on my 2001 R1100RL.
Hope I don't wear out my welcome on this forum and also hope someone can answer a question regarding the rear master cylinder.
I have it all apart looking for anything that might be preventing it from moving fluid to the rear caliper. My question in particular is concerning the O-ring. As you can see in the attached photo, the piston has a groove in it that measures just under 8 mm and the O-ring has an inside diameter of just about 12 mm.
it seems to me that the O-ring should fit snugly in the groove on the piston. What do you think? And also can I source just an O-ring that would work?
Thanks for reading this and I hope someone can steer me in the right direction.
