Abstract: A bimetallic brake rotor includes a rotor body composed of a first material and a pair of cheek inserts serving as the rotor cheeks, being composed of a second material less dense than the first material. Each of the cheek inserts has a first sequence of slots and teeth, and a disc component of the rotor body has a second sequence of slots and teeth on each side thereof which mesh with the first sequence such that a radial edge interface is provided at each adjoining tooth and slot which transfers braking heat and mechanical loading from the cheek inserts to the rotor body.

Abstract: A retainer assembly comprises a pin including a head and a flange defining a groove therebetween for engaging a first panel. A grommet includes a collar encompassing the pin and flexible arms extending from a hinge point at the collar. The assembly is initially in a shipped position wherein the flexible arms extend along the pin and are maintained in a pocket between ribs of the pin. The pin is inserted through a second panel until the collar engages the second panel. The grommet bends at the hinge points allowing the flexible arms to slide out of the pocket and adjustable engage the pin and the second panel until the second panel is maintained in position by the flexible arms, collar, and flange. Upon removing the assembly from the panels, the grommet adjusts back to the shipped position and the assembly is ready for reuse.
