Multi-disc brakes

摘要

A multi-disc brake suitable for an aircraft has a stack of rotor and stator discs in which the discs of a set at one end of the stack each have a greater allowance for wear than the discs of a set at the other end of the stack whereby the group of discs are removed together from one end of the stack as a fully worn group at a brake servicing operation. An unworn group of discs is added to the other end of the stack.
