Abstract: A brake operating device (30) is configured such that actuation of the brake lever (34) around the lever pivot (36) displaces the cable (38) in a direction transverse to the cable length toward the lever pivot (36), as the user is actuating the brake lever (34). This provides at least a 33% increase in mechanical advantage over the actuation range of the brake lever (34).

Abstract: A positioner member having a spherically curved wall with an opening through it, a receiver having a surface complementary to the curved wall to nestably interfit with it, a releasable locking member disposed behind the curved wall, and an elongated connector member extending from the receiver through the opening in the curved wall and into engagement with the locking member to permit tightening and loosening of the positioner and receiver, whereby they may be moved relative to one another in a three-dimensionally orbital manner when the connector and locking element are loosened but immovably clamped when these two elements are tightened. The positioner member is attachable to a desired external support such as an automobile dashboard, and the receiver is attachable to a brake controller or other such device. The receiver may be integral with the brake controller, formed in or attached to a side thereof.
