Brake disc is a metal disc what mounted on the axle or wheel, along with the rotation of the wheels. The vehicle goes to slow down or stop when the brake discs brake by brake pad. General brake disc is provided with a circular hole. Its role is reducing weight and increase the friction. Brake discs are different, which is characterized in that the wall is thin, disc and the center is formed by sand core. Different kinds of brake disc, in the disc diameter, disc thickness and two pieces of gap size differences, hub thickness and height also each are not identical.
TEDRAIL supply brake disc for railway applications such as passenger coach and locomotive which is fully content of AAR and UIC 541-3 standard.
There are two types of brake discs:
