Instructions

1.

  

Locate the mounting post (Fig.1) that came with your 

BrakeMaster. If needed, order part number 450596. Now, 

secure the post to the center of the seat adapter using the 

included 3/8" x ¾" bolt and 3/8" lock washer. If the hole is 

countersunk, use the Allen head bolt and lock washer includ-

ed with this kit.

2.

  

Push the driver's seat back as far as it will go, and re-

move the two front seat track covers (Fig.2). They will not be 

replaced.

3. 

Remove the two 13mm (head) seat track bolts attaching 

the front seat track to the floor pan. Place the shorter pipe 

spacer over the inside mount, and the longer one over the 

outside mount (Fig.3). 

4. 

Place the seat adapter over the pipe spacers you in-

stalled in the previous step. 

Note:

 make certain to position 

the adapter so that the mounting post is directly in line to the 

brake pedal. The BrakeMaster air cylinder may jam or func-

tion incorrectly if the mounting post is not directly in line with 

the brake pedal.
