Using these BMX brake pads is easy. First, make sure your bike is on a stable surface. Then, use the knurl - lock washer system to install the brake pads securely on your bike's brakes. When riding, just squeeze the brake levers as you normally would to stop. In wet conditions, don't worry as the pads are designed to keep their stopping power. As for maintenance, regularly check the pads for wear. If they're worn out, it's time to replace them. Also, keep the pads clean to ensure they work at their best. And always follow basic bike safety rules when riding.
