Rebuild K/H Calipers Versus Remanufactured???

Dan,
They may have been sleeved. After all, its not an impossible machining task, just a hard one.

Nice find on the stainless pistons. I had looked a little before deciding it was more work and time to rebuild than I had available. So, if you just read between the lines a little of what above I think you'll complete the picture.

The pistons in my rebuilt calipers are supposed to be stainless and probably are. They are magnetic, but as you know, there are commonly used 'stainless' steels that are magnetic as well as ones that are not. The boots are of US manufacture and thats about as far as I went in checking over materials.

I'll edit and insert pictures. The reason I did not clean and reuse the bolt is because of the way it had jambed and the critical job it does. I went for the 12 point bolts because they have a little higher tensile strength than SAE Grade 8. It's also the type of bridge bolts shown in the service manuals and MTSC booklets. However the later booklets show standard 6 point heads on the bridge bolts. I don't know if the illustrations are exact representations of the particular years - someone familiar with concours or factory correct restoration could tell us.

It is my understanding that there was a somewhat substantial change in caliper design on 11/2/1967. Calipers after that date had second groove for the dust boot. That's all I've every had.

Anyway, some pictures of the piston and caliper that was hanging up this Spring. This tends to happen when new pads go in. Oh well.
