Final review (luckily it was dry and there was a long stop and go traffic jam): Noise = gone.
I'll try to take a pic, or just find a pic of a rotor and highlight the area. There was a fair amount of rust. The newspaper I put down had a pretty good amount for each wheel. I just had my rotors resurfaced last year. I think it has something to do with how much less I've been using my car these days with carpooling etc. Sits for a few days at a time...
EDIT -
Here is a picture of the back side of a rotor (not mine). I highlighted the area where rust had formed and was scraped/sanded off.

Wow nice job...i wonder if i can get my dealer to do this for me (boom07)
i mean i've had my front bushings and had my front struts replaced b/c of the dealer's diagnosis of this driver-side popping...i was going to bring her in for the 3rd time to address this problem.
you indicated its rust related, would that mean ur fix is temporary (i.e. scrapping off the rust) as rust will most likely reappear? Would there be a more permanent fix? I mean i'd be willing to buy/replace parts (simply replacing the rotor?) to avoid this again.
Again (deadhorse
good job

Keep in mind, if you've got popping when turning the wheels etc, this could be a ball joint or CV joint. But if its just when coming to a stop, its likely the problem. This was pretty much a temporary fix to see if it stopped the problem, and it did. We'll see how long it lasts. He mentioned next time I visit we'll replace the bushings and take the rotors off and grind that part down to get rid of all rust. I would imagine a high temperature anti-rust paint would work well on a new set of rotors (on that small part) to prevent rust from ever occuring.

Nope the popping only happens when coming to a stop when im on the brakes...i actually can make it pop on command (boom07) by getting off and on the brakes at certain slow speeds. Well any solution is better than no solution, your fix sounds good to me. Will be doing this when i switch over to the winter shoes and will update further if anything unexpected happens.

Update on this thread. The popping came back a few weeks later. Sure enough, rust started forming again. Unfortunately our pads don't scrub the entire surface area of the rotor, and if you're warped at all, it seems to escalate the problem.
Regardless, we scraped rust off and still had some popping. I magically got the car and wheels into a position where when completely stopped (E-brake on) I was able to reproduce it simply by placing my foot on the brakes. We touched the pad a bit while braking with a long screwdriver and it stopped.
Basically, I'm either going to need some kind of brake hardware kit that replaces some caliper components, or will need to buy new calipers. Does anyone know if there is some kind of brake repair/hardware kit available at the dealer that replaces the bushing that comes into contact with the slide etc?
Thanks,
Chris

This sounds like what I need (from mazdastuff.com): GAYR-33-26Z SEAL & BOOT KIT

Interesting, it seems to be coming from my passenger side the most as well. Anyhow, it very well could be the piston sticking as well. But I guess I'm starting cheap and working my way up. I need new front rotors anyhow since they are warped, and my front pads could probably use a swap. That part I listed above seems to include new seals and what not for the piston as well. Basically it seems to include everything to do maintenance on an existing caliper. Hopefully it will work. $40 a side from mazdastuff. I imagine a caliper is more...

I have it too...not real bad yet, but its noticable...only on the passenger side...
I cannot get it to happen at all when it is raining or wet out...My rotors have been serviced twice, but they need replaced soon anyway...
One thing that I was wondering if you guys have too, is the uneven braking...When I use light brake pressure the car sort of lunges slightly...when I get below 10mph, it feels like I am pumping the brake pedal even though I am holding it in the same position...
There is lots and lots of rust on my rotors...but Doomer you are saying it could be the calipers? as in the piston is starting to seize in the caliper? either way that doesn't sound safe...I need to take care of this...I am going to simply replace my rotors (either way, that needs to be done anyway)...if I am still having issues (that will definately cure the lunging thing) I guess I will have to look into caliper rebuilds too...and that is far from cheap...

my update:
when the car is off, I notice a creaking sound coming from inside the brake booster cylinder...it sounds like a linkage needing greased, but I have never gotten inside of one of those...it also looks like you have to remove the master cylinder in order to do it, so screw that noise...
its not bad, and it only does it without the engine running (so off vacuum)...the clunk is lessening however...and I am almost positive mine is pad/rotor related...the ride front pad is nearly 1/4 lower in pad depth than left front...and the front right has pad material glazed onto it because I didn't change the pads in time on the last change...and that is the side that the noise is coming from...
I will let you know, I should be changing pads and rotors again within the month...

Bump!
I know this is an old thread, but I have the same "symptoms" on my MP3. I guess I will try to take apart the passenger brake and see what is going on. Did anyone find a solution to this problem?

Finally ... I'm not alone !
I get this repeating popping/clunking/scraping noise only when I break lightly and at low speeds while coming to a stop. This is the ONLY time the noise happens. If it rains, the noise goes away. If I brake hard, or don't use the brakes, there's no noise.
I've been to mechanics and nobody was able to figure it out for sure (although they had some theories like CV joints, etc ... but I don't think they make sense).
I've been searching everywhere on the internet for an answer, and I was beginning to think that I'm the only one with this problem until I found this thread ...
If you had this problem and found the cure, please share your findings. Was it the rust on the rotors as some said here? Calipers?

I think fixed the problem! After taking off the rotor I saw there was a bunch of rust on the wheel hub. The person that replaced my brakes (before the winter) was an idiot and didn't bother to clean the area. I used a chisel type thing and a wire brush to scrape it down to clean metal. After that everything is good as new. In the end the problem was the rust causing the rotor to be seated crooked and the caliper would move side to side because of it causing the noise. I checked the other side and it had no rust, but then again it didn't make noises on that one in the first place.

Right after I had the brakes replaced, it seemed something was not right. At first I thought it was because of the breaks needing to bed in. I heard it a few times over the last couple months but nothing major. Since it finally got warmer a couple weeks ago I was able to open the windows while driving and that is when I realized something was not right.
re: brake problem
Yea, I'm in the same position as well. I'm goign to try this next. I'm doing a step-by-step process to eliminate this, instead of having a service place over charge me for it. Yes, I did buy the vehicle as is about 3 weeks ago and I told them to fix it, but they didn't. My own fault I guess, but I will overcome this and I will fix this! I hope everyone wh oposted on here sooo far has had no problems. I will have an update in the forum under pop, clank, kock update: We will get to the bottom of this, oh yes we will! Oh and I hate it when I'm slowing down to a stop and people are looking ay my nice mazda, but hear an awful sound!
