The only difference between single and dual servo hydraulic drum brakes is that dual servo will provide more force while in reverse than single servo. That said, it's not much and most really don't use their brakes a ton in reverse so single servo like the Hydraulic Trailer Brake Kit part # AKFBBRK-35 are far more common.

I have attached a list of our hydraulic brakes below, if you need help picking out a set I would just need your axle capacity.
