Shimano L04C Disc Brake Pads

The Shimano L04C Metal are sintered brake pads with cooling fins, suited for Shimano road bike disc brakes. The compound of sintered brake pads is made of resin mixed with metal particles placed on a backplate with cooling fins. 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. This property is enhanced due to the cooling fins on the backplate, which reduces heat generation to a minimum. In addition, sintered brake pads are very wear-resistant and made for braking in muddy terrain. These brake pads will ensure proper stopping power in all circumstances. 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. In addition, these brakes provide good stopping power during long mountain rides. 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.
