Previously, I had posted how I broke the bleed cylinder off the right front caliper on my 2001 BMW R1150GS. I tried many things to solve the problem as I didn’t want to buy a new caliper for $400 from BMW. It’s good to have friends!
I tried many things, and received a number of suggestions from people.
The first thing I tried was the extractor set below. It didn’t do much.
Chris from Affordable Beemer Services in Manchester, NH was very helpful in his advice and patience. If you remember, I stayed with him on my trip earlier this year. He confirmed that BMW used red thread locker and this was not a rare issue.
I tried a small torch first, but it didn’t get the caliper hot enough to brake the thread locker.
Chris suggested putting it in the oven at 260F for 20-30 minutes.
I tried that twice to no affect.
I tried the screw type extractor above, which I wouldn’t recommend using again for this type of issue.
The fluted extractor shown above with a t-handle is the recommended way to remove the stupid cylinder from the caliper. It didn’t work for me as I had screwed around with too many other things so there wasn’t enough metal for it to grip.
I broke down and sent the caliper to Chris. I wish I would have done that in the first place. Live and learn I guess.
Chris tried his best, but I mangled my caliper too badly for him to fix. Darn! He found me a good deal on a used caliper from a ‘92 R100RS which is identical to the caliper on the 2001 R1150GS. He packed it and my mangled caliper and sent them back to me.

I have a nice collection of extractor tools now should I stupidly brake another fastener. Even after all of the tools, the new brake lines, shipping, and the caliper this still cost less than letting the local BMW dealer fix the original broken brake line. I learned a few things along the way too. It was also nice to have other bikes to ride, so I could take my time with the repair.
A huge thanks to Chris at Affordable Beemer Services in Manchester, NH! I couldn’t have done this without his guidance and help. Now to get the “new” caliper on the bike and bleed the brake system!
PS: a machinist thinks I can still save the old caliper, so I’ll explore that in the future.
