Trailer Brakes
A loaded trailer that weighs more than 450 kg (1,000 lbs) needs to have its own brake system that is adequate for the weight of the trailer. Be sure to read and follow the instructions for the trailer brakes so they are installed, adjusted, and maintained properly.
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.
