Kool - Stop disc pads are crafted from organic materials, blended and bound with resin. These pads contain small amounts of metal to enhance the braking formula. Although metal is a mined material, the pads are predominantly organic, and can also be referred to as semi - metallic. During testing, Hayes found that these disc pads are rotor - friendly and offer high - performance braking throughout their lifespan. SPECIFICATIONS: Compatible with MX - 2 (2004), MX - 3 (mech.), SOLE, and Promax DSK - 810. Weight: approximately 13 gr/pair.

Using these Kool Stop Hayes Mx2 Ksd220 brake disc pads is easy. Just install them on your compatible bike's braking system as you would with regular pads. When using, apply the brakes smoothly and steadily for best results. For maintenance, check the pads regularly for wear. If they look very thin or worn out, it's time to replace them. Also, keep the pads clean by gently wiping them with a soft cloth to remove any dirt or debris. Avoid getting oil or grease on the pads as this can reduce their braking performance.
