Question:
What is the bolt circle diameter? My old brake is 4inch measured from top left bolt to bottom right bolt. Also, what is the pilot hole diameter? Mine is 3. I believe those dimensions are standard but please confirm. Thanks!

Expert Reply:
The mounting holes for brake assembly # AKEBRK-35L are indeed 4 inches diagonally from the center of one to the center of the other. Side to side or top to bottom the holes are spaced approximately 2-7/8 inches apart on center. The pilot hole is approximately 3 inches. You are correct, those are fairly standard.
The matching right assembly is # AKEBRK-35R.
