Magura Royal Blood Hydraulic Oil 100ml It cannot be said often enough. Bleeding of a Magura brake is not a routine maintenance task, because Magura Royal Blood mineral oil neither absorbs water nor does it age. Replacement is only required after a crash or when a hose was torn. It also lubricates the whole brake system and neither irritates human skin nor strips the paintjob of your frame - in a nutshell: nicer stuff to deal with!! Never use DOT brake fluid on Magura brakes as this would destroy your brake
