Default Need serious help fast with brake pad/rotor issue.

I just put new cross drilled slotted rotors on my 2002 Wrx today. I purchased the new rotors from a guy on E-bay and I picked up a new set of pads from the dealer today. So the pads are OEM pads.


I did everyhing today. Feel the I did it right. However I took the car out tonight and I hear a slight squeel while I am driving and then when I brake say from 30 to 0 I hear this wierd noise that seems to be coming from the rear but could be oth front and rear. Sounds almost like those locost bugs. Sounds like the holes in the rotors are making a wierd noise.

Is this normal? Will it go away? Is it just due to the fact that the rotors and the pads are brand new? I am worried about what the problem could be. Can somebody please help me.....

more than likely its just the pads vibrating slightly in the caliper....nothing major

go to your local auto parts store of your preference and pick up some brake goop...there's all different brands, all called different things.

bendix makes this blue ***** and some other companies make stuff too...it's normally blue and called brake quiet or something like that

take everything back apart and put it on the back of the pads where it comes in contact with the caliper..should solve your problem.

you get the squeal b/c the pads don't always fit 100% perfectly...especially on non-OEM brake pads.

But I used OEM brake pads. The only non OEM thing is the rotor. And what about the odd sound that it makes whne I do apply the brakes? Is that normal for cross drilled rotors or is it somehitng that will go away or will always be there?

Do the rotors have CD or Zn coating on the rotor surface? Are they those goldish colored type? That will squeal until it wears off.

OEM pads already have an anti-squeal pad on the back.


X-drilled rotors can squeal like that if the holes aren't drilled properly. As the rotor wears and the edges of the holes smooth it will go away. But expect more dust and worse wear.

Also Is there a reason why there are metal clips on all of the pads on the inner part of the caliper except for the left rear?

I noticed a small metal clip on one end of the pad that goes behind the rotor in the caliper. The front (both) and right rear had the metal clip but the left rear did not. Anybody know what that is all about?

Thank you for the advice. I will let it go for now and see is the sound goes away. I noticed not loss in breaking or any real change. Jsut that I come to a bit of a quick stop from 2MPH to 0. But I think that is because the rotors and pads are so brand new.


The other thing I already noticed was that the silver rotor is alread black because of the brake pad wear. I mean it was nice and silver when I put it on but now it looks all black. Is this going to go away too?

So they say about anti- squeal on OEM brake pads. Put more anti- squeal anyway preferrably the gel or tube type vs the spray ones.
Break them in as well

Ok I am going to try breakng them in for a week. But I noticed that it requires more force at the pedal to stop the car now. I hope this is just because the rotors need to be broken in. If not I have no idea what could be wrong.

It does seem like it takes more force to stop the car now.

Is it possiable that I have air in my brake lines? Are you supposed to bleed the lines when you change the pads? If so how do you do it?

Why? Please explain. Thanks

There is no reason to bleed from a pad change.

Yes most people are telling me that I should not have to bleed the lines but there are a few telling me that you need to bleed the lines after a pad change.


Can you guys please explain this to me. What should I do?
