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.
Trailer
Brakes
If your trailer weighs more than
1,000
pounds
(450
kg) loaded,
then
it
needs
its
own
brakes
-
and they must be
adequate. Be sure
toread and follow
the
instructions
for
the
trailer brakes
so
you’ll
be able to install,
adjust and
maintain them properly.
Your trailer brake system can tap
into your vehicles’s hydraulic brake
system,
except:
Don’t tap
into your vehicle’s brake system
if
the trailer’s brake system
will use more than
0.02
cubic inch (
0
.
3
~
~
)
of fluid from your vehicle’s
master cylinder. If it
does, both braking systems won’t work well. You
could even lose your brakes.
Will the
trailer
parts
take
3,000
psi
(20
650
kPa)
of pressure? If not, the
trailer
brake system must
not
be used with your vehicle.
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.
