Abstract
Abstract An anti-rotation device for a lever operated brake actuator for an all terrain vehicle of the type having brake cables connected to the brakes for the wheels of the vehicle. The actuator including a housing mounted on the vehicle, a lever arm pivotally mounted in the housing and being operatively connected to the brake cables, a sheath enclosing each of the brake cables and having one end secured to the vehicle in close proximity to the brakes. The anti-rotation device including an adjusting member connected to the other end of the sheath and mounted for axial movement in the housing, the adjusting member also including a threaded bore; a cable adjusting member mounted for rotary motion in the housing and having a threaded stud matingly engaging the threaded bore in the adjusting member, a thumb wheel mounted on the threaded stud for adjusting the length of the sheath and a cover mounted on the housing and including a number of ribs for preventing rotation of the thumb wheel.
