Effective radius of front brake rotors is measured from center of front brake pad to center of front brake rotor. In other words, it is the distance from rotor-center to halfway the swept area of the rotor.

More accurately but less easy to measure: it's the distance from rotor-center-line to center line of caliper piston(s).
