ANTI-LOCK SENSOR RING, DISK BRAKE BAND AND ASSEMBLY
An anti-lock sensor ring may have a flattened exciting portion having a retention mechanism projecting from a ring radial edge. The retention mechanism may have cantilever spring retention clips elastically deformable to snap on a disc brake band retention seat. The mechanism may also have a cantilever support portion disposed side by side to and spaced apart from the cantilever spring retention clips. Each of the cantilever spring retention clips may have a retention surface and the cantilever support portion with a support surface. When the anti-lock sensor ring is dismounted from a disc brake band, the plane defined by the retention surface and the plane defined by the support surface are facing each other in order to create opposing gripping elements.
