  1. Remove the original master cylinder and brake pedal.
  2. Thoroughly clean the crossmember area where the bracket bolts onto (repaint if necessary).
  3. Assemble the master cylinder (1) and power booster (2) into the bracket (3).
  4. Install bracket (3) onto the crossmember where the original bracket used to be.  Used the supplied bolts with the nuts on the top side.
  5. Install the lower pedal arm (5) to the bracket (3) with the supplied sleeve and bolt.
  6. Connect the pushrod (4) to the power booster (2) and lower pedal arm (5) with the supplied clevises.
  7. Install the upper pedal tube (6) into the lower pedal arm (5) with the tapered section on the bottom.
  8. Adjust and rotate the upper pedal tube so it will pass through the original hole in the floorboard.  Tighten the 3/8" bolt on the lower side of the tube to secure the pedal tube. Use Loctite on the threads.

    NOTE:  The upper pedal tube may not line up with the original hole in the floorboard.  To fix this, remove the lower pedal arm (5) and place in a vice.  Heat the arm red hot and then bend it to fit.   
     
  9. Adjust the pushrod so there is ˝ “of play on the pedal pad (do not preload the master cylinder).  There should very little clearance between the firewall and lower pedal arm when the brake pedal is released.
  10. Check for interference and binding throughout the pedal travel.
  11. Install the brake pedal pad (7) to the upper pedal tube (6).
  12. A new access hole on the floor needs to be cut out approximately 17" behind the original hole in the floor to allow access to the master cylinder.
  13. Reroute all brake lines into the new assembly, bleed the brakes, and connect manifold vacuum to power booster.
