Using these brake disc pads is easy. First, make sure your bike is on a stable surface. Open the brake caliper and carefully insert the pads into the caliper. Make sure they are properly seated. When riding, press the brake levers gently to test the braking performance. As for maintenance, regularly check the pads for wear. If the pads are worn down to about 1 - 2 millimeters, it's time to replace them. Keep the pads clean and dry to ensure good braking. Avoid getting oil or grease on the pads as it can reduce their effectiveness. Also, don't use them in extremely wet or muddy conditions for extended periods without cleaning them afterwards.
