Patent ID: 7900751

Claim:
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 an once refurbished disc; combining the once refurbished disc with a twice refurbished disc by a fastening element 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 once 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 once refurbished disc by a fastening element 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, wherein each fastening element allows the combined discs to have substantially the same thickness as the brake disc having the first thickness so that any one of the combined discs can replace any one of the group of rotor discs and the group of stator discs, and each of the group of rotor discs has substantially the same thickness and each of the group of stator discs has substantially the same thickness in a braking tour.
