Disk Brake Mounting Standards (Avid/SRAM)

[CaptnCanary]

Hi guys. I'm doing the CAD design work for a battery powered vehicle to take part in a 4 hour race. The competition is called 'Greenpower'. We are using bicycle disk brakes on the front wheels of this car. Specifically the Avid BB7 MTB cable disc brakes with 74mm post mount caliper and 6 bolt mounted disks. I have found that the 6 Bolt PCD is 44mm but I have so far been unable to locate a CAD model of the Caliper or any standards telling me how to mount the Caliper relative to the Brake Disk, so that it is positioned correctly. If anybody could point me in the direction of the relevant standards for mounting this type of caliper or even better, point me in the direction of a CAD model of the Caliper we are using, I would be most grateful.
Regards
Steve

IS2000 is the standard you're looking for.
Here is the PDF with the standardized dimensions for both front and rear mounts:
