cable aligns directly to the center of the pulley wheel 
(Figure 5).

  If the cable is not directly in line to the center 
of the pulley wheel it may be pulled off the wheel 
at any time while the vehicle is being driven or 
while it is being towed. This will lock the brakes. 
  If the vehicle is being towed this will result in 
non-warranty damage to the brakes and tires, as 
well as other consequential damage. If the vehicle 
is being driven a loss of vehicular control and/or a 
collision may occur.
  Failure to align the cable directly to the center 
of the pulley wheel may cause property damage, 
personal injury or even death.

  

Note: if you switch the L-shaped clamp from one 

side to the other, it may be necessary to adjust the 
position of the pulley slightly to the left or right to com-
pensate for the width of the brake pedal arm.

    

Note: ideally, the pulley should be attached so 

that the cable runs parallel to the brake pedal arm, 
as shown in Figure 1. If the design of the passenger 
compartment or other constraints prohibit this, the pul-
ley c an also be 
mounted at an angle.
  However it is mount-
ed, the cable must be 
directly in line with the 
center of the pulley, 
as shown in Figure 5.

• Do not double-

w r a p   t h e   c a b l e
around the pulley for any reason. If the cable is double-
wrapped around the pulley, it may ‘jump the tracks' 
when the vehicle is being driven, as shown above, 
which will lock the brakes.

Do not double-wrap the cable around the pulley.

  Otherwise, the cable may wrap around the pulley 
while the vehicle is being driven. This will lock the 
brakes. 

Failure to follow these instructions may result in 

a loss of vehicular control and/or a collision, which 
may cause property damage, personal injury or 
even death.

The pulley must be attached directly to metal — if

the mounting location is carpeted, a section large 
enough for the pulley must be removed.

The pulley must be mounted on a relatively flat sur-

face (Figure 6).

CAUTION

  If the pulley is not mounted on a flat surface, the 
pulley bracket may be bent when it is attached.

Plan the installation

continued from preceding page

  If the vehicle is equipped with brake pedal pre-
sets, install the cable and brake pedal clamp as-
sembly with the brake pedal as close to the driver’s 
seat as possible. Make certain that the brake pedal 
is at that position when towing.
  As an option, the brake pedal may be moved to 
the desired position and disabled. Do not rely on 
a mental note to never move the brake pedal.
  Failure to follow these instructions may cause
unintended braking and eventual brake failure, 
which may result in property damage, personal 
injury or even death.

Look for a mounting location for the pulley on the

firewall that meets the following conditions:

The pulley (Figure 1) must be positioned directly in

line with the L-shaped brake pedal clamp so that the
