An automotive disk brake assembly installed in an automobile having a wheel. The assembly includes a floating caliper supporting an inner and outer brake pad and a brake rotor having a disk, and a hat, and wherein the hat is bolted to the wheel. A hydraulic cylinder is adapted to push the inner brake pads into the disk surface, causing the floating caliper to move bringing the outer brake pad into contact with the disk. Finally, the rotor is made such that a complete 100 kilometer per hour, 0.9 gross vehicle weight braking causes the disk to expand in thickness by at least 0.15 mm and to cool to shrink in thickness, relative to its expanded thickness, by at least 0.1 mm within 60 seconds of the cessation of braking, in an ambient temperature of less than 30° C.

For controlling electromechanically actuatable brakes of servo type construction, it is necessary to detect the forces acting on the abutment of the brake shoes. The abutment is therefore formed from a massive material which deforms under load, wherein measurement devices are provided which detect this deformation. The shape of the abutment is selected in such a way that the abutment has measurement gaps, the size of which changes when the abutment is loaded. The size of the measurement gaps can be sensed by means of Hall sensors or AMR sensors, for example.

A combined drum wheel brake module comprises a brake holder which can be fixed on a motor vehicle for conjoint rotation and has a counter bearing which is equipped with two brake shoes. The brake shoes are mounted opposite one another for conjoint rotation and can be displaced radially outward in the direction of a brake rotor designed as a brake drum, and wherein, for the purpose of actuating the brakes, there are at least one transmission means and two actuating devices, which are made up as a hydraulic or electric service brake actuator and as an electric parking brake actuator. Both the service brake actuator and the electric parking brake actuator are placed fixed next to one another in a semi-circle on the brake holder.
