)? Do you have a firm pedal? Is it high or low? Which Monza master are you using? '75 Monzas used the Vega front calipers, so they used the small (3/4" bore) Vega master, '76-'80 used the larger bore master. S-10s use a 24mm bore master, which is close to a 15/16" bore. Did you bench bleed the master before installing it?
Too small of bore master will give you a low, spongy pedal, too large will take an enormous amount of pedal pressure to achieve acceptable braking performance.
