A system and method for controlling wheel brakes on a trailer in a tractor-trailer are provided. Upon receiving a command to apply a trailer wheel brake, the system determines a speed of the tractor-trailer responsive to a speed signal generated by a vehicle speed sensor. The system also estimates a threshold speed based on a level of friction between the tractor-trailer and a road surface on which the tractor-trailer is travelling. The system then generates a control signal to control delivery of fluid pressure to the trailer wheel brake. The control signal causes delivery of a first fluid pressure to the trailer wheel brake when the speed meets a predetermined condition relative to the threshold speed and a second fluid pressure, less than the first fluid pressure, when the speed does not meet the predetermined condition.
