Hey Martin,
From what you're describing it sounds like you have 3,500 lb axles so I recommend using the Hydraulic Trailer Brake Kit # AKFBBRK-35 because they have the free-backing feature so your brakes don't lock up when you back up.
If your actuator has the reverse lockout, then you can use the etrailer Hydraulic Trailer Brake Kit # AKUBRK-35 which is the same thing, just without the free-backing feature.
