Abstract: A disk brake assembly wherein the floating caliper member houses an adjustable nut in which is mounted a power screw for actuating the carrier members and their brake pads into frictional engagement with a rotatable disk. The power screw has a cam connected to it, with the cam also adjustable mounted on an actuating lever to permit selected rotation of the cam to adjust the axial position of the power screw to compensate for wear.

Abstract: A method of mechanically converting unbranched fibers into highly branched or "fibrillated" fibers which are especially suitable for reinforcing composite materials such as brake linings. Unbranched starting fibers, immersed in water, are subjected to prolonged working in an intensive mixer or chopper having a very rapidly spinning blade with sharp knife edges, until extensive fiber branching occurs. Fibrillation can be achieved by this method even though conventional fiber "refining" techniques have no significant effect on the same starting material.
