Listers,

Our host used to market a rear brake caliper that is no longer available. They don't mention who the manufacturer was, only that rebuild kits are NLA.

They also list an Ate/Teves caliper for half the price of what they were selling the original for.

What's the story here? Does anyone know if the caliper pistons are the same diameter? Are there any compatibility issues that one needs to know about?

Last, did Ate calipers ever come from the factory on the rear of a W123? I'm thinking that perhaps they used only Girling or Bendix. I have a '84 which might have Girling rear calipers on it. FWIW, I already have Ate replacement calipers on the front.

Thanks!
