ABSTRACT:
The invention provides an integral brake disk comprised of two brake disks each having a disk thickness of one-half the design required disk thickness and these two disks are clamped together in planar face-to-face orientation by fasteners to form the integral brake disk. The integral brake disk has an inboard-facing brake wear surface provided by a wear surface of a first of the combined brake disks and an outboard-facing brake wear surface provided by the second of the combined brake disks. The integral brake disk is put into braking service for a first period after which refurbishment is required. The integral brake disk is refurbished by declamping the two disks and grinding the worn wear surfaces to planar specification. The two disks are recombined at the ground planar surfaces and reclamped to form a new integral brake disk. The new integral brake disk has an inboard-facing brake wear surface provided by the second of the two disks and an outboard-facing brake wear surface provided by the first of the recombined disks. The integral brake disk may now be used for an additional period of braking service.
