Question I have is can I put better resin brake pads in my Shimano BR-M446 rear and front calipers. I understand the factory pads are B01S but I only got 450km out of them (a lot of downhill). Rotors are Shimano SM-RT54 and have 'resin only' printed on them. I'm systematically upgrading my bike to XT gear but brakes are still ex factory. Still relatively new to bike maintenance. Thanks.
