Noise from newly replaced rear pads and rotors
I replaced my rear pads and rotors and now I have a constant noise. I am almost positive that it is the parking brake. Sounds the same when I apply the brakes while driving.
I took it all apart again to adjust the parking brake. I backed off the adjustment all the way, put it back together, and still have the noise. Has anyone else had this problem with aftermarket rotors? Any thing else I can try?
I have also developed a high pitched squeek when I come to a stop. Any way to get rid of that?
Thanks

That squeal is the pads vibrating against the piston that forces it against the rotors as you press on the brake. The remedy is at your local auto parts store , I use brake quiet. But the clerk there can direct you to the product that they carry, you gotta take them apart again, apply the stuff too the rear of the pads.And then reassemble i'm guessing that will also take care of the driving noise as well.
What is brake quiet, some kind of grease? I am almost positive that the constant noise is from the parking brake. The sound it makes is more of a scrape, and sounds kind of hollow. I jacked the back end up and turned the tires. I can feel and hear resistance.
Thanks for the help

Brake quiet is more of a silicon rubber compound. It goes on the back (metal) side of the pads, NOT on the working face against the rotor. Question, when you took your calipers off, did you compress the piston before putting it back together? If you did, and you have that rubbing sound, be sure all the parts are lined up and not crooked. Pads will rub some naturally, but sounds like yours are too tight.
If you got economy pads, you might have to live with the noise. Most of them are just that way.

Have you checked your caliper sliders are free?
Also that your caliper piston is not "dragging"?
Both of these problems can cause the noise your describing.
Pads are meant to "float" above the rotor. If the caliper pins or caliper pistons are sticking due to dirt/lack of grease in the caliper slider pin boots/a split in the rubber gator around the caliper piston and rust has now formed.
All cause sticking.
Hope this helps?

I compressed the piston in all the way so it was flush with the body of the caliper. Everything went back together real easy.
To me the noise sounds like a high spot on the ID of the rotor hitting the parking brake pads. Its a constant off on off on scrape sound.
With the back end jacked up I can wiggle the tire back and forth real easy, but when I try to do a complete rotation is when it catches something.

did you grease the anti-rattle clips?
you could get the insides turned
or
i'd take the rotors back seems like they could be warped

Hmmm.
If the caliper pistons are OK are the sliders free. They are the rubber booted covered pins the bolts slide through.
The bolts usually always slide, but does the whole sleeve that they slide through move through the caliper as well?
Pinch either side of the rubber boot and try to slide the whole thing through the locating hole in the caliper.
If it's stuck are very difficult to move, the sliders are stuckand need freeing off.

I did the rear brakes over the weekend and now have the same issue.
