A strong choice for MTB riders replacing pads in a compatible Shimano four-piston caliper who prioritise quiet operation, smooth modulation and dependable heat management.
The Shimano BP-N03A-RF is a resin disc brake pad for Shimano four-piston calipers, using a narrow Type N pad shape and an alloy back plate. It is compatible with BR-M9120, BR-M8120, BR-M7120 and BR-U8020 calipers, making it a straightforward replacement for a range of Shimano XTR, Deore XT, SLX and CUES braking systems.
Choose the resin compound for quiet, predictable braking and a controlled lever feel. Compared with harder-wearing metallic options, resin pads are designed to offer smooth operation with excellent modulation, making it easier to fine-tune braking on technical trails and everyday rides.
The integrated radiator fin helps dissipate heat from the pad area. That cooling support helps extend pad life and reduce fade, while keeping braking performance more consistent during sustained or repeated use. Check your existing caliper model before ordering to confirm the fit.
