Wilwood DynaPro Calipers 4 Piston VS BAER 2 Piston
My rear calipers with a bigger piston VS BAER's caliper (off of a vetter or f-body) with a 1" or so piston
SSBC 1 1/8" master cylinder VS stock
One would think that my Wilwood set up would have a greater stopping power than that of baer's BUT I'm pretty sure there's more to it than that.
You're right, all that boils down to pressure, pad/disk surface area and torque. The larger surface area of the pistons simply requires more fluid to displace, thus the need for the larger master cylinder. This dosn't mean it has greater stopping power. As long as the proportioning is the same, the brakes should apply the same ammount of pressure to the disks. Of course you could change the proportioning such that a light touch of the brakes locks the wheels, or putting your foot to the floor will stop you in a mile or so even with the stock calipers. There is no stopping power gained from a master cylinder. The difference in piston size will create a more even pressure from piston to pad, but with the steel backing that makes little difference.
The pad/disk contact area is going to be the biggest thing between the two brakes. I haven't seen area measurements from either brake system but I'd guess that similar sized systems would have similar pad sizes. Maybe that's not correct though.
Lastly torque generated by friction would theoretically be greater (meaning better stopping power) from the Baer system, having an extra 1" in diameter. However, I understand that Baer's system is the same between their 12" and 13" kit sizes (having called and asked about caliper fitment personally,) the only difference being the disk size. So we can probably assume that the caliper position, and therefore the torque generated by each system is about the same, having been built for a 12" rotor.
What did I just say? They are probably about even.
