Techniques of braking a trailer with a trailer braking system. In one example, a controller receives a brake request from a vehicle to apply the trailer braking system, receives a plurality of wheel speed signals from a plurality of wheel speed sensors, and determines a velocity of the trailer based on the plurality of wheel speed signals. The controller determines a wheel speed of one of a plurality of wheels based on one of the plurality of wheel speed signals, compares the velocity of the trailer to the wheel speed to obtain a difference value, and determines that one of the plurality of wheels is unstable when the difference value exceeds a threshold. A braking signal to reduce a braking force on one of the plurality of wheels is generated when one of the plurality of wheels is unstable and when the brake request is received.
