Clarks 839C Disc Pads

No, these pads are specifically designed for mechanical disc brake systems, such as the Avid BB5, Box Three, and Promax DSK-300. They will not fit hydraulic calipers.

Organic pads are generally quieter and offer a more progressive, predictable feel at the lever, which is ideal for everyday riding. While metallic pads often last longer in wet or muddy conditions, organic pads provide a smoother, less aggressive bite that many riders prefer for general use.

Yes, you should always bed-in new brake pads to ensure optimal performance. After installation, perform several controlled stops from a moderate speed on a safe, flat surface to transfer a thin layer of pad material onto the rotor, which helps prevent noise and improves stopping power.

While these organic pads perform well in most general riding conditions, they may wear down faster than metallic pads if you frequently ride in heavy mud or grit. If your local trails are consistently wet and abrasive, you might find yourself replacing them more often.

You should inspect your pads if you notice a significant decrease in stopping power, hear a metal-on-metal grinding noise, or if the friction material thickness is less than 1mm. It is best to replace them before they wear down completely to avoid damaging your rotors.
