should my rotors be this color after break in
 

So I installed my ss lines, new rotors and hawk hp+ pads.
Got back from the break in run and this is what my rotors look like, they obviously got very hot. I have never used high performance pads like these before so not sure if rotors and pads are supposed to look like this.
Break in procedure went like so:

7 runs from between 30-40 to 10' moderate breaking

Pulled back in the driveway to adjust rear left caliper.

Went back out for 4 more 40 mph to 10 mph runs.

Then went on the high speed passes:

Did 7 runs from 75-90 mph to 15 with moderate to heavy pressure.

By the 3rd high speed run I could feel the brakes fading a tiny bit.

Drove home and parked the car without using brakes.


Hope the pads weren't dragging at all...

Upload a picture that works.

I had a problem with HP+ that ended up being a defective set of pads. Rotors got blue and had no wear pattern on them at all.

That's normal, usually mine are more blue.

thanks, i've never had a set of race pads before. this car stops on a dime, OH MY GOODNESS!! i can't believe how powerful these brakes are in conjunction with ss lines and motul fluid.

i'm glad i went ahead with the upgrade!!

Every set I have ever had has done that. Beats me.

lol, HP+ are nowhere near "race" pads.

how much do they squeal? I installed a set this week and FML, makes me want to keep a separate set of pure street pads instead of this dual-purpose-good-at-nothing shit

I've gone through 3 sets of HP+ and they all squeal like hell. Its pretty fucking unbearable, and apparently this last set wasn't bedded all the way before a track day. Ever since that track day these pads are an instant headache.

Well no squeal yet from these pads. I only have about 6 miles on them though so time will tell.

As it is they stop my car a whole heck of a lot better than the previous setup.

:doh: dual purpose, right...my bad

fuck, I can't even park in the underground garage anymore because that fucking squeal echos off the walls and sounds 10x lounder. ARGEGGGEAGG i'll start driving with ear protection :rofl:

I would gladly use shitty pads than ever use another set of these. For the track, who cares? But for around town....sheesh! I've had people and even cops come up to me in parking lots or at stop lights and ask me if my brakes were good enough to be driving on :laugh:

did you use any anti-squeal when installing?

I'm driving around town in my turbo car on DTC-60, lol.

You guys must be doing something really wrong. I've been through 3-4 sets of them and only had light squealing when coming to a stop....sometimes. They never really bothered me. When you guys have bedded the pads, did you get them to the point of fade?

Are you sure you're not thinking of HPS pads?

What's your opinion on doing this. They must squeal like crazy right? How much loss of braking ability do you see since they probably never get up to temp? I wouldn't go back to even a semi-race pad on the street, but I am curious. My hawk blacks squealed like crazy. However, it seemed like they stopped the car with a quickness :)

this is exactly how much squeal I have:

also, lol @ video title. I bedded them in properly. My friend has HP+ on his 99 and doesn't have these issues. I used a solid amount of anti-squeal, the CRC stuff.

I used the antisqueal putting them on, took them off and applied it lightly, took them off and applied it generously, ran without it, ran with it caked on, none of it helps. With this last set I have no doubts that I did not bed them in right, but the last 2 sets were bedded according to the instructions on the box. Still squealed.

I'm probably not running this pad again. It makes my fucking ears ring when I'm in an enclosed space, parking structure, etc. Also its higher pitched than that video. I actually thought it was the clips for the pads scratching the rotor or something. Didn't think pads could make such an awful sound.

Oh I'm sure. Though I did just put a set of those on my GF's MSM (better than stock, but not too aggressive).

that is most likely their problem. i did get mine to fade as mentioned in an earlier post. 6-8 runs from 90-15mph in quick succession will do that

I would have loved if my pads only sounded as bad as that video...

they were bedded properly, to the point they were smoking...


the rears never made noise acutally...but i somehow ruined my set when upgrading to the m-tune rear sport brackets...I warped one of the pads. I didn't want ot have ot replace them.

Made mine smoke too. And my pads are easily twice as loud as that video.

I think the part of the instructions that people don't pay much attention to is that important little part at the end. The instruction to not touch the pedal at all after your last hard stop. It means you coast to a stop using engine deceleration and sit on the roadside for a fucking hour and let it assume room temperature. Not "a couple of harmless little taps on the brake on the way back to my driveway". Not at all. No not none never nada.

I've put two sets on the rx7 and one on my buddy's G37S brakes and used no anti-squeal on them and they were quiet. On my buddy's car we ended up pacing back and forth on the side of an empty two lane road at dusk to keep the mosquitoes off of us while we waited an hour and fifteen minutes for the brakes to cool down to nearly ambient so we could drive back to his house. It was uncomfortable and inconvenient as hell but you can't touch the pedal again after your last panic stop until the brakes are cold.

The squealing is a high freq vibration. So if your not on the same caliper as someone else than it can be worse or better. I've noticed Brembo's and miata sport brakes squeal very little but 1.8/s2k brakes sound off at will.

To the Op: Wait until you put on some xr2/xp10/dtc60 and some slicks. I can feel my face move under breaking lol

Ive done some pretty aggressive pad installs, and Ive never had a problem with excessive squealing. Never done any full race pads on a street car, but some pretty aggressive "dual purpose pads," which is what we are talking about. Ive always just cleaned everything real nice, sprayed some disc brake quiet on the shims, replaced hardware, and bedded in properly.

Ive always got them hot without completely stopping then drove around without hitting the brakes. From what Im told you want to get hot then drive around so you get a good even amount of friction material deposited on the rotor, so I dont know if stopping and letting them cool would be the best, according to how Ive been taught to bed them in.

Put some carbotechs on a C6 and just hammered on them got them hot as piss and said screw it and then just drove around, stopped many times using the brakes, before I knew any better, while they were cooling and he never had problems with noise, so maybe its just luck.

The braking ability lacks, but cold race pads (DTC 60 and 70s included) chew up rotors like its a day job when they are cold. Did it once, wont do it again.
