If the trailer brakes are actually locking up the wheels - trailer wheels skidding - than you have actually lost some braking capability. A wheel skids when the rolling resistance is more than the sliding resistance. When a tire is sliding, there is no control until it starts rolling again. That is what anti-lock (anti-skid) brakes on your tow vehicle are all about - providing maximum braking without letting the tires skid.

The theory is you only have them just barely able to lockup when you manually activate them fully with the lever at low speed....25MPH or so. By doing this with the manual lever, they should never lock up when controlled by the controller itself.
1. Connect trailer to tow vehicle.
2. With engine running hold manual full left and set Power Knob to indicate approximately 6.0
3. Drive tow vehicle and trailer on a dry level paved surface at 25 mph and fully apply manual knob.
3 If trailer brakes lock up: Turn power down using power knob. If braking was not sufficient: Turn power up using power knob.
4. Repeat Step (3) until power has been set to a point just below wheel lock up or at a sufficient force as to achieve maximum braking power
