ABSTRACT:
In a key activated vehicle drum brake telescopically displaceable variable force transmitting elements have been arranged between the key and the brake shoes of the brake. In order to provide a design counteracting axial displacement of the brake shoes the variable force transmitting elements and the brake shoes have interengaging contact surfaces, the curve radius of the ends of the elements in a plane containing the drum axis are more than twice the curve radius of the same surfaces in planes perpendicular thereto.
