following conditions are met:

 

 

A.

  Make  certain  that  the  pedal  clamp  is  not  de-

pressing the towed vehicle’s brake pedal — examine the 
brake pedal, and also check the towed vehicle’s brake 
lights, to make certain they are not illuminated.

 

make certain that the pedal clamp is not depress-

ing the towed vehicle’s brake pedal.
  if  the  pedal  clamp  is  pushing  the  brake  pedal 
down, the brakes will be applied continuously when 
brakemaster is connected,  which will cause severe 
tire and/or brake system damage, as well as other 
consequential, non-warranty damage.
  failure  to  follow  these  instructions  may  cause 
property damage, personal injury or even death.

 

 

b.

  When it is connected, the air cylinder must be 

pulled back toward the anchor plate in order to insert 
the safety pin (Figure 4) through the mounting post.

  the air  cylinder must be  pulled back when  it  is 
connected, in order to create sufficient spring ten-
sion to keep the weight of the cylinder off the brake 
pedal. if the cylinder is not pulled back when it is 
connected,  the  weight  of  the  cylinder  may  cause 
the  pedal  clamp  to  depress  the  towed  vehicle’s 
brakes  continuously,  which  will  cause  excessive 
brake wear, brake system damage, or other conse-
quential, non-warranty damage.

 

 

c.

  The pedal clamp must be flat against the brake 

pedal and properly secured with the hairpin clip (Figure 
3).

 

 

D.

  Make certain that there is sufficient clearance 

between the mounting post and the bottom of the seat 
to allow the seat to slide properly.

 

10.

  Once the four conditions in step 9 (above) are met, 

attach the anchor plate. (It may be helpful to remove the 
driver’s seat to facilitate the rest of the installation.)
 

  The  anchor  plate  can  be  attached  on  top  of  the 

carpet, or underneath it.

 

 

A.

 To mount the plate on 

top of the carpet

, first 

use the anchor plate as a template and mark the five 
holes to be drilled.
 

  Before drilling, make certain that the retaining screw 

(at the bottom of the mounting post) is fully tightened. 
(To tighten the screw, reverse the instructions in step 8, 
above.) Also, make certain that you will not drill through 
any  wiring  or  electrical  components  underneath  the 
carpeting,  or  damage  any  components  on  the  other

continued on next page

continued from preceding page

(Figure 4) attaching the cylinder to the adjustable arm 
(Figure 4). Slide the air cylinder (Figure 4) up the ad-
justable arm until the anchor plate is over the point you 
have chosen. Replace the two bolts and nylon nuts.

 

 

Note:  if  BrakeMaster  is  switched  between  towed 

vehicles,  it  may  be  necessary  to  lengthen  or  shorten 
the reach of the air cylinder, as described above.
 

  Note: if the vehicle is equipped with an automatic 

pedal positioning system, adjust the brake pedal to its 
farthest extension (as close as possible to the driver’s 
seat) before positioning the air cylinder and the mount-
ing post. This will eliminate the possibility of positioning 
the anchor plate too close to the brake pedal.

 

8.

  Next, if necessary, move the air cylinder to the left 

or the right, until the mounting post (Figure 4) is directly 
in line with the brake pedal. 

   

the air cylinder must be mounted directly in line 

with  the  brake  pedal.  if  it  is  mounted  at  an  angle 
to  the  brake  pedal  (to  one  side  or  the  other),  the 
air cylinder may jam in the extended position when 
brakemaster  is  activated,  which  will  cause  severe 
brake system damage, as well as other consequen-
tial, non-warranty damage.

 

 

Note: the anchor plate can be rotated clockwise or 

counterclockwise, if necessary, to clear any obstructions 
—  to  rotate  the  anchor  plate,  remove  the  air  cylinder 
and lock the plate in a vise. Use a half-inch open-end 
wrench to loosen the mounting post, while holding the 
retaining screw (at the bottom of the plate) with an Allen 
wrench. Do not turn the retaining screw with the Allen 
wrench, as you may damage the wrench or the screw. 
When  the  mounting  post  is  loose,  rotate  the  anchor 
plate. Then, tighten the mounting post. 

 

9.

  Before  attaching  the  anchor  plate,  verify  that  the
