A practical choice for riders replacing resin pads in a compatible Shimano four-piston mountain-bike or e-bike brake caliper who value modulation, reduced noise and improved pad life.
The BP-D03S-RX is a replacement resin disc brake pad for selected Shimano four-piston brake calipers. Its 3rd-generation resin lining is designed to deliver less noise and better modulation, giving you a more controlled lever feel on everyday rides and technical descents.
A stainless-steel back plate supports consistent construction, while the narrow D pad shape matches the specified Shimano calipers. This version is supplied without a radiator fin, making it a straightforward choice when your existing setup calls for a finless pad.
Before ordering, check your caliper model carefully. Compatibility includes BR-M6120, BR-M6220, BR-M7120, BR-M8120, BR-M820, BR-MT420, BR-MT520 and BR-U8020, plus BR-M8020, BR-M810 and BR-M640. A spring and split pin are supplied.
After installation, bed in the new pads correctly before demanding maximum braking performance. Replace worn pads promptly and keep the friction surfaces free from oil or other contamination.
