If you will be pulling a trailer that, when loaded, will
weigh more than 4,000 lbs (1 814 kg) be sure to use a
properly mounted weight-distributing hitch and sway
control of the proper size. This equipment is very
important for proper vehicle loading and good handling
when driving. Always use a sway control if the trailer
will weigh more than these limits. You can ask a
hitch dealer about sway controls.
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer to help prevent the tongue from contacting
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.
Never allow safety chains to drag on the ground.
If your trailer weighs more than 1,500 lbs (680 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:
• 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 your vehicle’s
master cylinder. Otherwise, both braking systems
won’t work well. You could even lose your brakes.
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. If you do, it will bend and ﬁnally break off.
Use steel brake tubing.
