Shimano's XT/XTR Wintertime Metallic Pad
Cooler brakes stop more reliably, and Shimano's XT/XTR J04C Metallic Disc Brake Pads use metallic construction to provide confident all-around stopping power in the wet, gritty, and dirty conditions associated with shoulder season mountain biking.
On their own, metallics are reliably effective in wet or dry conditions, lasting much longer than their resin counterparts. The pads are made with aluminum cooling fins that radiate heat outward, improving the pads' ability to stay cool under hard braking.
If you're running Shimano XT or XTR hydraulic disc brakes on your bike and want a go-to wintertime pad for wet, muddy and gritty conditions. This is the one.

super helpful to have a list of the compatible brake systemsas I had never changed the brake pads or sourced them myself (both super easy).
*Note: Compatible with the following brakes: XTR BR-M9000, BR-M9020, BR-M985, XT BR-M8000, BR-M785, SLX BR-M666, Alfine BR-S700 and BR-R785, BR-RS785.*
Braking performance it great, havent ridden with them in the rain yet, but they're much quieter than the non-OE pads they replaced. Ended up getting two sets. I like the fins, too.
This is my second set of Shimano's metal disc pads, which have excellent stopping power for the price. They installed in minutes on my Cannondale CAAD 12 disc, putting the stopping power back in my Shimano hydraulic brakes. As noted in the title of the review, they tend to be louder than resin pads. If you're not bothered by the noise (I'm not), and want to stop efficiently, go with these. I reduced my rating from 5 to 4 stars simply because for some they might be too noisy for some riders. I definitely recommend.
I was nervous about changing my hydraulic disc pads myself, but actually its really easy. Check out a Park Tool video on changing these pads-it will take you about 10 minutes.
These pads work well and are easy to install. There was no need for a break-in period and they are quiet. They were the same as the original brake pads that came on the bike and lasted about 7800 miles.
I prefer the metal compound pads for most situations. They have faster initial bite and overall better stopping performance in wet and dry conditions. They also last longer than the organic compound pads. The only situation where I dont like them is riding in a race peloton. Shimanos Servo Wave Technology causes the braking to be a little touchy with these pads and its harder to make subtle changes in speed.
