8. Remove the four (4) black 10mm bolts mounting the brake (S1906) to the
monocoque. The brake will be supported by the two (2) tensioning bar
bolts, which should be finger-tight from the previous step.
9. Remove the Poly-V belt from the brake pulley (P1576).
10. Make sure all wires to the brake are disconnected and out of the way.
11. While holding the tensioning bar firmly, remove the tensioning bar bolts.
Warning: The brake weighs approximately 40 lbs.
12. While holding the tensioning bar with one hand, cradle the bottom of the
brake with the other hand. Pull the brake towards you, channeling the
idler pulley through the obstructions on the sides of the brake.
Installation
Installation is reversal of the removal procedure with the following exceptions:
1. Verify the Philips shipping screws have been removed from new brake.
2. Remove tension bolt and brake tensioning bar from the old brake and
install on the new brake.
3. Before installation of the belt, return brake to original position marked on
the sides of the monocoque. This action will preset the brake belt tension
to its original setting. When the brake is at its original position, tighten the
four (4) black 10mm bolts. Make sure all other bolts are tight and the
cover brace is in place before the belt is installed on the brake pulley.
4. Place the belt onto the brake pulley. Loop the belt under the idler
(P1091). Start the belt onto the back of the poly-v pulley (P1097). Move
the crank arm in a forward motion to rotate the drive pulley, thus feeding
the belt onto the drive pulley. Warning: Keep hands clear of the
underside of the belt. Failure to do so could result in serious injury,
including the loss of a finger. There will be approximately 110 lbs. of
tension on the belt. If necessary, use a blunt object to push the belt
when feeding it onto the drive pulley. Make sure the belt is in all grooves
on the pulleys and is not rubbing on the side of the brake or idler. If it is
rubbing, use a flat-head screwdriver to move the belt over on the poly-v
pulley while rotating until the belt is centered.
5. Reattach wires to the brake.
