Shimano J05A-RF Disc Brake Pad and Spring - Resin Compound, Finned Aluminum Back Plate

The Shimano J05A-RF disc brake pad is designed for mountain bikers running Shimano hydraulic disc systems who prioritize modulation and heat control on sustained descents. Resin compound construction delivers consistent feel across a wide range of conditions, from dry trail to wet roots, while the finned aluminum back plate dissipates heat more aggressively than standard pad designs. The integrated spring ensures even pad retraction and minimizes drag between braking events. J05A-RF pads are compatible with select Shimano MT series and Deore-level calipers.
