Not sure how that is harder than changing a tire... I mean, I think changing a tire is more physical labor than adjusting the brakes. Have you taken a look at various videos on youtube and/or looked at websites? Usually it's just a few minutes with some Allen keys to get them right. Worse case, you don't get the toe quite right, they squeal--and you then have to stop and adjust the toe slightly (depending upon what the setup is).
