Shimano N03A-RF Disc Brake Pad and Spring - Resin | Finned | One Pair
What Brake Systems Use the Shimano N03A-RF Disc Brake Pad?
The N03A-RF is a resin compound disc brake pad with alloy cooling fins for Shimano's 4-piston hydraulic MTB calipers that use the N-series pad shape, specifically the BR-M9120 XTR 4-piston, BR-M8120 Deore XT 4-piston, and BR-M7120 SLX 4-piston. These are the current-generation 4-piston calipers designed for the most demanding trail and enduro riding, and the N03A-RF is Shimano's designated resin pad for these systems. The resin compound provides smooth, progressive modulation with low noise in dry and wet conditions, which remains the preferred brake feel for riders who want precise control over braking force rather than maximum bite. This is a significant step up in wear life from the previous N01A generation, with approximately 50 percent more pad material before replacement is needed.
The alloy radiator cooling fins on the RF version act as a heat sink on the pad backing plate, drawing thermal energy away from the pad surface and caliper pistons during sustained braking. This is particularly relevant on 4-piston systems which generate more clamping force and consequently more heat compared to 2-piston alternatives. The fins delay the onset of fade on longer descents and protect lever feel over time by reducing heat transfer to the hydraulic fluid. The N03A-RF is also eBike rated, confirming it handles the higher thermal and mechanical loads generated by electrically assisted braking situations. Each package contains one pair of pads with springs. For riders running any of the compatible Shimano 4-piston calipers who prefer resin compound, the N03A-RF is the correct finned pad specification.
