Whilst on the subject of hydraulic systems, be it brake or clutch, it's worth mentioning how important to flush out and replace the hydraulic fluid at regular intervals, preferably as specified in the service schedule as every 2 years. This is something that is very often ignored and never looked at until a problem occurs and I suspect a lot of dealers don't do this when servicing vehicles. The reason that it should be done is that water builds up inside the system that apart from reducing it's efficiency, can also cause corrosion of metal components (mainly the steel pistons in used bike assemblies but also in steel cylinders used in cars as well) that will be much more costly to repair. So a little time spent doing this job every couple of years reduces the risk of potential clutch or brake problems and the considerable expense of new components. Have a go and you'll be surprised at the colour of the old fluid and sometimes what gunge comes out!
