Shimano K04S Disc Brake Pads

The Shimano K04S Metal models are hard, sintered, brake pads that are suitable for Shimano road bike disc brakes. In the case of sintered brake pads, the compound consists of resin that is mixed with metal particles. These brake pads are also very resistant to the high temperatures that can occur, especially during long descents. The disadvantage is that these brake pads do not engage as fast as organic or semi-metallic brake pads and make more noise during braking.

These brake pads are therefore very suitable if you cycle in very muddy conditions and have to brake a lot. These brake pads are also very suitable if you are going to cycle in the high mountains with both the road bike and the mountain bike. During long descents, these metalic brake pads do not fade and they maintain their braking power. When fading, there is an oil-like layer on the brake pad. This often happens when you cycle with organic brake pads. Metallic brake pads don't have this problem, which makes them the most suitable brake pad for long rides in the mountains!

Not suitable for all rotors
These hard brake pads are not suitable for all rotors. These pads can only be used on ground brake discs, as they consist of harder material. Pressed soft rotors are only suitable for soft organic brake pads. These will wear out quickly due to harder brake pads.
