I just installed a pair of rebuilt front calipers on a '93 240. I hesitate to turn in my cores because the castings are in MUCH better condition than those of the rebuilds. So, I intend to renew them myself.

It has been some time since I went to the trouble of rebuilding calipers, but I do recall that splitting the calipers makes the whole process a lot easier. I also recall that as much as I didn't like it, I reused the seals for the internal transfer ports.

After poking around a bit, I cannot find a caliper rebuild kit which comes with the internal seals - does anyone know of any rebuild kits which supply these vital seals? Or, does anyone know their type (square or round cross-section?) and dimensions?

Thanks, one and all.
