A system and method for overload monitoring of vehicle brakes of electronically controlled brake systems of vehicles and of vehicle combinations. The temperatures of the wheel brakes of the vehicle or vehicle train parts of the vehicle combination are determined and compared with a preset temperature limit value, and a first warning signal is output to the driver if the temperature of the wheel brakes on one axle of the vehicle or of a vehicle train part reaches the temperature limit value. A second warning signal is output to the driver if the determined temperatures of the wheel brakes on more than one axle of the vehicle or of at least one vehicle train part or all vehicle train parts of the vehicle combination reach the temperature limit value.
