Hi all, I've recently replaced (with new) both the rear wheel cylinders on our 88 Vanagon - one was leaking. Also, recently I had the clutch slave cylinder replaced on my 87 Syncro. I'd like to rebuild the old cylinders and keep them as spares. The bore of all of the cylinders is very smooth and shows no signs of pitting. It seems like the leaks were like caused by old and stiff rubber seals. The seals in the rebuild kits are much more flexible and the outer sealing "skirt" is a bit larger in diameter than the old ones. I theorize that the seals, after being held inside the cylinders for 9-10 years, have assumed the diameter of the cylinders and no longer exert much force on the walls on the cylinder wall. My question is about honing the cylinders. Since they are smooth inside, does this realy need to be done? I'm a bit worried about taking a cylinder with a nice smooth bore and screwing it up with a hone. Also, any suggestions on the brand or type of hone required? Thanks, Jim Davis 87 GL Syncro 88 GL Wolfsburg
