Диск тормозной передний ABT LACETTI 978F

Structurally, brake discs are divided into three types: Solid. The brake disc, in which the hub part and the working cloth are made of solid blank. This design does not provide additional cooling. Ventilated. Two plates connected by radial ribs forming channels for additional ventilation of the disk. Thanks to these channels, air moves from the hub to the outer edges of the disk, accelerating the cooling of the system. The use of an air layer allows to reduce the temperature of the working area of the friction pair by 30% or more Composite. A prefabricated structure consisting, as a rule, of an aluminum hub part and a cast-iron ring, which is a support surface in a friction pair. This technology lightens the weight of the disc, increases resistance to thermal deformation, and minimizes the transfer of accumulated heat to the hub. The required type of brake disc is determined by the type of brake system of a particular car model.
