The SM 2914 is a specialized carbon brush set designed for the Inrod-type alternators commonly found in the Tata Ace series. This 2-brush (1 Pair) set is engineered to provide the field excitation current necessary for the alternator to charge the battery. Given that the Tata Ace often operates in high-dust and heavy-duty "last mile" delivery conditions, these brushes are built for durability and consistent electrical contact.
