    Abstract: A disc assembly for a vehicle disc brake has a rotor with a pair of opposite faces from which are mounted annular braking discs. Each disc is mounted for limited radial movement on a carrier device by fasteners located outside the braking area of the disc; and the disc and the carrier device have complementary radial abutment faces, the carrier device being mounted on the rotor by connectors. The brake torque is transmitted from the discs to the carrier device by the abutment faces and then to the rotor by the connectors. This provides a simple construction which reduces stress on the discs and permits and guides radial expansion of the discs during braking.
