i have the same pads. and when i make my way to work in the morning (only a couple of stops and they are usually pretty hard) they are quiet. but on the way home 1:30 in stop and go traffic they scream. I have had to do the same as you and start breaking harder.
When I installed the brakes i also installed new dimpled and slotted rotors. They did not squeek in the beginning, it started probably 5K miles on the pads

I had a similar issue with rear sets on my C5. Hawk actually has pretty go customer service and sema second set out. The problem seems to be when you use them with old rotors. Honestly at 35k I dump the factory rotors if I were installing new pads. New take off rotors can be had for under $60 from SLP's eBay store. You must bed these properly or they will scream. The noise is caused by the friction/harmonics.

Yea i probably have to swap my rotors out at this point... I have 30k miles just about, and already had my rotors resurfaced once.

How far can I drive before I bed the pads? I have to drive about 10 minutes before I get to a safe spot, will this affect teh bedding process.

I tried to replace my rotors today, sand the pads, and add more grease but I couldn't break free any of the 4 caliper bolts so I just added more grease and called it a day. I'll have to take the car in for a rotor swap.

I have very bad squealing I think from two things. When I run my finger across the rotor surface I can feel uneven ruts or channels and the grease was pretty well worn away. Hopefully the new grease I added today will quiet things down until I get the rotors swapped and pads re-bedded.

FYI - I have Hawk HP+ pads on and waiting to add RB 2-piece rotors.

10 minutes of driving will not hurt a thing. Just don't jam on the brakes until they are bedded, if you can help it at all.

When the new rotors are installed, you will need to resurface the pads again. I recommend 120 grit sandpaper laying face up on a flat surface. Cycle the pads face down on the sandpaper and oscillate in a circular motion until the pad friction surface is dull and even.

Fair warning, Hawk HP+ pads, while pretty damn effective for stopping, are not going to be quiet all the time. In fact, they are usually lightly to moderately noisy, and even louder at times. This is due to various ingredients that were added by Hawk to create that autocross and light track day pad. Hawk HPS and Performance Ceramic pads are usually quiet (depending on several factors, such as rotor surface condition, proper installation, proper bedding procedure, etc.), but the HP+ was never designed with reduced noise in mind.

Thanks Chris B, I expected them to be noisy but they screach so bad I may go deaf. The first two weeks the squealing was normal, not too loud. Then they got really really bad to the point that my ears would ring from pain. Yesterday I added more grease, the orginal grease was almost all gone. Hopefully this helps until I get the new rotors and I can resurface the pads as you explain.

Also, try using the Permatex Ceramic Extreme Brake Parts Lubricant (the purple stuff). It says on longer than anything else and is not effected by heat, even from typical track days (up to 1600°F!). Most anti-squeal compounds are toast the first time the temperature exceed their maximum.

This is EXACTLY the sound that my brakes give off, ESPECIALLY at lower speeds.
I'd be LIVID if a $300 worth of pads (front and back) sounded like that, especially when they advertise no noise (assuming they've been bedded properly).

Is that noise normal for HP+ pads? Because my problem is 100% as it sounds and as described the BMW owner in the video. I found that the rotos have grooves and I'm still waiting to swap them, my fingers are crossed that will solve my problem.

HP Plus pads are not advertised to be quiet. They are auto-cross / light track day pads that are streetable, but they do dust like hell and make some noise. Add to that the fact that grooved rotors themselves cause a significant increase in brake squeal, and you will have all the neighbors knowing exactly when you get home.

Update - I've been waiting before I post and since its been almost 2 weeks with virtually no break squeal I thinks its time to post an update. As I mentioned the noise was insanely loud. I took the car in to swap in Racing Brake rotors, I sanded the pad surface, and then went through the bed-in procedures. WOW, what a difference. The breaks barely make any noise now, just a ever so slight squeal which is hardly noticable. I'm very happy now, thanks for your help.

Brake bedding procedures.

I used this procedure on the Hawk Performance HP Plus pads (not the HPS) and it did the trick. They were squealing like crazy and had new rotors put on at the same times as the pads. I have dimpled/slotted rotors. I tried to use the Hawk bed in procedures three times with no avail. Use this one and you will be happy. Do it just like it says with no deviations!! No squeaks or any noises for that matter anymore!!

Bedding The Pads - (NEVER DRAG the brakes)
Note: Never “Bed” pads on rotors, which have not first been “Seasoned.” Always allow a substantial coast down zone when bedding pads that will allow you to safely drive the car to a stop in the event of fade.

Perform four-repeated light to medium stops, from 65 to 10 mph, to bring the rotors to temperature.
Perform three light stops in succession. Perform eight heavy stops, back to back, at a point just pending wheel lock, from 65 mph to about 5 mph.
Drive for ten minutes to create cooling airflow, without using the brakes if at all possible.

Just had the hawk HPS pads installed yesterday. Did not do it as much for performance, but to reduce brake dust. Very rainy day in Houston yesterday so bedding the pads was not possible. This morning, I went out and performed some hard stops.... 3 from 35mph to 5mph, then 3 from about 60mph to 5mph. Brakes did not squeal....until about 5 minutes later.

WOW! Where are the earplugs!

Looks like I need to go back out and try the method mentioned above. I'll report back tomorrow or so.

The Hawk pads are so unpredicatable. I put the Peformance Ceramic on my 2010 Camaro SS. I did the proper bed in procedure with brand new rotors and they squeal so loud it sounds like a bus stopping. It is extremely embarrasing. I put them on my 2011 Corvette Grand Sport Convertible. They squealed as soon as I put them on but after the bed in procedure they haven't made a noise since. And seriously on the Camaro, the brake dust from the ceramics is worse than stock. I'm going back to GM pads. I won't have to live with as much dust and I won't have to do multiple bed in procedures to get them to stop sounding like a bus stopping.

Wow I didn't realize how many others had this issue. Sounding like a bus coming to a stop is exactly spot on how they sound. I'm a little pissed at the unpredictability of the pads. If you guys remember my post starting this thread, I was not aware of the bedding process and drove around with the pads like that for a couple weeks before I bedded them. I was sure this was the cause of my problems. BUT my friend got some pads for his mustang and the same thing happened. He didn't bed them properly - he didn't bed them at all and his car doesn't squeek. I'm so pissed lol soon as I get my income tax I think I'm going back to stock pads. I'm going to look for a good set of slotted rotors while I'm at it.
