    Just had it happen on my partner’s old bike (sentimental value). Brought it to the LBS. They redrilled/retreaded and replaced the brake post. I got the bike back in no time.

  2. These are called ‘brake studs’ or ‘canti studs’ (for the old style cantilever brakes). Some forks and frames have removable studs that thread in and out of the fork/frame. Surly bikes do not. 

    Head to the nearest Surly dealer and have them order you a replacement fork. 

    Replacing the stud would require finding a frame maker or experienced frame repair specialist who can cut the old stud off and braze a new one on, and then repaint the area to prevent rust. It’s highly unlikely you can find someone willing to do that for less money and in less time than it would take to replace the fork. 

  3. Can be replaced. Not by everyone though. So for an ordinary bikeshop all they can do is replace the entire fork.

  4. Take it to a frame shop. They could cut this one off and braze on a new one pretty easily. This is a rare case where repair is acceptable and likely to be reasonable.

  5. The reason you are getting mixed info is because on aluminum bikes those posts are often replaceable (and have a flat for a wrench to grab onto). But many people are misinformed to believe they are ALWAYS replaceable which is not the case… on steel forks, they are usually permanent except to have an entire new brake boss soldered on.

    Problem Solvers used to make a repair part but they stopped offering it. I suspect they stopped making it because it probably doesn’t work well except for in a pinch. The repair part was effectively an extra long bolt that would go deep enough into the boss to bite and hold the post on thus allowing for a functional brake.. you would just reuse the part that broke off or a cylinder of the correct length in its place along with a long bolt. It might require a deeper tap of the boss and it’s a kludge.

    If you have a 1-1/8″ headtube, which a LHT likely does, I’d just replace the fork and be done with it. Think of it as an excuse to upgrade the front to discbrakes. If you had an older Trek 520 like I do, that’s a 1″ fork, then it’s harder to source a replacement.
