1. Depressurize the air system - Drain all air pressure from the brake system
2. Safely lift and support the vehicle - remove the wheel and brake drum
3. Remove the old brake expander - disconnect air lines (mark positions) and unbolt the expander from the backing plate
4. Clean the backing plate mounting surface - remove old sealant and debris
5. Compare new expander with old - verify mounting bolt pattern, air port sizes, and piston travel
6. Install new expander - apply thread sealant to air fittings, bolt to backing plate, torque to specifiion
7. Reconnect air lines to correct ports - use new sealing washers or O-rings
8. Reinstall brake drum and wheel - adjust brake shoes if necessary
9. Re-pressurize the air system - check for leaks using soapy water
10. Test brake operation - apply and release brakes to verify proper actuation and return
11. Road test - check for smooth, even braking and no air leaks
