Abstract: A device for detecting the clamping force of a brake caliper of a vehicle braking system comprises a force sensor, a force transmitting element suitable to transmit a clamping force exerted by the brake caliper to the sensor, and a limit stop element. The transmitting element is movable when subjected to a clamping force exerted by the brake caliper. The force sensor is configured to measure a clamping force up to a sensor force threshold value which is lower than the maximum clamping force exertable by the caliper. The mechanical limit stop element is configured to be engaged by the force transmitting element when the clamping force exceeds the sensor force threshold value.
