Abstract
A method of monitoring the service life of a ceramic brake disk, in which the load of the brake disk is computed by way of the actual sensed braking and driving dynamic characteristics and is compared with a definable reference value for the service life.
Claims4
A method of monitoring the service life of a ceramic brake disk in a motor vehicle, comprising the steps of:
- sensing the driving speed, the brake pressure and the braking period for individual braking operation;
- adding-up of the brake pressure of selected ones of said individual braking operations (E-BR) and thus forming a sum (Σ, ΣG);
- comparing said sum with a predetermined reference value (RW-X);
- and
- providing at least one of a visual and acoustic indication when said sum exceeds said predetermined reference value.
