We cannot repeat it often enough. The bleeding of a MAGURA brake is NOT a routing chore, because the MAGURA Royal Blood mineral oil does not absorb water (like DOT brake fluid). 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!!

If ever filling or bleeding is necessary, e.g. after a crash, use only MAGURA Royal Blood hydraulic oil, never DOT brake fluid (that will destroy your brake!)
