Light weight Floating Front Disc Brake Lightweight Floating Front Disc Brake Newly upgraded precision polishing processing with titanium plating on the surface,good corrosion resistance, increased strength, and more high-end. The appearance of floating discs is to solve the problem of continuous friction and temperature increase in integrated discs, which results in different temperatures and degrees of expansion between the center and edge positions of the disc due to thermal expansion and contraction,Generate internal tension, causing deformation of the disc; Generally speaking, brake failure occurs when a floating disc is made of two different materials, both inside and outside, and connected by rivets. This connection is not rigid,There is a certain amount of freedom, which reduces heat transfer on the one hand and solves internal stress problems on the other hand; So theoretically, thermal decay is related to the high-temperature resistance of materials, which is relatively stable. Floating discs do not reduce thermal decay, But if the material and design of the disc are optimized to enhance its heat dissipation ability, it will improve its anti attenuation ability!
