Yeah, the brake touches the rim. But some rims are machined for brakes, others are not.
My polo bike has a non-machined front rim. It sqeaked for the first week or two when braking, until all the paint wore off, since then it has been fine. A more efficient person would have simply sanded the paint off straight away, as per Hassan's suggestion.
