My concern would be the possibility of the crack spreading into a critical area. This may be very unlikely, but I'm not the one taking the risk. Is it possible to find a correct used caliper in a salvage yard or an 'autojumble', that could be sent for rebuilding? If not, I'd price the W123 caliper conversion before making a final decision.

Happy Motoring, Mark

i would not use that caliper.

cracks never get smaller. and that one has nothing to stop it from getting bigger. it will crack up into the sealing area before it is over.

trying to price up a 123 conversion. But this will probably involve buying second hand units and refurbing. Or refurbed units. Although 123s are a lot more common here than 115s (who's calipers are becoming hen's teeth) I haven't found any yet.
I'm thinking I may just put it together and throw it in. Then keep a very close eye on the crack (i.e. every couple of days)

If so, there should be a lot of W114's out there at the local junkyard. I have one in the basement that is marked "38" that is a rear of a 115.

It was not that smart for the overhaul place to don one caliper. The pair MUST be the same.

I've overhauled 2 cars worth of these ATE calipers without ever having a leak problem.

The hard part is cleaning the square o-ring groove very well. Access and visibility is not great when you can't split the caliper, but definitely do-able

The kits were very cheap and the chrome plated piston that seals on the o-ring almost never goes bad.

Yeah they'd be the same. Just so long as they're ATE calipers, not lucas or bendix. I'd be very interested, where abouts are you? How much would you be looking for one?

I agree the rebuilders were a bit out of order, because I now have no options unless I want to waste the money i spent on the rebuild. I have to have a rebuilt ATE. Or spend a whole lot on something else...

Local car wreckers are useless I'm finding, haven't seen a 114 or 115 wreck at all. If I did I'd be over the moon.
