Image Number 2 for United States Patent #7383926.
A disc brake which is particularly designed for arcuate travel of less than 360 degrees has sector shaped segments, i.e. segments which are not complete circles and which are interleaved into a disc pack of multiple layers, wherein some layers of the disc pack each consist of a single disc segment which is less than a complete circle. Some segments are rotatable about an axis and others are stationary and have friction brake material carried on them at a position remote from the axis of rotation.
