Method for recognition of and/or compensation for a leakage within a hydraulic anti-lock braking and/or anti-spin regulation system

A method and an apparatus for recognition of and/or compensation for a leakage within a hydraulic system, in particular within a hydraulic anti-lock braking and/or anti-spin regulation system are described. The method is characterized in that already available system components (20, 25, 30, 35, 70, 80, 90) are used for the recognition of and/or compensation for said leakage. The apparatus is characterized in that already available system components (20, 25, 30, 35, 70, 80, 90) are usable for the recognition of and/or compensation for said leakage.
