The seal replacement??! Help! Is my 1975 R90/6 different? I did not pull out two rings. There is just a single seal. I paid a crazy $39+ for it from Max BMW.
Big outer seal you see without disassembly is your dust seal. When you remove piston, there is rubber oil seal. Not having that one would make calipers leak so it must be in. Take a closer look. Good luck and thanks for watching!
@@mikeinsw11 that’s interesting and I’ll give it a try. I was using brake fluid as lubricant here indeed. Thanks Mike for the advice and thanks for watching!

The pistons go in easier if you use a rubber grease. Your difficulty was probably because you used brake fluid to lubricate the piston.
