A brake disk for a disk brake, in particular, for motor cycles or bicycles, includes a brake band of a first material which has a high heat resistance and an inner part () of a second material which has a lower density than the first material. The brake band and the inner part () each have a plurality of extensions, which in each case are arranged in pairs bordering one another. A plurality of connecting elements connect the brake band () to the inner part () by being received in recesses () formed in the extensions. Thus, a divided brake disk has little deformation or wear in the region of the connection between the brake band and the inner part in combination with a low weight. Specifically, the recess () is formed in such a way that the connecting line () between the ends of the recess () is at an angle &#x3b1; of from 15 to 85&#xb0; to the tangential direction ().

Brake disk

A brake caliper for a disk brake, in particular for motorcycles and/or bicycles, includes a housing () in which a disk space () for receiving a brake disk and a brake cylinder () for receiving a brake piston () are formed. The brake cylinder () is connected to the disk space () and has, on its side opposite to the disk space (), an assembly opening () through which the brake piston () can be inserted into the brake cylinder (). A closure element () closes the assembly opening () after the insertion of the brake piston () into the brake cylinder (). A securing element () secures the closure element () in the assembly opening () against forces in the direction of the main axis of the brake cylinder ().
