I just put the Hawk HP+ too I did them with DBA 4000 Slotted rotors all around.. WOW they are loud dude i tried everything. I did the grease i bedded the SH*t out of them almost got into like 5 accidents doing that one.. But seriously my car is loud with the GT Spec Headers and the N1 and these things SCREAM.. When they heat up and if I am doing aggressive braking no prob a light squeal.. But stopping at a light and driving around town I just see people looking at my like damn he needs some brakes from 20mph - 0 forget about it these things are crazy loud... So its not just you its the pads.. But with that said they stop the car on a dime, once they heat up they are so aggressive i love them. So I am gonna take the noise trade offs i guess you know what can you do... Or maybe go to a Ferodo 2500 not sure if they are quiet or not?/

I purchased some HP+ pads per a recommendation/helluva deal. Mind you, I'm a car n00b, but I'm learning. I love them and think it's night and day compared to stockers. Significantly more brake dust, obnoxiously loud, but stop a hell of a lot better than the stock pads. After a few months, I don't really notice the squealing any more, until someone tells me I need new pads of course. ;)

SOLVED!

So I had used some CRC Disc brake quiet originally, this stuff:

I appplied it all over my pads, shims, etc, and its a tacky goo that eventually hardens up. Well long story short after a few autocrosses, I decided to take my wheels off. Long story short, this stuff looks like it had been lit on fire, and was like "bubbled" fizzed up all over my brake pads/shims. It had pretty much fused one of my shims to the back of the pad, which I had to try off with a flathead screwdriver.

I then proceeded to take all the non-sticky but stuck onto my caliper rubbery like red stuff off. This was pretty much a manual process, and there's still a small amount still on there. I fully cleaned my pads, calipers, and removed all shims.

This time around I had bought some CRC Synthetic Brake & Caliper grease.

This stuff:
Image



I did not use any shims. I applied it fully to the back of all pads, alone with any metal contact points of the metal bracket that holds the pads in. This includes where the pins rotate on the metal bracket, (Rotate + no grease = squeak) and where the bracket pushes down ontop of the caliper. This grease includes a brush built into the cap which was nice and made it very easy for application.

It's been over a week now, and my Hawk HP+ pads are aboslutely silent. I've beeded them in "again", and they're running GREAT so far. No noise at all! (and it's been 80-90 degrees here everyday for the last week)

My theory is that the red stuff hardens from a tacky goo into well, rubbery like material. The synthetic grease though remains, well, as a grease. Therefore, it's always "gooey" and provides for better lubrication. (preventing squeak)

I highly suggest any of you who had brake pad squeaking problems to try this grease out!

I too have HP+. They provide some sort of grease in the box. I used it w/ the shims. Greased up all moving parts, similar to what is described above. I am really not sure what the job of the shims is though. But hey if its there might as well put them in.

My experiences is that they were dead silent for about first 300 miles post bed-in. Then they developed a slight squeal at light brake application. A few hard stops and then its good for a while.

Acejam2k:
Now I have a question on the CRC stuff. Do you feel that is what has solved or the fact that you bedded in the pads?
In my case I think its the bedding in part that cures it.
Also, do you think the noise will come back with time?

Well, even before using the synthetic grease, I bedded in the pads several times, and even did a number of autocrosses on them, they were definitely bedded in. (I managed to get my rotors to turn purple from heat/gasses)

Hopefully the noise won't come back, but it's been just over a week, and I only heard 1 slight split second squeak yesterday, which has not come back. This is a huge improvement than before, as previously my breaks would squeak when not even using them!

My theory is that since the grease is synthetic, it allows for higher temperatures. It's also a true "grease", and not a tacky goo that then hardens into a rubbery goo stuff. Squeaking is caused by vibrations, therefore I figure taking out the metal shims will only help.

Don't forget that the CRC stuff you first used is not meant to be used with pads that require shims. Not sure if that was the source of your problem.

I use the shims with my Ferodo 2500's with the CRC spray stuff that can be used with shimmed pads - they have always been silent. -> they weren't without the shims on the rears with the same CRC stuff. They screeched like crazy until I put the shims back on.

Wooot ppl with the same problem as me. Thought I was like the only when I was searching on the Ferodo DS2500 brakes and everyone said theirs were quite.
They make high pitched squeel only when they are warmed up and when i'm slightly applying the brakes or slowly coming to a stop. If I press hard on the brakes they don't squeel and if they cool they dont do it either, found it really weird.
First time I used the stock shims w/ CRC Disc brake quiet, that didn't work so i cleaned it up, got rid of the shims, put more gunk on the pads instead and had the same problem.

I will try CRC grease this weekend and see how it goes.

I used your technique with the CRC synthetic grease and no shims. Brakes were quiet for a couple of days after bedding them in - only occasional light squeal. After tracking them this weekend, the mofos squeal like none other from 20-0 mph. They started squealing at the track too. Have yours stayed quiet?

A quick update to this thread:

So it seems my pads started squealing again. :mad: This time loud, I mean REALLY loud.

Winter is on it's way, so I decided to take the pads out, and put a new set in. This time around I picked up some StopTech-Centric Posiquiet pads from TiC. $85 for all 4 corners, what a deal!

These pads have pretty much the same bit as the stock pads, but barely dust at all, and are completely silent. The only hook is, they are for street driving only. (no track on these)

I figure, this will be a perfect set of pads to get me through the long New England winter, as I don't want to be constantly cleaning my wheels from dust in the cold. Come springtime, I'll put my HP+'s back in, and lube them up again. It seems that the synthetic grease left my brakes squeal-free for a few months.

So far I'm really happy with these StopTech pads. I did not use any grease on them, only the shims that came with them. When I took the HP+'s out, my caliper had tons of grease all over the inside of it. I cleaned them out significantly using a few sponges, brake cleaner, simple green, and a hose.

Actually i have had this problem as well! they break great! great pads but it is annoying/embarrassing that the pads are squeaking everywhere!
What i found to work is to drive while slightly pressing the brakes and on the gas to warm up the brakes, do this for like 5-10 seconds and the squeeking stops.... it comes back when they cool back down but just do this again and problem solved :D that works for me at least.... as grease just works for a coupld of days...

Yeah same here.... I like the noise. I love modulating the pedal to make them squeal as loud as possible when I come to stop in a line of traffic. Definitly gets the heads turning. I have also had many bystanders comment that I need new brakes. I used to explain, but now I just nod and walk away.
