Engineered for heavy - duty trucks, Jinnge's best brake discs combine strength and durability. Made from FC350 gray cast iron, these discs withstand the high compressive forces of truck braking systems. Their thick construction (up to 35mm) and robust vane structures prevent deformation under repeated heavy braking. The discs feature a special heat - resistant coating on the friction surface to reduce wear and extend service life. They are ideal for long - haul trucks, dump trucks, and other commercial vehicles.
