The slack adjuster is mounted on an inboard end of a camshaft of the drum brake system. The inboard sealing assembly sealingly engages with an inboard side of the slack adjuster. The sensor arrangement measures rotation of the camshaft and is at least partially disposed within the inboard sealing assembly to protect the sensor arrangement from impact damage, water, chemicals, and debris.
