A device for control of wear of the brake-shoe linings consists of the first and second sensors of the wear of brake-shoe linings, first, second and third comparators. There are additionally used the third and the fourth sensors of the wear of brake-shoe linings, the fourth comparator, the setting device of maximum level of the wear of brake-shoe linings, logic element AND, signal amplifier, encoder and digital signal panel. Outputs of first, second, third and fourth sensors of the wear of the brake-shoe linings are connected to the second inputs of first, second, third and fourth comparators respectively, first inputs of which are connected with the output of the setting device of maximum level of wear of the brake-shoe linings. Outputs of first, second, third and fourth comparators are connected to first, second, third and fourth inputs of logic element AND and to first, second, third and fourth inputs of encoder respectively, output digital bus of which is connected to the input digital bus of digital signal panel, the output of logic element AND is connected with the input of signal amplifier, output of which is connected with the warning circuit.
