Abstract: A load-taking device for use in the disc pack of a multi-disc brake assembly. The load-taking device is located at one end of the pack, interposed between the pack and a cylinder for applying thrust to the pack or for resisting thrust applied to the pack. It has an annular support and a plurality of hollow bell-shaped load-taking members extending from one side of the support in circumferentially spaced relation which are rounded at the ends which contact the adjacent disc of the pack.

Abstract: An annular friction element for a multi-disc brake comprises pads of friction material alternating around the element with radial arms by which the pads are clamped relative to a ring joining the arms, the arms being of greater extent than the ring radially of the element.

Abstract: A disc brake comprising a number of interleaved rotor and stator elements and a brake actuator which is arranged to urge the rotor and stator elements into engagement in order to apply the brake. The engagement surfaces of the rotors and stators are provided with areas of carbon and non-carbon based friction material which are arranged so that the disc brake consists of a number of iron friction pairs and a number of carbon friction pairs, the iron friction pairs being located nearer to an open end of the brake structure so that the friction pairs most likely to be wet are those which perform best when wet.
