Just got a used G37x sedan. Looks like 80%+ pad left on front, ~ 40% pad left on back. On a hard stop when I get the brakes hot I'm getting vibration indicating most likely the front rotors need resurfacing but I can tell from the lip on the rotors that the rotors are original (car has 40K miles on it - was a corporate car with lots of freeway miles) and the pads are probably replacements.

I don't want to dump unnecessary money into this car but the vibration is bugging me. Was thinking of starting with a set of new front rotors. Although on my Brembos on my Volvo, the dealer was alway emphatic about replacing pads when replacing rotors since the pads are already 'grooved' to the worn rotors. Seems like overkill and a way to get more service dollars as the new rotors should wear any irregularities in the pads down or at least reduce them.

Wondering what people recommend. Again I'm not tracking this car just driving it old man style and don't want to spend more than necessary.

Should I go with just aftermarket solid rotors, or should I also really get the pads too and if so which ones? I've read cross drilled is better than solid in dry braking, but are they worth it and will the dealer have issues with any warranty claims on the brakes if they see drilled rotors? I try to stay away from slotted as you can't really resurface slotted without defeating the purpose of the slots somewhat?

Educate me oh G Gurus!

 

AP RACING! lol

 

If the car still on bumper to bumper warranty are the rotors covered or not since they are a 'wear' item? I know the pads of course are not.
