It converts the linear push of the brake chamber into rotational force, spreading the brake shoes against the drum to slow the vehicle. You replace this when the cam head or splines are worn, the shaft is bent, or after bearing/seal failures that damage the shaft. Proper camshaft condition is critical for even brake application and to prevent uneven shoe wear.
