A motor vehicle brake comprises in combination a drum brake and a disc brake. The disc brake has a brake caliper which is pivotally mounted to turn, under the reaction of the disc brake, into a position to apply the drum brake. It is thus possible to distribute the braking reaction and to reduce the magnitude of the brake-applying forces, thereby also decreasing the braking surface area requirement and increasing the life of the friction linings.
