Rebuild K/H Calipers Versus Remanufactured???

.. That's an interesting point you make about these calipers being unsleevable. You might well be right. I could've sworn I had a set of them brass-sleeved by White Post years ago, but it's possible my memory is messing with me.

Your memory is still good. White Post still sleeves them in brass and Stainless Steel Brakes used to sleeve them in stainless steel. I bet you haven't had to do anything to those calipers either...
