Using these Shimano brake pads is straightforward. First, make sure your bike's brake system is compatible with these pads. If it's one of the listed models and series, you're good to go. Remove the old pads and carefully install the new ones in their place. When riding, expect improved braking power due to the high - durability resin. As for maintenance, check the pads regularly for wear. If they start to get thin, it's time to replace them. Avoid getting the pads wet with oil or grease as this can reduce their braking effectiveness. Store them in a dry place when not in use to keep them in good condition.
