nailer Brakes If your trailer weighs more than 1,000lbs. (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 toinstall, adjust and maintain them properly. Your trailer brake system can tap intothe vehicle's hydraulic brake system only i f , 0 The trailer parts can withstand 3,000 psi (20 650 kPa) of pressure. The trailer's brake system will use less than 0.02 cubic inch (0.3 cc) of fluid from yourvehicle's master cylinder. Otherwise, both braking systems won't work well. You could even loseyour brakes. 0 If everything checks out this far, make the brake tap at the port on the master cylinder that sends the fluid to the rear brakes. But don't use copper tubing for this. If you do, it will bend and finally break off. Use steel brake tubing. If you have a rear-most window open and you pull a trailer with your vehicle, carbon monoxide (CO) could come into your vehicle. You can't see or smell CO. It can causeunconsciousness or death. (See "Engine Exhaust" in the Index.) To maximize your safety when towing a trailer: 0 Have your exhaust system inspected for leaks, and makenecessary repairs before starting on your trip. 0 Keep the rear-most windows closed. 0 If exhaust does comeinto yourvehicle through a window in the rear or another opening, drive with your front, main heating or cooling systemon and with the fan on any speed. This will bring fresh, outside air into yourvehicle. Do not use MAX because it only recirculates the air inside your vehicle. (See "Comfort Controls'' in the Index.) 4-49
