I agree with Mart. In fact I just ordered a new Master cylinder for my '51 Merc. (different vendor ). I ask if it was sleeved, I was told it was not, we will see. I see no reason to sleeve a new master cylinder, or wheel cylinder. As far as the wheel cylinders we used , that the sleeve popped out of, they were ordered over the phone, the catalog was not referenced, and the vendor on the phone did not offer any information to the fact that a new wheel cylinder was sleeved, and being a new cylinder, we did not expect it to be sleeved. -- Jim
