Shimano E01S Metal Disc Brake Pads

The Shimano E01S Y8FL98010 brake pads are sintered brake pads for Shimano disc brakes. This fit however is also used by a number of other manufacturers. The compound of sintered brake pads is made of resin mixed with metal particles. This makes the compound very tough and wear-resistant. These brake pads are also very resistant to high temperatures that can be caused during long descents especially. The downside is that these brake pads react slower than organic or semi-metallic brake pads and produce more noise during braking.
This makes these brake pads very suited for cycling in muddy terrain requiring a lot of braking. That’s common in muddy rides in hilly terrain. These brake pads are also very suited for downhill, enduro and muddy cyclocross rides.

Note:
Manufacturers use different sizes & fits. Make sure if the shape of the brake pad in the image corresponds with your current brake pad. Not sure what shape you have, scroll down to the bottom of this page. There, you’ll find which brake pad is suited for which type of brake.
