The center hole diameter on the Hayes/AL-KO 12 x 2 Electric Brake Assembly, part # 185100, is 3-1/4 inches (3.25).

This # 185100 brake assembly has the standard 5-bolt mounting pattern.

For the standard 5-bolt mounting pattern the distance between the bolt holes is 2-1/8 inches on center except for the bottom 2 holes. The 2 bottom holes are 3 inches apart on center.
