Using these brake pads is really simple. First, locate the pin on the cartridge pad holder. Pull it out gently. Then, slide out the old brake pad. Next, choose a new pad insert from the vibrant options available and slide it into the holder. That's it! When riding, these pads will give you reliable stopping power. As for maintenance, regularly check the pads for wear. If they look thin or worn out, it's time to replace them. Also, keep the cartridge pad holders clean to ensure smooth pad replacements. And remember, these pads are designed for linear - pull brakes, so make sure your bike has the right brake type before using them.
