Experience faster response time with the Hydrastar Electric Over Hydraulic Actuator for Drum Brakes - 1,000 psi. Simply apply the brakes in your tow vehicle and the trailer brakes will be triggered, eliminating the need for manual locking. Plus, you have the ability to intentionally activate the trailer brakes while reversing, thanks to the manual override on the brake controller.

Brake controller (sold separately) is required to send signal from tow vehicle to actuator when brakes are applied

7-Way trailer connector (sold separately) is needed to transmit signal from brake controller
