Corrosion protective lacquer for braking surfaces of brake disks and/or brake drums, corrosion protective coating produced therefrom, and a method for removing the corrosion protective coating

Abstract

A corrosion protective lacquer is for producing a corrosion protective coating, and a method is for removing the corrosion protective coating. For a more favorable removal, while maintaining simultaneous corrosion protection, the corrosion protective lacquer, and thus also the corrosion protective coating produced from it, includes protective substances that react with oxygen. The corrosion protective coating is abraded by the abrasive effect of the brake linings during braking, the protective substances of the corrosion protective coating being rubbed into the braking surface.

         15 . The corrosion protective coating according to  claim 11 , wherein the protective substance in the corrosion protective coating has a proportion of at least 50% by volume.  
     
     
         16 . The corrosion protective coating according to  claim 11 , wherein the protective substance in the corrosion protective coating has a proportion of at least 70% by volume.
