Abstract
A method and brake disc assembly to utilize worn refurbished brake material is disclosed. The method discloses the use of a brake disc for braking and the subsequent machining or refurbishment of the brake disc so that the brake disc can be used for three tours of braking to increase the utilization of the brake material.

A method to utilize a brake disc for braking wherein the brake disc is one of a group of rotor discs and a group of stator discs, the method comprising:
- using a brake disc having a first thickness for braking to provide a worn disc having a first worn thickness;
- machining the worn disc to a first machined thickness to provide a first refurbished disc;
- combining the first refurbished disc with a twice refurbished disc to provide a first combination of discs having a first combined thickness substantially the same as the first thickness;
- using the first combination of discs for braking to provide a worn first combination of discs including a worn first refurbished disc having a second worn thickness;
- machining the worn first refurbished disc to a second machined thickness to provide another twice refurbished disc;
- combining the other twice refurbished disc with another first refurbished disc to provide a second combination of discs having substantially the first thickness;
- and
- using the second combination of discs for braking to provide a worn second combination of discs.
A brake disc assembly comprising a pressure plate, a first group of rotor discs and a second group of stator discs, and a backing plate, the discs of the first group axially aligned and in interleaved relationship with the discs of the second group, the discs of a group each having approximately the same initial axial thickness, wherein a worn disc from one of the first and second groups was refurbished at an overhaul to provide a first refurbished disc and coupled together with a twice refurbished disc to provide a first combination of discs having a first combined axial thickness substantially the same as the initial axial thickness, and the first refurbished disc was again refurbished at a subsequent overhaul to provide another twice refurbished disc and coupled together with another first refurbished disc to provide a second combination of discs having a second combined axial thickness substantially the same as the initial axial thickness, whereby a disc of the first and second groups of discs is refurbished twice and utilized three times for braking.
