How to compensate broken thread in brake barrel adjuster? On my disc brakes I realized the barrel cable adjuster has its thread broken and most of it is stuck inside the calliper.



The picture is not my brake but they are quite similar: the black barrel thread is broken and a part of it is stuck in the silver-y thing on the calliper.

I asked the support of the manufacturer and they say the spare part is not sold separately (and I don't know anyway how to remove the broken bit from the calliper).

Right now I just live without it, but it is quite neat to fine tune the brake cable length.

What are my options? Are there some "standalone" barrels that don't require to be screwed in the calliper? that could maybe be directly inlined in the housing?

Should I show it to my LBS and hope him to have some more or less compatible part in his magical drawers?

Should I buy a new calliper (&lt;-- yes, that's overkill,.. but well...)
It would require replacing your brake cable housing (and you may want to replace the cable at the same time) but there are brake cables with inline barrel adjusters. In these, the barrel adjuster is usually situated somewhere between the brake lever, and the braze-on at the front of the bike. They look something like this and are sold by themselves, or often included with the cable housing.  As your local bike shop and they should be able to get you something that will work.
