Can someone tell me the thread size and pitch of the mounting wholes on the Brembo brake calipers? I have not received mine yet but have made the brackets. Thanks for any help. Tony C. P.S. They are the same calipers as R.G.'s 65mm spacing.
 
I believe they are 10 mm bolts. As I remember, I used the same bolts that were previously used to bolt the stock front caliper to the stock foks on my 78SE.

Perhaps better to wait until you receive the caliper, in order to match up the bolt threads.
 
Brembo 4-piston calipers with 65 mm hole spacing has M10x1.25 thread, commonly used on japanese bikes.

Older Brembo 4-piston calipers with 40 mm hole spacing have M10x1.50 thread. This is standard/generic 10 mm coarse thread used for general purposes.
