Hey Philippe, in my opinion the Hydrastar disc brake setups are the best because they have the best and most reliable electric over hydraulic actuator. We've found it's the most reliable and quickest reacting. So for a triple 7k axle setup you'd want the part # HSE7K-TR1 for a hub/rotor setup or the part # HSE7K-TR1SO if you preferred a slip-on style rotor that fits over idler hubs.
Both of these are for 1/2 inch diameter wheel studs. If you have a different size stud let me know and I'll see what you'd need.
