My front brakes are squeaking when the car is moving below 5-10mph while the brakes are applied. The rotors seem warped also, probably because of heat. A random mechanic told me that I should get new rotors as it's not resurfaceable, but I don't know if I can/should rely on his opinion. Are there cases where resurfacing (assuming the rotors are still thick enough) is not possible, and I have to get new rotors?
Also where can I buy OEM rotors? I saw a place selling it for $100 each, but aren't there ones for around 60-70 each?

I wanted to get new brake pads as I am going to a shop this weekend. I can get it for $100, parts and labor. The brake pads he is using is Bendix. Seems like they are ok and cheap.

I was looking into Hawk HPS, and was wondering if those are HPS, since the HPS usually have a dark blue package?
