I don't think anyone told you to replace them outright. We suggested that you perform tests in order to rule them out as an issue. We are trying to save you money by providing you the tools to troubleshoot these things on your own and specifically NOT to just shotgun parts. My initial inclination was rotor lip rust rubbing on something... but there are processes that you can perform very easily to try to rule out other possibilities. For instance, if it hadn't been a rotor rub, and you had just turned the rotor for no reason, you could have wasted money. So until you performed some simple tests, I didn't want to suggest exactly what to replace/fix.
The EASY answer is to take it to a shop. But you have to pay for that answer. Just a matter of what you want to do - pay? or sweat a little and save some of that money you've been earning. Start calculating cost in terms of "hours you have to work to pay for it", and it will change your tune.
