Default Odd braking noise

When coming to a stop i can here what sounds like a creaking sound while braking but it is not constant, it is rotational (if that makes sense). Meaning its happening at a certain point everytime the wheels rolls. I know this is not a very good description but does this sound familiar to anyone?

Any chance your rotors are warped? Do you feel any throbbing in your brake pedal or just the noise?

Most of the time people think "warped rotors", it's actually just uneven distribution of pad material. This often happens when a person does some performance driving, enough to get the rotors fairly hot, then they stop and leave the brakes on for a while. This can cause some of the pad material to stick to the rotor, leaving a somewhat raised spot that you can't see, but it's easy to feel. No idea if that's the case for the OP or not, just pointing out the possibility.

Ya, that's one of the big keys of new pad/rotor break-in. Don't come to a complete stop with the brakes applied. I can see how that would do it.

But I would think that with one good stop it should clear that excess material off of there? No?

No, "one good stop" isn't always enough because it usually doesn't generate enough heat, but you're on the right track. If I had the issue the OP stated, I'd try something similar to the usual new brake break-in process. I'd suggest doing 3 to 4 rapid stops, going from 60mph to 5mph, one right after the other so that they don't have time to cool completely in between. That should be adequate to smooth the surface as much as possible, such that the problem should go away, and if it doesn't then I'd suspect there's a larger issue.

i had a weird creaking when braking similar to what you're describing coming from my rear left wheel and it turned out to be the wheel bearing.

Yea I think a warped rotor or wheel bearing would be to blame. I haven't been driving fast or braking hard so I dought its uneven distribution of pad material, although I wish it was but I have been hearing this for over a week now. If it is a rotor I won't be all that ____ed cuz I would like some good lookin rotors to replace my rusty ___ ones.

you can doubt what was said earlier, you can do anything you like.
If you want the real advice, then you might want to listen. Seriously.

The rotor can develop "high spots" like it was mentioned by Nodsetse, because of the oem braking material leaving uneven deposits. I've had the same exact issue before and a couple of good hard brakings would solve it over time, it doesn't solve itself in one day though. The rotors are not warped and you're wasting your time getting them "turned". They'll charge you as much as a brand new set of rotors and if you want to waste your money go ahead, because the issue will just come right back! Plus you'll have less material on the rotor.

Nodsetse is 100% correct in that high spots can form. You mentioned rusty rotors, then you definitely are not getting them hot enough to burn stuff off, sounds like the car sits for awhile, then you don't heat up the brakes enough, so you never burn off the rust combined with the oem pads nature of not completely clearing the rotor is what's leading to your noise.

wheel bearings can go bad but by the time you hear them making noise, YOU ARE FEELING IT AS WELL (vibration).

what you need to do is apply the brakes harder without of course causing an accident. drive the brakes harder for a couple days I will bet you see the noise begin to lessen and disappear. you at least should try it, it's free!

I will definately try it, i was only doubting it because it has been a solid week now but it can't hurt to try.

So I went to get an oil change and had the dealership take a look at my brakes. They claim that the rear brake pads are frozen and I need new rotors. I am not exactly sure what frozen pads are, can someone fill me in. (I'm on the original rotors with 70k). Then they threw down some outrageous prices so I just told them to give my car back, I'd rather purchase rotors of my choice and see if my buddy will give me a hand installing.

frozen usually means the caliper is stuck causing the pads to wear against the rotor.
usually brake service should've been done during the 70k mile period to lube the caliper sliding pins. That's usually what causes the frozen caliper from what I've seen. It's easy to remove the sliding pins and lube them up. Sounds like that wasn't done ever. should be every 30k at the most.

what did they dealer want to replace? and what price were they asking?
