Shimano J05A Resin Brake Pad With Fin

The J05A-RF (also called BP-J05A-RF) is fully compatible with BR-M9000, BR-M9020, BR-M987, BR-M985, and all other two-piston Shimano calipers previously using J03A

Shimano rolled out J05A-RF in late 2022, touting 50% better wear than J03A and 110% more than J02A, thanks to 5th-generation resin tech and enhanced heat dissipation
