They are high performance 14.8" Brembo Brakes. They perform differently. Since a few people are having an issue let me see what's up.

Brake dust is normal they usually use higher performance pads. These brakes perform amazingly. I did hear a squeak a couple times and it was going at low speeds cruising with a very unclean car, similar to my Jun BBK on my GSh.

I guess I have a vested interest now lol.

We supported a local dealer (Raleigh NC) with a set of front Carbotech 1521's for a recurring brake squeal.

Service writer indicated

-Very particular customer
-1521 significantly reduced dust
-No reports of squeal

District service rep is/was aware and I am pretty certain they were warrantied for the customer. If the squeal and/or dust is bothersome you may want to talk to your service rep.

We looked at the OEM pads. Made for Brembo/Lexus by Pagid iirc. Brembo uses Jurid and Ferodo as well. Yours is not the only Brembo equipped car to suffer excessive noise/dust.

Quiet for 1 week. Then squealing ever since. I don't really mind other people listening to the squeal in traffic as I run the A/C 95% of the time. I also won't mind switching to another company's brake pad if necessary. I DO mind that Lexus hasn't figured this out since 2010. There is an interference or harmonic imbalance somewhere that an engineer, as is his living, should be able to nail down and solve. Lots of auto mfg use Brembo, so why the issue? And yes, I have a life and as an electrical engineer, I don't give my Clients a finished project that blows fuses or relays from time to time. Otherwise, I really love this car. Well, the ML stereo is pretty weak, but I will get that resolved myself.
Many Brembo OEM setup's are noisy and all are dusty. They use good metallic brake pads with lots of carbon to absorb heat and soft rotors for great bite. Euro brakes. No good in the US

Squeal however is very difficult to control with the fixed calipers and aggressive pads. And I am pretty sure Brembo decides on what pads if they are going to put there caliper on it.

When the yahoo in the Nissan Quest raises eyebrows just smile to yourself.

Default Carbotech Pads

Just want to cheme in with my Brembo brake squeal experience for my 13 F-Sport.

The squeal was very obvious on my car, loud and gradually happened almost all the times, maybe 95%. It was not the usual low speed or cold morning occurences. It squealed more and more, louder and louder as it got warm/hot. The noise bothered me so much to the point where I didn't even want to drive the car.

I brought the car into the dealer twice. First time pads were replaced and bedding was done.

I did a lube job on backs of pads and all metal contact pts. No help.

Second time was at a different dealer (March 14). To show you guys how bad the squeal was, the shop manager noticed the noise at his very first press on the brake (within 15 feet). The rest of the drive with me was just to comfirm and to make it back to the Service drop-off, all within the dealer parking lot, and it squealed everytime during. Shop manager told service adviser "it's a go". They proceeded with TSB L-SB-0008-12 and again ordered and replaced pads from Brembo. Took a week. Service tech also did bedding and reported no squeal or noise. Well, it squealed again about a week after. This time maybe about 80% of the times.

Though for my normal street driving, the brake never got faded nor lost any effectiveness. But the squeaking and not being able to drive and enjoy the car that was what made me look at aftermarket pads.

Last month I called and talked to Carbotech and they confirmed their CT1440-1521 does fit my car, which I couldn't get any fitment confirmations from any retailers I asked. So I took a chance and ordered a front pair through one of Carbotech retailers. Took a week to arrive I swabbed the pads myself and here's what I noticed, after 250 miles driving:

1. Virtually the squeal is gone for me. I don't think I heard any. I can't confirm this for anyone's experience though.
2. Dust is reduced to about the same or less than that of the rear, which are non-Brembo and non-squealing
3. The "first bite" is not as dramatic as before with the OEM Brembo. I didn't mind the Brembo's "first bite", and just learned to live with it. Now with Carbotech, the feel is a bit smoother. This might or might not be good for other people who has more aggressive driving style than mine. But I like the change.

BIG NOTE. Although the physical Carbotech pads fit our 13 F-Sport Brembo set up very well, there seem to be an issue for me to clip back on my car's pad wearing sensor. I am attaching a picture for your view; Red pad is Carbotech. Basically, the Carbotech pad is missing a secondary thinner slot for the wearing sensor to clip back onto. I have brought this issue to Carbotech and they are working on meassuring and making this secondary thinner slot, as this moment. Right now, I am running my Carbotech pads without the wearing sensor installed; I just ziptied the sensor safely around the area. I supposed I could dremel the slot or bring the pads to a machine shop for the cut. Still have a while to worry about it. I would advise checking or talking to someone at Carbotech before ordering.

Sorry for the long post guys, and I am not endorsing anyone here. To be honest, I have never bought a $200 brake pad in my life, and I don't know at this moment if there are other pads available out there for our 13+ F-Sport. I don't know if the will squeal again in the future even with these Carbotech pads, but so far I am enjoying the less dust and the squeal-free
