Hi Bruce,

I can tell, the lure of physical maintenance vs. this virtual stuff, has removed you to more interesting places, as it should me as well.

Sort of on-topic, given the tendency for remanufacturers of brake parts to assemble things haphazardly, the Brickboard may have been the foremost place to learn about mismatched caliper halves. Not myth, but frustrating reality.

You posted http://www.brickboard.com/RWD/index.htm?id=926014 some time ago, also under a heading of "Slightly Off Topic". I promised to look at some of my parts pieces and since offered some pics of the Girling innards I examined to be better able to explain the difficulty bleeding mismatched calipers. Photos don't explain it, so I finally sketched what I saw schematically here, as you suggested.

I thought your description in that post represented the height of eloquence in transferring a visual concept into language.
