OK, I misunderstood. I read your post literally, which means I understood you to say that they just replaced the rotor without doing the pads or any other work.No, no , no, absent information: pads on all four corners also changed. Front rotors were scared supposedly due to travel on unpaved roads. I could have waited a couple of days for them to be polished or just replaced. Since I live far from any public transport to get home I chose the latter option. Not sure what sounds fishy to you. I am just reporting as maintenance events unfold.
To clarify, just replacing a front rotor without doing pads is fishy. Almost nobody does that.
