Advantages of Two Piece Rotors

In most applications, a two-piece “floating” disc assembly is used, with a cast-iron disc specially mounted to a billet aluminum hat. The advantage of this type of construction is reduced weight. By making the center-section of the disc out of aluminum, a great deal of weight can be saved in a key location, as it is both unsprung and rotating. The greatest advantage, however, lies in the float itself. The brake discs must cope with extreme temperature levels. In the case of a non-floating disc, thermal stresses develop which lead to warping of the disc and cupping of the braking surface. With the full floating system, the disc is free to grow relative to the bell, and can remain straight and true.

The net result is a braking system, developed specifically for each vehicle application by Pro-Stop Performance’s immense technical resources, that insures high quality as well as high performance.
