Disk brake for motor vehicle, has brake disk comprising two circumferential patterns which correspond to radially lateral-edge regions of friction surface, where brake pad is pressable on brake disk

摘要

The brake has a brake pad that is pressable on a brake disk (1) by a friction surface (5). The friction surface has two regions with different friction values, where the regions are arranged in form of concentric ring segments. A center point of the concentric ring segments lies on a brake disk axis. The friction surface has radially edge-lateral regions (2', 3') that are provided as resets to provide a lower frictional force. The brake disk has two circumferential patterns (2, 3) that correspond to the radially lateral-edge regions.
