What size on the brake cylinder??

Post by 528iE12 »

Hello all E12 people!
I need a repair kit for the main brake cylinder, but in the shop there are two different sizes on the diameter, 23,81mm and 22,2mm. Which is the right one? The car is a 525 from 1975, left-hand drive:)

It would appear to be the 22.2 one. But that's just going off Realoem, I have no knowledge on this other than that. Occasionally the size will be cast into the outside of the M/C, but not always. But even Realoem isn't clear on this one.
