Abstract

Perfection in drum brakes with internal shoes, of the type comprising a brake shoe support, a first and a second brake shoes mounted on the shoe support, and a first and a second brake shoe expander devices, driven by pressurized fluid, each mounted between a pair of adjacent ends of the brake shoes, the first shoe expander device having a thrust element acting on the adjacent end of the first brake shoe and having the second device shoe expander a pushing element acting on the adjacent end of the second brake shoe, enabling a fixed stop for the end of each brake shoe opposite the end on which one of the thrust elements acts, characterized in that a lever pivots on the second brake shoe adjacent to the center of the shoe and has arms extending to opposite ends of the shoe of in this case, expander means of mechanical operation acting between an arm of the lever and the end of the first brake shoe on which the thrust element of the first pressurized fluid shoe expander device acts, enabling a stop for the other one, is enabled. Arm of the lever in the support gives the brake shoe in order to limit the movement towards the inside of the arm of the lever, and enabling stops of mutual cooperation in the second shoe and the lever to limit the movement towards the interior, with relation to the lever, of the end of the second shoe adjacent the second expander device of the pressurized fluid shoe.
