Ladies and Gentlemen,

My Tenere is coming up to the 2 year service interval and I'm going to do it myself. Looking at the maintenance schedule 2 items listed have thrown up some questions. The first relates to the rear suspension linkages, which according to the handbook want lubricating with lithium soap based grease. Is Castrol LM or Shell Retinax A grease suitable for this? And do you have to dismantle the suspension to lubricate it properly, the repair manual doesn't offer any guidance really. The second point concerns the brake master cylinders. The manual says to replace the internal components. I've never heard of doing this ever, let alone every two years - what do you think, if you've had a dealer do the 2 year service for you have they replaced these?

Any guidance greatly appreciated.
