Brake discs now avalable 390mm fronts drilled and groved and 345mm drilled and groved rears.
Google Apec brakes, I have a set going on and there great.
Bremo rear pads easy avalable but fitting genuine front pads.

Thanks for the alternative - Zimmermann has been my go-to for Mercedes and Porsche.

my wife's 2014 ML63 brakes are always squeeling when she stops. This is unlike my 2014 ML63. I have the performance package on mine, is that the big difference?

Brakes are the same, performance package increases the boost.

Possibly the difference in how you both drive. She could have build-up on her pads/rotors, you can try "bedding" them to burn it off. Slightly different methods below, but similar.

If that doesn't work, you can (or dealer) take the brake pads off and soak them in BG Stop Squeal. I have the dealer soak them for a while to ensure they are absorbed well.
