| The effective radius of a brake rotor is measured from center of brake pad to center of 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). |
