NOTE: the number of boosters required depends on the brakes, the number of axles and the booster fluid capacity.

WARNING: It is the brake system installers’ responsibility to ensure compatibility between towing vehicle and trailer actuation systems. Various combinations of air/hyd. Or vacuum/hyd. And tow vehicle systems can allow normal maximum working pressure to exceed 1000 psi on drum brakes. Pressures in excess of 1000 psi on drum brakes increase lining wear and can lead to component failure. Make certain your system has the correct boost ratio and brake fluid volume to activate brakes properly.
