Having new tires put on today (Tire Rack / Yokohama Avid Ascend GT - USD$143/EA) and the install shop pointed out the rust on the rotors that look just like these pictures and quoted me > $750 for the 4 rotors and pads. The pads still have a ton of life at 54K miles. I also have had no braking issues and get high braking scores. I'm glad I checked this site and see this wear, or rotor rust as the tech called it, is common and normal. Reading down the thread a little, I see a lot of talk about regen braking. This is my first hybrid. Could someone please explain how I should be braking? Do the pads actually hit the rotors when braking and the brake display on the dash shows the braking animation (I don't know what to call it)? What is the difference between friction braking vs. regen braking? Is there a best practice I should follow for coming to a stop?
