You say "it's not the brake", although both your faults point to it. I don't know what faults 2700 and 2702 are exactly (obviously brake related), but let me ask, is there a brake switch on the brake itself? If so, have you metered the contacts opened and closed? Sluggish to drop the switch contact after a run can generate faults.
Or if no switch is present, have you checked the brake relay itself?
