I've read a couple of posts about rotor wear and maybe some grooving. Here are some pics of my discs that I took today.

Front Left

Front Right

Rear Left

Rear Right

The front left feels like a small ridge and not a groove, I'm guessing the pad is not completely level across the entire face.

I'm gonna take it back to the dealer and have them change the pad on the front left. Hopefully that will even out the wear.

I doubt they'll change the brakes on just one wheel instead of both wheels.

Also, the unevenly worn rotor needs to be machined for the new pads to seat properly. Otherwise you can be looking at very expensive repairs down the road.

One way that grooving happens is something gets lodged between the rotor and the pad.

Another one is if the pad was shifted (say in shipping) and didnt seat correctly from the very beginning.

It needs to be addressed quickly. They wont turn the rotors since its a new car. I would make sure they replace then as a set.

Mine are also doing this after only 250 KM's - BEWARE all, mines going back and it better be for new routers / pads.

i wonder who else this is happening to, imma check it first thing tomorrow morning...is this under warranty?

 

[vaBooM]

Yes. Our warranty covers everything except general maintainence.

Yes. Our warranty covers everything except general maintainence.

I thought brakes are considered general maintanence. But I do think most manufacturers covers brakes for the first 12 months/12,000 miles. Not sure about Mazda.

 

[vaBooM]

I was told "general maintainence" is oil changes and alignments. Brakes may not be after, say, 10k miles.

But since people are having small problems with less than that, Im sure they will replace them free of charge.

Good luck on getting free brake service. Most dealers will tell you that brakes and rotors are wear and tear items and are not covered under any sort of warranty, even if it is blatantly obvious that there was a manufacturing issue with one or more of the parts, such as is the case when grooves develop on a car with only 1000 miles.

i am replacing the rotors and pads and brake lines just for the hell of it when my first set of brake pads go out.

 

[funkyfreshmonke]

yea my dad wants to get different brakes too...im thinking brembo .... *snickers*

Ouch

Yeah, that does not look healthy. My front rotors are completely smooth. The rears have raised lines which are supposed to be there.

The dealership will cover EVERYTHING for the first 20, 000kms/1st year whichever comes first. Take it back ASAP before they blame you for something like abusing the breaks or whatever dumb excuses they come up with.

 

[chibisak]

As experience, Brake and Rotor are not covered by the Dealer
but u might get luck in there

I'm stopping by my dealer on the way home after work. I'll keep you guys informed. FYI, my dealer is the same one that hosts the website. www.mazdastuff.com

Why are the rears supposed to have raised lines and, if you don't mind me asking, wheer did you get your information?
thanks

Update-
I dropped by the dealer today and the service manager had a look at my rear routers - mine were mildly grooved and he now wants the car back in tomorrow to take the brakes apart. He says it doesn't look right and feels (from his 1st look) that the pads may have shifted. I'll post again tomorrow

Final Update - Mazda is replacing the rear routors and pads. They found a lot of road sludge behind the calipers that was causing rusting / grooving and pitting - rears only for whatever reason. This may be a problem that will impact others, especially those in snow climates where a lot of dirt is dropped on the road. They will be passing this on to Mazda corp as a Heads Up.

I am having the same problem with my rears. I took it by the dealer on Saturday and the took a quick look. They made an apointment for this saturday and they are going to take it apart and look at it. The fronts are smooth, but the rears are slightly grooved. I only have about 800 miles on the car.

After the quick look, the shop foreman thought that maybe the hand break was too tight.

You can tell that something isn't right though. There is a large amount of break dust only on the rears.

I'll let everyone know what the verdict is when I get the car back next week.

 

[psymn]

I have had a similar problem with my car. I noticed after one week that the rear wheels had much more brake dust than normal.

I took it in and they said that there was a service bulletin on the problem and that it would be fixed in a day. The next day they said that the rotors were too worn and had to be replaced, and they said the I had driven with the handbrake engaged. I told them no, that I had in fact never used the handbrake since I have an automatic.

The dealer said that they would "make an exception" replace the rotors under warranty. This was not the dealer where i bought my car, and I think that they just wanted to me to take it somewhere else.

There was a similar problem w/the rear discs on the P5 when they came out... Migth wanna do a search on the NHTSA/Alldata sites...
