Tie Down's 750E Actuator Works by the surge or push of the trailer toward the tow vehicle. This automatically synchronizes the trailer brakes with the tow vehicle axle brakes. When the trailer pushes against the tow vehicle. the actuator telescopes together and applies the force to the master cylinder, supplying hydraulic pressure to the brakes. The built in dampening shock absorber retards the telescoping shock against the hitch ball.
The Model 750E actuator is completely assembled and ready to bolt into place. Manufactured for tongue sizes 3"x 3", 3"x 4", 3"x 5"
Features:
Use only DOT-3 heavy-duty brake fluid in the Mode l750E actuator. Use pressure type brake bleeder to bleed brakes.
