I have a 2002 Suzuki Aerio GS. I am a little over 81,300 miles.
When I first start driving, and I brake my car sounds normal. After I've been driving my car for a few minutes, when I brake my car will make this strange indescribable sound, that comes from the front drivers side. It's never the same amount of time, sometimes it takes longer to start making the noise. It happens when I brake normal, like when I'm easing in to a stop and gets louder as my foot pushes the pedal down to a complete stop. If I stop very slowly, or pump the brakes, it won't make the sound. It seems to happen more when I've been driving at higher speeds and then brake, not slamming on the brakes, just easing in to the stop normally.
The noise is this loud creaking sort of sound. I want to say it's a hollow sound, but I don't know if that makes sense. I guess there is kind of a grinding sound, but my brakes are perfectly fine. My uncle does my car repairs and he couldn't figure out what the sound is, his theory is that my tires are worn uneven and that is causing the sound.
I did buy cheap brakes, the cheapest available for my car, the sound didn't start until a few months after my brakes were put on and the brakes were put on right before my inspection in which I had to replace 1 tire. I was sold defective tires by my local auto shop, and three have gone flat on me, so all four of my tires have been bought at different times, so they are all worn unevenly.
Also, the stem valve on the back drivers side tire is bad, I need to get it replaced. I think I'm going to do that tomorrow after work and get my tires rotated and balanced.
If you need any other information, please let me know. I've searched the internet forever and can't find anything. This has been going on for probably 5-6 months now, but my uncle said everything is in perfect condition and I shouldn't be worried. He said my brakes are fine, but I could try buying a better brand and see if that helps at all.

Yeh - tires are a maybe but also pads (some) have a noise maker as a wear sensor and some might have been bent causing noise before wear out. Most sensors of the type make noise when NOT braking and shut up while braking but worth a check.
Here's a generic pic of what some look like....
Check if that's touching too early for the wear,

I had noise when braking hard. It was due to bad motor mounts which let the engine shift forward and put pressure on front bearings. Had to replace motor mounts and one wheel bearing assembly. Expensive! $1000

I don't know who gave you that story but that's nonsense. The motor isn't going anywhere because the brakes were applied. There is no relationship between the two. There will be a weight transfer from braking but it has nothing to do with motor mounts.

Front wheel drive? I have had many experiences with similar problems(unknown noise) in front ends and found many of the problems were inner cv joints in the front axles. They are pretty hard to diagnose but as best educated guess proved, new axle fixed the noises.

In the past, brake pad friction material relied heavily on asbestos. Unfortunately, asbestos tended to give asbestos workers and brake mechanics lung cancer, so the industry has almost completely changed over to less dangerous alternatives. Kevlar is one material that’s seen a lot of use, but it tends to be dusty. Improved brake performance is more important nowadays because of increased safety requirements and equipment—and the extra road-hugging weight that comes along with these.

Doesn't mean your brake pads are fine. Quality of brake pads now are junk. You still may need to replace it.
