Electro Thrust (Model ET) Shoe Brakes
Self Adjust Mechanism (Optional)
 
Options
 

 
The self adjust mechanism is designed to provide automatic compensation for linear wear. When a brake is utilized, normal linear wear occurs. With the self-adjust feature, a clutch mechanism maintains the proper actuator stroke by adjusting "in" the tie rod. This also maintains the brake at it's proper operating torque.
 
For brakes with the self-adjust option, adjustments are made as follows:
  • Remove shoulder bolt 1.
  • Rotate clutch hub 2, to adjust brake, as required.
  • Re-install shoulder bolt 1.
    Note: For specific procedures see installation section.
Maintenance time is reduced as a direct result of employing the self adjust feature.
