Activator II Brake Controler Problem

    I have a hydroseeding unit on a dual axle trailer with brakes on all 4 wheels.
    The trailer is new and I it trailer for about 3 months with the output setting on the controller at about 3-4 with sufficient braking power. Then one day I hooked up and I had to boost the output setting all the way up to 8 to feel the brakes even working. I can't see why such a big jump over night.

    This year before I started using trailer again I adjusted all the brakes until I heard slight brake pad rubbing against the drums. When I hooked trailer back up I tried the brakes again and it did not make a difference in the output setting, I still need to keep it at 8 to feel brakes and all the way up to 10 to lock them up.

    I can't figure out why all of a sudden the output needs to be so high, I have it installed in a 2004 Toyota Tundra. The trailer place hooked it up under the dash with the harness that was supplied in the glove box when I bought the truck.

    Any suggestions????

    I was trying to say the trailer is new and I had been using it for only about 3 months.

    Also when the controller output is set to about 9 or 10 I can hear the brakes humming.
