0 If you'll be pulling a trailer that, when loaded, will weigh more than 2,000 Ibs. (900 kg), be sure to use a properly mounted, weight-distributing hitch and sway control of the proper size. This equipmentis very important for proper vehicle loading and good handling when you're driving. Will you have to make any holes in the body of your vehicle when you install a trailer hitch? Trailer Brakes If your trailer weighs more than 1,000 lbs. (450 kg) loaded, then it needs its own brakes -- and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you'll be able to install, adjust and maintain them properly. Your trailer's brake system can tap into the vehicle's hydraulic brake system only if: 0 0 If you do, then be sure to seal the holes later when you remove the hitch. If you don't seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle (see "Carbon Monoxide" in the Index). Dirt and water can, too. The trailer parts can withstand 3,000 psi (20 650kPa) of pressure. The trailer's brake system will use less than 0.02 cubic inch (0.3 cc)of fluid from your vehicle's master cylinder. Otherwise, both braking systems won't work well. You could even lose your brakes. 0 Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer's recommendation for attaching safety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig. And, never allow safety chains to drag on the ground. If everything checks out this far, then make the brake fluid tap at the port on the master cylinder that sends fluid to the rear brakes. But don't use copper tubing for this. I f you do, it will bend and finally break off. Use steel brake tubing. 4-47
