P03A-RF Resin Pad

The Shimano P03A-RF resin brake pad fits select four-piston hydraulic disc calipers, replacing worn pads to restore braking performance. The third-generation resin compound lowers noise and improves modulation for smoother lever feel, while the built-in radiator fin pulls heat away from the pad surface during extended braking descents.

A rigid metal back plate helps transfer heat away from the friction material, supporting the radiator fin's cooling effect and reducing fade during repeated hard stops. The pad shape matches the caliper's piston layout for even contact against the rotor, supporting consistent braking feel over the life of the pad.
