Drum brake device for a road vehicle, in particular a motor car, of the type generating a braking torque between a drum and a backing plate in rotational movement with respect to each other, by absorption of energy under the effect of friction between: on the one hand, a braking surface forming a cylinder of revolution and which is borne by an inner surface of said drum, and on the other hand, brake linings (123, 133) borne by a first and a second shoe (12, 13) arranged inside said cylinder and transmitting the braking torque to said backing plate at least by an element called an anchor forming an abutment for the shoes. said friction being able to be obtained by moving apart at least one of said shoes outwards, under the effect of at least one first actuator, thus ensuring a braking function in a first mode of operation which brings the device into a first braking position, said device being characterized in that it comprises an element called a spacer element, which is mobile with respect to the backing plate and is arranged in order to hold apart from each other two ends of said shoes that are opposite each other, called mobile ends (121, 131), in that it also comprises at least one second actuator, arranged in order to be able to move apart from each other the ends of said shoes situated on the opposite side, called stop ends (122, 132), and thus press said shoes against the braking surface of the drum, thus making it possible using friction to transmit a braking or holding torque when stationary, between said drum and a first shoe, which presses via its mobile end on said spacer element, which presses on the mobile end of the second shoe, which via its stop end transmits said braking or holding torque to the backing plate, thus providing a braking function in a second mode of operation which brings the device into a second braking position. on the one hand, a braking surface forming a cylinder of revolution and which is borne by an inner surface of said drum, and on the other hand, brake linings (123, 133) borne by a first and a second shoe (12, 13) arranged inside said cylinder and transmitting the braking torque to said backing plate at least by an element called an anchor forming an abutment for the shoes. said friction being able to be obtained by moving apart at least one of said shoes outwards, under the effect of at least one first actuator, thus ensuring a braking function in a first mode of operation which brings the device into a first braking position, said device being characterized in that it comprises an element called a spacer element, which is mobile with respect to the backing plate and is arranged in order to hold apart from each other two ends of said shoes that are opposite each other, called mobile ends (121, 131), in that it also comprises at least one second actuator, arranged in order to be able to move apart from each other the ends of said shoes situated on the opposite side, called stop ends (122, 132), and thus press said shoes against the braking surface of the drum, thus making it possible using friction to transmit a braking or holding torque when stationary, between said drum and a first shoe, which presses via its mobile end on said spacer element, which presses on the mobile end of the second shoe, which via its stop end transmits said braking or holding torque to the backing plate, thus providing a braking function in a second mode of operation which brings the device into a second braking position.
