Abstract
A brake ( ) for a hydraulic vehicle brake system has a housing ( ) with a bore ( ) which is formed therein and in which a brake piston ( ) is received in a sealingly and slideably displaceable manner. The brake piston ( ) is adapted to press a brake lining ( ) against a brake disk ( ) by way of hydraulic pressure. For sealing, the brake piston ( ) is sealed off relative to the bore ( ) by a sealing ring ( ) made of elastic material. In order to optimize the adhesive and sliding properties between the sealing ring ( ) and brake piston ( ), the sealing ring ( ) and/or at least that outer surface of the brake piston ( ) which cooperates with the sealing ring ( ) is coated with a lacquer which contains an organic binder and a solid lubricant.
