Why Choose the Shimano J05A-RF Disc Brake Pad?

The Shimano J05A-RF is the premium resin replacement pad for mid to high-end Shimano MTB hydraulic disc calipers, spanning XTR M9000, Deore XT M8000 and M8100, SLX M7000 and M7100, and Deore M6000 and M6100. Built on Shimano's 5th-generation resin friction material, the J05A-RF delivers quieter operation and improved modulation over older resin compounds, with 50% better wear resistance than the J03A and 110% better than the J02A. The integrated alloy radiator fin actively pulls heat away from the pad during sustained braking, maintaining consistent feel and reducing fade on technical descents where brake heat builds quickly.

The narrow type J pad shape fits 2-piston Shimano hydraulic MTB calipers and uses an alloy back plate for rigid, rattle-free pad support. Compatibility spans BR-M9000, BR-M9020, BR-M987, BR-M985, BR-M8100, BR-M8000, BR-M785, BR-M7100, BR-M7000, BR-M675, BR-M666, BR-M6100, BR-M6000, BR-M615, BR-RS785, BR-R785, BR-S700, and BR-U8000. Each package includes one pair of pads with spring. The J05A-RF is the right choice for trail and enduro riders who want resin braking feel with meaningfully better longevity and heat management than previous Shimano resin generations.
