67 dart front disc upgrade made..still not right

Came in here late & saw that problem is fixed. Lager M/C bore= harder pedal effort to move the smaller brake pistons & therefore actually less braking power. You're moving more fluid at a faster rate per inch w/ the larger m/c into a small area(caliper, wheel cylinder). The brakes apply quickly but you cant move fluid faster into the smaller cavity(caliper, w.c.) than it can handle so you have increased pressure, but not increased travel on the working end. So less braking force. Think of it like hydraulic gear ratio.
