I have always been an Infinity owner. My wife drives the 07' M35 and I drive the 06' M45. We've had 3 different I30 and I35s and an 07' FX35.

The problem is with my 06' M45 sport. I bought the car used about a month ago with 10,000 miles on it. The car is like new in every way.Since I bought it, the brakes have had a little grinding feel in them.I took to the dealer, they told me the brakes had rust on the rotors.They said it should go away on its own. After 2 weeks of driving, the grinding seems worse not better?? Also, now the grinding seems to continue for a few seconds after I take my foot off the brake.I am very annoyed at this point. Anyone out there have advice for me.I am not one to do my own breaks.

Look at the little metal, stainless clip on the caliper that rests under the pads. You can probably do this with the wheels on. If that clip is bent out too much, it may be contacting the wheel.

If you can, jack up a front tire & see if the grinding is present if you turn a wheel. Then take a wheel off and see if the rotor spins free (or close to it).

The Rust on rotors response from the service writer was a "tell him something to make him go away" answer. Pretty much all rotors will have some rust on them and if you used the car at all prior to them looking at it, the rust was removed as you pulled in and stopped in to tell them you were there for service.

The next action, after finding a grinding when you looked at it, is to take it to a place that offers free brake inspections. Take their information with a grain of salt and DO NOT use their recommended services. Just make sure that they don't come back with "you have 5% remaining on your front pads and you are down to the wear indicators" as an answer to what might be wrong.

If they say a caliper is hanging you'll have already found this out when you looked at the front wheel yourself. The free inspection place is just to confirm it. Take it back to the dealer & ask them to check for a hung caliper.

ThanksThat makes perfect sense.It does sound like the dealer was just pushing me out the door.I will check that caliper right away.

Really?? Always an Infinity owner? For being a lifetime Infiniti owner, I hope your browser has some kind of automatic spell check.On another note, being able to find a 3-4 year old car with 10k miles is pretty rare.
