9600 Periodic Maintenance Procedure 

 

00-880606-02 

Page 17 

Newer Cross-Arm Brake Systems: 

5.  If brake tension requires adjustment, turn the handle approx. 5 - 10 degrees to the right so as to push 

the brake shoe down onto the Cross-Arm and to move the brake mount up for adequate clearance 
between the brake and Cross-Arm when the brake is unlocked.  The brake shoe should be barely 
touching the Cross-Arm. 

6.  Tighten the 4 torx screws to secure the brake mount to the Cross-Arm housing. 

7.  With the handle in the slightly angled position, use Loctite 222 and tighten the two bottom set 

screws. 

8.  Turn the handle approx. 90 degrees to the right to lock the Cross-Arm, then grasp the Cross-Arm 

handle and attempt to move the Cross-Arm in and out to ensure it’s locked in place.  If the Cross-
Arm can still move, make adjustments again with the brake shoe and set screws.
