Abstract
A surge brake actuator is disclosed. The actuator includes an actuator housing and a coupler housing movably engaged within the actuator housing. Upper and lower coupler slide channels formed from a plastic material are releasably connected to the coupler housing and contact the actuator housing. The plastic coupler slide channels reduce frictional loss and provides superior brake actuation output when the coupler housing retracts into the actuator housing during braking. The surge brake actuator includes a push rod assembly that also provides superior brake actuation output to the actuator and can engage the actuator during a breakaway event. The surge brake actuator includes a releasably engagable reverse lock that prevents brake actuation while the towing vehicle moves in reverse.
