Hello Guys,

I'm changing my front brakes as there is around 2mm left of brake pads. Oddly, this time the front brake sensor didn't light up like last time. I was told that for all new BMW, Mercedes, and Nissans too that you are suppose to change the rotors at every second brake change. Sometimes, I only think that is a way for the dealership to make money. Since you have the brake pads off, why not change the rotor and charge the customer the labour time and make the parts money. My ML320 has the following thickness..

Front Rotors: 24mm
Rear Rotors: 15mm

Do you guys suggest changing the rotors as if what I said above is true, its time to change them. I noticed scoring on the rotors near the center on both sides. Anyone know the min. thickness specs?
