Brakes shot at 23,000 miles, PICTURES

you got the good set LOL!
They seem to do well under highway/freeway conditions. I got 41k on mine before I got the brake wobble and I replaced the pads and rotors (slotted rotors). My pad were ok though and had some miles to go on them, and the rotors looked good, but I had a definite issue when I hit the brakes. After I changed the rotors and pads, I had mazda flush the brake fluid and inspect the front end and the brakees, no issues detected. I had no wobble after the pads/rotor replacement even prior to the fluid flush and replace.
OK nuru, what exactly should I be feeling when the pads/rotors start to "go south"? I have a very minimal squeak when backing out of my garage and that is the only time I hear anything from the braking system. Never have felt anything through the pedal either! From several of the postings, it sounds like the rotors have a real problem with them. Has Mazda every addressed the issues with a Tech Warning or recall?
I am amazed at the variety of experiences with the rotors on this vehicle. We have 35K miles on a 2010 (we drive it everywhere) and our rotors look fine. Actually had it at the dealership yesterday for an issue with the sunroof and they said brakes look fine. Other people have them go out at 15K miles and others last longer than 35K. I know that location and driving habits make a huge difference, but I am amazed at the amount of problems with the brakes.
The difference is a mystery. Were there bad batches or bad years or multiple brands used for OEM pads and rotors ? I just turned 66K miles and am on the original brakes and have no big issues. I can see that the fronts are getting thin, and I am getting some front vibration when braking hard, so I plan on replacing at least the front pads in a couple of months.

I have not seen whether or not Mazda has admitted a problem with its rotors? Anyone know who makes their rotors?
Some potential signs of braking maintenance required
If you are getting pulsating sensation when you apply the brakes, then you know it is time to at a minimum have your brakes inspected.
If you can see grooves in your rotors, then you know you need to do a brake job
If you get a progressively louder scratching sound (not a low groan/grind sound due to pad rotor compositions), If you can see grooves in your rotors, then you know you need to at a minimum have your brakes inspected.
If you become aware your stopping distances are getting longer and you have to push down harder on the petal, get it inspected.

Yes. The CX9's OE pads/rotors setup makes all sorts of noises when they are cold such as 1st drive everyday.
After they are warmed up, those go away. That does not means the pads are shot.
I am still on the original set. The last full-cycle inspection says "good" condition.
I will definitely go with Centric when it is time.

I cannot explain your bad luck but I am also in Boston and on the original rotors/pads/tires after 28,000 with no hint of a problem. You're not one of those crazy Boston drivers are you???
Can't be - Boston drivers never stop for anything,.. like red lights,.. pedestrians,.. ;-)
BAHAHAHAHAH! I'm a Boston drivers and my brakes still look as good as new. So I guess I don't brake for nobody ;-) Seriously speaking, my 9 is a family car and the brakes look new after about 7k miles. I brake like a sissy because I have my toddler and infant with me and do NOT wish to clean up vomit. I did break them in with some hard stops at the beginning and they don't pulsate or squeal at all. But I am also afraid that gentle braking may also lead to other issues like glazing on the rotors. Someone correct me if I am wrong.

I had my rotors replaced around 7,000 miles; the inside of the front rotor was grooved like a race track. Now, I'm up to 17,000 miles and the same issue is starting to happen again. I checked and felt the grooves starting to develop on the inside again.
I'm not hard on my brakes at all. I have an Accord with 35,000 on original rotors as well as an SC300 with 75,000. It maybe time to go aftermarket.

I've had issues with my 2012 CX9 brakes as well. Dealer put some kind of ceramics on at 30K but I didn't bed them. Is it advised to bed them now after they have already gone something like 10K miles?
Thx.
Thx.
Lol!!! I am not an aggressive driver at all. These factory rotors just plain suck @ss!!! I swapped out for Centric's and have not had a problem since.
