Brake Pad Change...Unhappy :X
Maybe some guys can help/guide me here. 
Couple weeks ago, I purchased the Hawk Ceramic pads to replace my front OEM dusty pads. Apparently these are suppose to reduce dust (Which it DEF did by ALOT) AND eliminate squealing, HOWEVER they are still making noise. Why would they still be noisy? Was it something that went wrong with the installation of them, or maybe my rotors need to be resurfaced? I have NO IDEA, I'm a newB with brake pads. Hawk's remaking these pads...well so I've heard, could it be a fitment issue that is causing the noise?
Secondly....I now noticed since my new wheels are on that the rear pads aren't quite dust free either. I have been on those oem rear pads for about 15k miles now, what is the life expectancy of pads usually? Could they be over dusting because they need to be replaced?
And is that something I can get done my next servicing? Thanks in advance fellas!

Nothing will be quieter than OEM pads. Hawk or any other aftermarket pad is going to be more abrasive/make more noise than OEM. Only way to get them quiet is to do a few hard stops but the noise will come back.

hmm, mine (OEM)stopped making noise a while ago, maybe I have just aggressively bed them. What kind of driving do you do exclusive? When things get hot they seem to bed better and elevated temps may be required on the ceramic compound. Hawks work alot on material transfer to the rotor, so perhaps some more high temp bed in will solve it.
I will be swapping to HPS to test them and give you feedback once I do.

Now your pretty much telling me that I'm not getting them hot enough, so I should go out and spirit drive and break them in now hard? What pads are you on now? OEM? Oh and can worn down rear pads become overly dusty? How many miles are life expt of pads anyway?

The life expectancy really varies with how hard you drive it. On lexusF.com some of the guys on there their pads are almost done around 15K while some are still okay at 25K. I would imagine the OEM brakes to last longer than hawk pads. I bought hawk pads like 5 months ago but I still only have 8900 miles on my F in over a year. I don't have them on yet because I wanted my OEM brakes to be almost done before I put them on.

Again...Does anyone know if a low/worn pad actually causes MORE dust?

I have the hawk ceramics and have been running them for the last 5-6K miles or so...there is a bed in process you need to follow....It was several stops from varying mph and when done, they were damn near smoking...you then were supposed to let them sit for x minutes, etc.
- they are MUCH more quiet than stock, and immediately so. No squeaking until just recently when I get a slight chirp when coming to a very slow stop, such as stop signs or parking in my garage.
- the dust is is still there, although it seems to be less heavy and lighter in color.
- the brake pedal feel is a bit different, not the initial bite of the the OEM's.
My rears have always dusted but not as heavy as the fronts as the fronts take most of the braking load...

^^like mondo said i have no noise watsoever. i get it rarely once in awhile when im slowing down by braking but if u did the steps they told u to do when u first install them. yes the brake dust is not as much as the stock but its an improvement. most of the time its my rear oem pads that is making the noise.

Pedal does feel different a bit more giving, but thats alright with me. Not sure about you but my dust has significantly reduced from the OEM pads. Those things were a freakin NITEMARE!!!!! ^^like mondo said i have no noise watsoever. i get it rarely once in awhile when im slowing down by braking but if u did the steps they told u to do when u first install them. brake on them hard and then do a couple of soft brakes continuously. yes the brake dust is not as much as the stock but its an improvement. most of the time its my rear oem that is making the noise.
What's up with this fitment issue thing on the Hawk pads as well? Can the vendor "CIRCUIT" chime in on this one? THANKS GUYS!

I just replaced my front pads (actually last week) for the first time, I got Hawk ceramics. My front OEM pads were at like 2mm when I replaced them and they were squeaking for the past couple of weeks. My rear pads are at like 7mm after 20K miles, so they can last for another year or so. My rotors (front and back) are fine per my local Lexus dealer, they don't even need to be resurfaced.
Installation was soooo easy that I'll do it myself next time (I went to a Good Year shop). The mechanic told me that this pads are great, and that I don't need to follow any bed in process. Well, I followed his advice and have been driving my car for about a week now. The first day I noticed a pedal feel way different, kind of mushy, and it took longer to stop than before. After the first day I can feel everything back to normal, same brake pedal feel, same braking power, and no noise/squeaking at all. I've been wondering if what it came inside the box was actually ceramics because they stop just as OEM, brake dust will tell...

Hey Sam,
I got these 4 months ago and they are great
I had a customer of mine install these for me-he's an Infiniti Master Tech and worked for Chrysler/Jeep/Dodger in the past so he has plenty of experience with Brembos.
Since I only had 4k miles on my F at the time he only gave the rotors a light sanding to remove the pad build up from the stockers of the rotors.I know you have over 15k on your F so hopefully you resurfaced the rotors or at the least had them sanded down b4 installing the new pads.if you didn't do any of the 2 you will prob keep squeaking.As for the dust out back-mine still dust but nowhere near as they did in the fron-and Hawk still doesn't make a pad for the back.Mine front pads were bedded in and I don't have any squeaking whatsover but occasionally the stock pads in the rear squeak like they did since day 1.The reason you notice more brake dust out back now is cause you have a polished lip as opposed to the gunmetal from the stockers,I too notice the dust more on the back wheel b4 I can the the front and it is always on the polished lip that I notice it not the spokes.

Glad to see your feeling my pain now with the rears as well.
