Without knowing weight bias, you can’t really say it should be either way. I can tell you that my own car, that had countless hours of experimenting on the brake system, was as well balanced (brake wise) as any car I had ever driven. It was a mish mash of odd parts that worked in orchestra on a heavy car that had no business going as fast, or stopping as quick as it did. Each front wheel (26” tall Eagle front runner) had 1100 pounds static weight, while the rear (31” 10.5W MT) were at 750 pounds static weight.
The car had 12”dia vented front rotors with wilwood large piston calipers. The rear of the car had 10” drum brakes from a cuda or some such car. The master cylinder was what you would find in a late 80s caravan. Those master cylinders have no built in bias because they are designed for a cross braking application. My adjustable prop valve was in the rear brake circuit. I adjusted out some rear brake until i could skid the car evenly at speed.
