It does not happen all the time, but I've heard it 3 times this past week, during slow speed came to a complete stop. According a guy who does a lot of work on 3IS this is a known issue with this car, the problem is the brake pads. Anyone else noticed this?

From what I know.. this the norm for performance brake pads. If you want quieter ones, check our ceramic pads. Akebono makes pretty good ones.

(Someone correct me if I'm wrong)

So my IS350 F Sport came with performance pads?

Yessir. You should also noticed that your front wheels are coated with brake dust. Cons of having performance brake pads.

If you're hearing the noise after the car cold soaks (sits for 8+ hours without moving) for the first couple brake applications, it's pretty normal.
Where the vehicle parks, the weather, and ambient temperature are all contributing factors.
The OEM pads are a compromise of performance, noise, and wear.
The ceramic pads above will give you less noise, less dust, but also less performance. Although as noted many times on the forum, unless you're tracking the car, you probably won't notice the lower performance from the ceramic pads.

No I was hearing them (again, not all the time) the car was not cold, it had been driven for a while.

to complicate the matter, I already had my brake calipers painted, if I take to the dealer they'd just say it had to do with the calipers painting which i know for sure isn't the case because the squeal was there before.

I went over this before. It's not an "issue" Embrace it. You bought a car that has performance brakes. If you want camry quiet, you get a camry.

I've went into the technical aspects of why this "issue" happens. but I'm tired of typing it out every time someone posts this kind of thread.

In short, it's not an issue. It's awesome. you WANT noise to happen. It's GREAT it's happening. Don't sweat it.

You can "fix it" but it'll come back promptly. IT's inherent to the design.

Wash your car often and it'll help mitigate the noise somewhat.

^^^ thank you E46( a BMW old timer I see ��), I hope that's the case, it's a brand new car that's why I'm sweating on every minor imperfection I can find. I will probably not even notice this anymore as time goes by.

my 3rd gen IS350 F sport squeak like hell, but the braking power is Awesome, well live with it
