    one of my V-brake post isn't centered

    Converting an old bike into an SS. It originally had cantilever brakes but I'm replacing them with V-brakes. I noticed that one of the front post/boss isn't centered. Looks like it was slightly dented at the base too--from the factory, from what I can tell. If you look at it dead on, you can see that it points a tad toward the left. The V-brake arm slides on fine, and once both arms are on, you couldn't tell that one post was off center.

    Now, I'm not sure if this is a problem, but right now no cable is attached, so naturally the arms flop down and away from the fork. The arm that's on the off-center post holds its vertical position but will easily go down if you manually push it down.

    I tested to see if the arm would return to normal position if it were cabled up by squeezing both arms together as if the brake was applied, then I released pressure and both arms returned to normal position. So looks like the tension spring works normally on both arms.

    Does this mean it's all good? This is the type of V-brake post that can't be removed from the frame, so I have to deal with it the way it is. It's a '96 Raleigh M50. Decent quality but a bit disappointed that a defect like this came from the factory.

    Should not be a problem. That is certainly one of the benefits of cantilever/V-brake bosses. The tolerances are much easier (larger window). The pads will adjust rotationally and vertically as well as fore and aft. This means you should be able to get the pads to contact the rim without any issues (provided the vertical travel is fine.

    If that's the case, the brakes will work fine.

    Good luck with that.

    Thanks for the good news. All went well. Both pads are centered, but I did notice that on the off-center post, pad bolt was at the bottom of the vertical adjustment while on the straight post, the pad bolt was a just a tad off the bottom. Not really noticeable, but I' very picky about these things. Thanks, OCD!
