Yes in the early days of cycling the brake rubbed right on the tread.

Btw on the subject of brakes, IMO the best way to go is disc brakes. That way the rims can be designed for maximum strength, and given a aero shape. Replacing pads or discs is very easy. Rim brakes wear out rims, and require an expensive rebuild. Most cyclist can replace their own discs and pads no problem.
