I decided it was time to pull the canti brakes off my LHT and do some cleaning and lubing. I got everything off and cleaned the parts and canti studs.
I can easily grease the studs and put everything together, but it appears that the inner sleeve (that goes on the canti stud) rotates within the brake assembly, and should be lubed. Is that right? If so how? It doesn't appear to come apart. I could drip some oil in there, but that doesn't seem like it would last long, and I don't want oil weeping out and getting on the rims and pads.
