    First, a nit-pick; its brakes, not breaks.

    The tabs are called "wheel guides" and they help guide the tire between the brake pads to speed wheel changes. They can be useful for racers where a flat tire during a race calls for a very fast wheel change. They are less useful for the rest of us where saving a second or two during a wheel installation is not an issue.

    They are called 'wheel guides', but as far as I can tell, they don't actually help with getting the wheel back in after a flat. I've never actually seen them be useful, so I'm inclined to thing brake manufacturers had some ulterior motive in adding them.

    They help prevent the wheel from suddenly stopping against the flat surface of the brake shoe itself. It *does* make it easier to replace a wheel blindly or in less than ideal conditions where speed is paramount (e.g race flat fix).0-

    If those were useless maufacturers would've removed them immediately and promote that as "weight savings". For example the new 7900/6700 groups still retain brake shoes on their calipers with the guide fins.

    So, um, what are they doing on a touring bike?

    You realize a feature of convenience does not only apply to the one specific application I mentioned right

    Yep. I suppose. I am in no way shape or form any kind of an expert but i have had several bikes pass through my hands in the last year or so and the only one to have this "feature" is a touring bike made during the company's "huffy" stage. Just make one wonder is all.

    Before tightening the brake anchor bolt, I find the tabs are a convenient place to squeeze the calipers close to the rim without using a third-hand tool.
