In comparison, NAO friction materials contain approximately seventeen different stick materials, because removing asbestos does not equate to simply replacing a substitute, but requires a large batch of mixture to ensure braking performance, making it flat or Exceeds the braking effect of asbestos friction blocks.

The material of NAO brake pads has undergone several changes. Now NAO materials have effectively surpassed the performance of asbestos brake pads in many aspects, mainly in terms of anti-friction performance and noise.

Of course, the specification standard should first be determined, because only then can any new friction material formulation be tested. These specifications should include friction properties, fatigue resistance, temperature adaptability, wear resistance, and noise. The better the friction material, the better the frictional properties of the friction block under different temperatures and pressures. In other words, the performance should not change much under low temperature or high temperature conditions. The better the friction material, the less likely the brake shrinkage will occur after repeated braking, which keeps the "brake pedal feel" good. Better materials also reduce wear and reduce noise. The earlier NAO brake pads only met some of the requirements, but now they are almost completely achieved. Today's NAO brake pads have a significantly longer life than asbestos brake pads, while also extending the life of the brake drum and brake disc.
