Shimano, D03S-Rx Resin Pad W/O Fin, W/Spring, W/Split Pin, 1 Pair

This resin brake pad uses Shimano's third-generation lining compound to deliver quieter braking and finer modulation, with roughly 40% longer wear life than the previous D01S pad. It has a narrow "D" pad profile built without a cooling fin, mounts a stainless steel back plate, and is designed for Shimano's 4-piston disc calipers such as the BR-M8120, BR-M8020, and BR-MT520 series.
