The brakes are not in the cad, but the mounting holes are. We used avid bb5s on this year's, and last year's robot. Adrian designed custom hubs that we copied for this year. The hubs use a standard bike hubs bolt pattern with a .5'' hex hole in the center. We actuated the brakes by pulling a bike cable with a piston. The pistons have a clevis with a hole drilled in to it in order to fit the end of a mountain bike cable. We were not sure where we would have room to mount the pistons so we designed a sleeve that threaded on to the front of the cylinder that would allow us to mount the piston wherever we wanted without needing to be rigid. The sleeve has enough room for the piston to fully extend with the clevis and a small hole in the end for the cable to go through, but not large enough for the cable housing. The brake actuates by having the cable housing be a fixed length touching the end of the piston sleeve and the end of the brake while the cable is pulled though it.
