Trailer Brakes

Because the vehicle has antilock brakes, do not try to tap into the vehicle’s hydraulic brake system. If you do, both brake systems will not work well, or at all.

Does your trailer have its own brakes? Be sure to read and follow the instructions for the trailer brakes so you will be able to install, adjust and maintain them properly.
