I dont live in climate with salty roads.I had to replace my brake rotors and pads twice by 42,000 miles. About every 20,000 miles due to rust and uneven wear. The problem was I did not use the brakes! Always used regeneration braking. After the second expensive brake job, i started to put the car in neutral going down a good hill, and used the brakes to slow me down. With the car in neutral, it ensured that the brakes were being used to slow the car. My last visit to the dealer for a tire rotation, i asked that they check and clean around calipers. The service tech came out and said the brakes were great and clean, what are you doing to keep the brakes in good shape. I told him about using neutral on a hill occasionally, and the actual brakes used. Keep it up, it works, your brakes look great.
Driving in Neutral in most states is illegal.
We have a Volt with ~90k miles and the brakes look new. TX and OK car. Climate makes a huge difference.
