A bit of help and advice please if i may, i am refirbishing the clutch master cylinder as it has been weeping slightly. I am having difficulty removing the piston from the housing, cant see any way of removing it, i have removed the rubber seal and would have expected to see a circlip, but there isnt one, on looking in the seal kit it appears there is a knurled type fitment, any ideas as to how i can remove the cylinder from the body?
 
Hello,

see Lothar's posting in the "How to" section. You should find everything
in the illustrated article that you reach when clicking on the link.

Just knock it out from the banjo end with a thin drift/ground off screwdriver.  And then discover that you can't get hold of 15mm seal kits.  >:(  (At least you can't for the brake- maybe the clutch is a different size)
 
and while you are cleaning up the body ready for a new seal kit,with the two allen bolts and the reservoir removed, you will see two holes,one of them is fairly easy to get clean and clear because it is not so small, the other one looks like a drill has only touched it, and made a small countersink, but in the middle of it is a timny hole, and it too must be clear and clean, the only thing that I could find small enough to pick the sh17 out with was a single wire cut from a wire brush, parafin, and wash with water works well, but do dry everything with an air line.Make sure the bore is in operfect condition, it can take a small hone, but not many diy mechanics have one small enough.While you are doing it replace the O ring in the slave cylinder as well (about 20p) and the rubber dust cover if it s perished (very likely) Wolfgang has had remade them so they are available and maybe locally to you.
