1.
Route the cable as planned and attach the air cyl-
inder with the band clamp using a 3/8" self-tapping
screw, as shown in Figure 12.
It's also often possible to cable-tie the cylinder se-
curely to an existing vehicle loom.
2.
If necessary, use one of the sliding clamps (Figure
8) to secure the cable housing in place.
3.
Attach the 1/8" air line to the air cylinder — press
one end of the line into the port on the air cylinder
(Figure 12) until it bottoms out. Route the air line to
the controller and, if necessary, trim the line to length
— make a smooth, straight cut — then press the other
end of the line into the port on the controller (Figure
12) until it bottoms out.

1.
A 1/4" of free play is necessary to ensure that the
towed vehicle’s brakes will not be applied unless the
supplemental braking system is activated.
If you do not have 1/4" of free play, adjust the cable
by moving the retaining nut and locking nut forward or
backward on the adjuster sleeve. This will remove or
gain up to 1/2" of slack in the cable.
2.
When the ball at the end of the cable is clearly vis-
ible (Figure 4), tighten the nuts with two 1/2" wrenches.
3.
If you are unable to adjust the cable sufficiently,
Adjust the cable for ¼" of free play
you must reposition either the brake pedal clamp and/
or the cable anchor bracket.
CAUTION
Adjust the cable to allow 1/4" of free play, as
directed. Otherwise, the towed vehicle’s brakes
may be applied continuously, which will cause
severe tire and brake system damage. Other
consequential, non-warranty damage may also oc-
cur.
Attach the cable anchor bracket
continued from preceding page
CAUTION
Do not allow sharp bends near the cable anchor
bracket. Tight bends will create internal friction
between the cable and housing, reducing the ef-
ficiency of the braking system, and may cause non-
warranty damage.
2.
Move the cable anchor bracket forward or back-
ward until the ball at the end of the cable is clearly
visible, as shown in Figure 9. This will allow 1/4" of
free play in the cable.
3.
With two of the 3/8" self-tapping screws, attach
the cable anchor bracket.
4.
Check the towed vehicle’s brake lights to make cer-
tain that attaching the cable anchor bracket has not
caused the brakes to be applied. If they have been,
readjust the brake pedal clamp or the adjuster sleeve
(see the next section).
