Default Are power slot rotors and hawk hpplus pads suppose to squeak

Hi,
I just changed new powerslot rotors and hp plus pads for my sti. It brakes great. However, when coming to a slow stop, the rears sqeak very loud that it hurts my ears if the windows were down. However, at high speeds stopping it is very quiet. My installer said it is normal for the loud sqeak and when he sees me he may be able to do something to lessen the sqeak. I was wondering if this is normal with these rotors and pads? I mean I do not want to look like an idiot every time I come to a stop because it is pretty annoying. Please advise
thanks

Fixed it for you -

I pretty much say it all the time..

There is no free lunch in brakes - Brembo's are noisy - shims/goo/CRC are band-aids that can help - but are unlikely to eliminate the problem. And HP+ pads are about as much as you can ask for in a streetable pad - you will miss the braking response if you go back to a pure street pad. If you don't then you shouldn't have bought them.

In my FHI 4 pots the HP+ are not that noisy - just an occasional squeak at slow speeds - light pedal. I do not know why people make so much issue of the noise unless I am just lucky to have quietish brakes.

Have you bedded them in? Did you re-use the factory shims (I didn't but...)

my tech recommended it and he is really good. He says hp+ are great pads even for street use and they brake so well but the noise is unbearable. He said he wants me to bring in the car and try to do something to the shims and calipers to reduce it a bit but it might not got away/

Do a track day and they will be fine. They tend to make a crap load of noise until they get really hot a few times.

They do stop squeaking if you get them into their temperature range, but after a couple of weeks of tooling around town, they start squeaking again. HP+ is a great pad, but not if noise and dust really bug you.

After a while you may get used to the noise and actually think it's cool.

I've gone through a set over the past 7 months. They were really loud at first- lots of noise. Now that they've been heat cycled to oblivion, they're nice and quiet Time for a new set.

My tech, sorta fixed the noise. HE put some type of stuff in between the shims like a lube of some sort and they are quiet. He also put a sheet of aluminum padding in between each pad. HE said the hp plus pads are great at braking but the scarafice is noise. I get loud squeak high pitched only when the car is slowing to a stop with light pedal braking. If I brake hard on the highway or road no noise.
I guess these pads are just aggressive.

The silicone brake grease he put in there will burn off. You will have loud pads again. HP+ are loud. No way around it.
