Description:
Cat brake discs, such as 123-4398, are designed to work with brake pads in braking systems, providing critical friction to slow, stop or hold a machine stationary. Cat drive train components must endure incredible torque, high impact loads, and frequent direction and gear changes. Cat designs and manufactures its transmissions and final drive components with these demands in mind. The result is a drive train that lasts longer and works harder over the life of the machine.
