new cantilever brakes don't fit on posts

I've tried googling this extensively (maybe not effectively) to no avail.

Here is the situation:

I own an older Soma Double Cross frame. It has posts on the back for cantilever brakes. Recently, I purchased Tektro CR720 to replace the current brakes. When I went to put them on, they would not fit because the diameter of the posts on the bike exceed the diameter of clearance on the brakes.

I think i'm missing something. As I said, i've tried googling it. I think I may be using incorrect terminology as there are no results that are on point.

Anyone have any advice or resources to get me on track?

It's not that uncommon that the brake bosses mushroom a bit if the brakes have been over-torqued. If your frame has replaceable brake bosses, replacing is the easiest course. Or if you trust your skills, simply go at it with a file until it fits.

Thank you for your reply. Before I go down the road of trying to replace, is there any possibility that I bought the wrong size brakes? I don't want to haul it to my LBS or take a file to it unless i'm sure this isn't me being dumb and buying the wrong brake or something.

Thank you again!

Might the posts have an old bushing stuck on them?
