1.
Find a suitable location at the front of the towed
vehicle to attach the preassembled male quick coupler
(Figure 10). Choose an area within easy reach, with
a surface of sufficient strength to hold the mounting
bracket firmly in place.
Do not attach a female quick coupler at the front
of the towed vehicle. the female quick couplers
have an internal check valve to prevent air from
escaping. if air pressure is not released, the brake-
master pedal clamp will not retract when the system
is activated, which will cause severe brake system
damage, or a brake fire, as well as other conse-
quential, non-warranty damage.
failure to follow these instructions may cause
property damage, personal injury or even death.
2.
Attach the bracket with two of the supplied ¼" nuts
and bolts, with the male quick coupler pointing away
from the towed vehicle.
Note: the weather covers will prevent dirt or debris
from entering the lines. Keep the fittings covered when
the braking system is not in use.
3.
Connect one end of the air line to the male quick
coupler compression fitting (Figure 10) — first, if neces-
sary, trim the end of the air line, to make a smooth and
straight cut. Then slide the compression nut and the
ferrule (Figure 10) over the air line. Position the ferrule
¼" from the end of the air line.
Next, slide one of the brass inserts (Figure 10) into
the end of the line.
Note: if the brass inserts are omitted, the fittings will
not be airtight.
Now, push the air line into the compression fitting,
as far as it can go. Then push the ferrule into the com-
pression fitting, and tighten the compression nut onto
the fitting.
Note: if the compression nut is overtightened, the fit-
ting will not be airtight. After completing the installation,
check all the fittings for air leaks — see “System test.”

Tape the open end of the air line. Then, route the air
line from the male quick coupler to the break away air
reservoir, avoiding moving parts, sharp edges or “hot”
components such as the engine or the exhaust system.
Do not kink the air line, or bend it to the extent that it
crimps or creases.
Note: if the break away system was not installed,
route the air line through the engine compartment and
through the firewall — see step 7 below.
Do not position the air line closer than two feet
from any heat source. the heat will soften the plas-
tic, which will cause the air line to rupture.
if the air line is ruptured, the supplemental brak-
ing system will not function.
Do not kink the air line, or bend it to the extent
that it crimps or creases — air pressure will be sub-
stantially reduced, or blocked entirely, at the kink
in the line.
if the air pressure is reduced, the supplemental
braking system will not function, or may only func-
tion intermittently.
Where appropriate, use wire ties to secure the air
line in place.
5.
At the top of the break away air reservoir (Figure
11), cut the air line to length and attach the open end
to the brass “air in” compression fitting (Figure 11). Use
the same method described in step 3 (above) to attach
the air line.
6.
Next, attach the end of another section of air line
to the brass “air out” compression fitting on the top of
the break away air reservoir (Figure 11 ). Use the same
method described in step 3 (above) to attach the air
line.
7.
Tape the open end of the air line. Then, route the
air line from the break away air reservoir through the
engine compartment and to the driver’s side of the fire-
wall. As before, avoid moving parts, sharp edges or
