I'm replacing the discs, parking brake shoes (down to bare metal!), and hopefully rebuilding the calipers on my '83 300TD (173K).



It's my understanding (from Forum and FSM) that the wagon calipers have a larger piston (42mm) compared to the sedan (38mm). After I pulled them I measured the pistons in my calipers (ATE) and both both have 38mm pistons. I assume they are not original but I have no way of knowing -- I have only had the car 7 years. The piston seals did say ATE so they must be fairly old.



I was planning on rebuilding the calipers if they were in good enough shape -- and that appears to be the case. But since they are not the (supposed) stock size I am wondering if that's the best option. They have been stopping the car well enough for my 7 years of ownership.



I could rebuild these calipers (least expensive option).
I could buy rebuilt wagon calipers (more expensive but harder to find).
I could buy new wagon calipers (most expensive: almost $500 for both!!).



Suggestions?
