Filling and bleeding a Magura hydraulic clutch does not need to be a routine chore and should only need to be done when air infiltration within the system is suspected. Magura uses mineral oil, which does not absorb moisture from the environment, to lubricate the whole system.

Note: Magura hydraulic systems use ONLY mineral oil. Do not introduce DOT brake fluid of any kind into a hydraulic system designed to use mineral oil as this will cause corrosion to the internal seals and system failure may result. The only time anyone should ever need to replace the hydraulic fluid in a Magura system is following a hydraulic line exchange, a system upgrade, a crash which has damaged the system components or in a situation where a lack of fluid within the system has been diagnosed by poor lever feel.

If you do need to bleed your Magura hydraulic system, their custom made kit does indeed make that chore easier.
