The Brake Expander with OEM number 1-47601087-0 (without hyphen 1476010870) is a verified direct-fit replacement for ISUZU CXZ51K and CYZ51K series heavy trucks equipped with the 6WF1 diesel engine. This expander serves as the core actuator of the air drum brake system, converting force from the brake chamber into expansion force on the brake shoes via a wedge mechanism, pushing the shoes against the brake drum to achieve vehicle braking.
