    This is a strange one then. If the pads were not replaced then the pads would be still metal-to-metal and the grinding noise should still be there, machined discs or not. I think it's time to get your hands dirty and take the wheels off and see what's going on yourself and confirm the discs are clean and the pads still have meet on them.

    I had an indi have a look, confirms the pads have meant on them. He didnt take the wheels right off, but hoisted it up and crawled under.

    I can confirm the Pads were not replaced when they machined the discs. And the noise did go away, but started coming back a few days and KM later.

    Worst case, I'll take it to a specialist and pay to get it done. But I'll keep working with the dealer as I'm getting it done for zilch at the moment.

    I'd be worried if someone machined the rotors and re-installed the old pads. There are a very few occasions where you might chance that and none of them include where there was a problem with the brakes that suggested they needed machining. As the absolute basis you need to remove the pads to check the part number as correct (compatible if an aftermarket pad) and to confirm that there is no metal to metal contact on the pad surface.

    This is horse and cart technology stuff and just looking at it isn't going to solve anything. I'm a little surprised that the dealer is doing this for zip so far but at least you are getting what you paid for.

    You cannot machine these break discs!!!! They will need to be replaced immediately. Where in Australia are you?

    Why can't they be machined? Looks like just a standard ventilated disc. So long as they're still within minimum thickness.
