Representing over five years of product development and three years of continuous testing, this hydraulic brake actuator has a unique all-aluminum master cylinder that incorporates the shock absorber into the master cylinder assembly. This provides the tow vehicle operator with a warning signal when the brake fluid is at a low level. In addition, the oversized master cylinder provides the higher pressures required to run disc brakes and the added brake fluid volume to run both tandem and tri-axle configurations. Higher pressures mean quicker stops when using traditional drum brakes. Fits trailer frames up to 3"W x 5"H and accommodates 2" hitch balls.
8,000-lb. actuators come with a 2" hitch ball.Click here
