摘要

A method for checking the characteristic curve of a force measuring spring in a cable pull system, in particular in a brake cable pull system of motor vehicles, whereby as a function of a deformation δx (f) of the force measuring spring of the cable pull system a restoring force f (δx) occurs, and when reaching a predetermined reference force f₁ and a deviation of the actual deformation value δx (f₁) deformation of a reference value δx₁ an error is signaled, characterized in that, when a second predetermined reference force f₂ F₁, the reference force f₂ smaller than the force of at maximum voltage of the force measuring spring up to the stop of the cable pull system is, in the case of a branching off of the actual deformation value δx (f₂) deformation of a reference value δx₂ a change in the spring characteristic is signaled.
