Description of Change: A new parking brake assembly is now used. The former brake caliper could stick and the lining material could wear prematurely. The new brake assembly has added O-ring seals in order to prevent dirt contamination. This will prevent the caliper from sticking. A new lining material is used to give increased service life.

Adaptable To: The 230-3809 Brake Assembly is a direct replacement for the former 124-9462 Brake Assembly which has been cancelled. The following service repair kits are available for the 230-3809 Brake Assembly .

  • 166-9413 Cam Kit

  • 230-3810 Brake Lining Kit

  • 230-3811 Brake Caliper Kit
