Strange creaking noise from brakes

[03GMCYukonXL]

New brake pads, new rotors, new calipers, parking brakes removed. It was doing this before the brake work. Still doing it. No brakes were applied during the video.

calipers tend to spread some times. so the pads are not sitting flush to the rotor, so the pad could be cocked a bit and dragging.

if your not finding anything out of true, take the caliper off shim some wood between the pads hang it out the way and put the wheel back on and see if the sound is still there. dont drive it, just like you are in the vid. wood in-between the pads keeps them from opening up the pistons to far and blowing them out. then you got a mess. you will have to push the pistons back in to re install the caliper if you touched the brakes. but if you need to at least you can stop.

It's brand spanking new calipers and rotors and pads though. Noise was there before replacement too. Could this be a wheel bearing?

That's possible...

Jack the car, turn the wheel and feel if there is resistance and you can put something next to the wheel, to look if the wheel is out of center or wobble.

And wiggle the wheel to feel if there is play in the wheel bearing.

 

[03GMCYukonXL]

I didn't feel much play in the bearing but it did not make the noise while jacked up. It only makes it under weight. That tells me it's probably the bearing. Also there is a bit if resistance

 

[nonickatall]

In the begining of a failure wheel bearings mostly only make noise under weight and feel good when turned on jack...

So it is likely that you have a problem with the bearing...

Defnitely sounds like a bearing but the resonant frequency does not sound like it is traveling through steel. Its sounds like it is traveling through aluminum. Check your U joints.

The tire is turning well less than a quarter turn everytime it squeaks. That leads me to believe it is not the axle bearing since they typically get pitted in a certain spot or area and that would require a complete revolution of the tire(axle) to make the squeak. Not a fraction of complete wheel rotation.

Good point..

What are U joints?

What are U joints?

Universal Joints. Connect the rear driveshaft to the transmission yoke at the front and the differential pinion yoke at the rear. Most driveshafts are made of aluminum now.

 

[nonickatall]

Ah, ok.. Thank you...

I didn't know the English word for them. We call them "Kardan Gelenk" in German, thought you call them cardan shaft...

Most(U.S.) call them U joints or Universal joints. And the driveshaft is typically called a Propeller shaft in the books.

That is something sometimes very difficult for foreigners, like me, when you speak a language not like native speakers and then you try write about technical issues and looking for words and try to translate that and get totally wrong words.

That remind me on a funny scene that I had once with the foreigner in Germany wich wanted to tell me that she knew a woman, which was going for a surgery to remove a rib, to get a "bee hip".
And I asked her. A bee hip?
Until I came to the idea that she meant a "wasp waist".

I assume by U joints you mean the drive shaft joints? I will check them but I assure you that the noise is coming from that hub somewhere. It a lot more obvious when you're there than it is through video. But hey what can it hurt for new bearings anyways right? I'll change them and if the sound persists, I'll update this thread.

Are you sure that the rotor isn't rubbing the splash shield? Were the splash shields in good shape?

but as @rockola1971 rightly pointed out, this noise is not once per revolution but about every quarter of a revolution. That doesn't really go with splash shields.

Also, it doesn't do it when the car is jacked up. It's only under load. Splash shields are pitted and rusty but not misshapen. Like in said, I'll change the bearings anyways because it's can't hurt.

Is hub clean so the rotor sits flush? No rust jacking on the hub?

It don't sound like a rotor touching something and the noise is every quarter rotation. That don't fit to problems with rotor.

And when it is only under load, I would say: wheel bearing.. When rotors make noise, they do it without load as well, or during brake. But rarely only unter load of the wheel... In my humble experience...

Don't you think?
