this snapping sound does it sound like a rough spot in a rotor when your under light braking at low speed cause i have one that sounds like that and it kinda has a binding sound to it hell i'm gonna try the fix this weekend it can only help

not at all the snapping nosie the wheel physically hopping on and off the hub, it has notthing to do if your braking or not.

The winter wheels must change the resonant frequency of the wheel/brake system thus damping the squeal. The winter wheels must clamp the brake disc better than the stock wheel. Come to think of it, the popping sound seems related and implies that the wheel isn't securely clamped to the disc. And by securely clamped I don't mean the lug nuts aren't tight enough. I mean the mating surfaces between the wheel, disc and hub aren't true to each other which results in not enough friction to keep the pieces from sliding relative to one another. Since the winter wheels fix the problem, the solution must be with the stock wheel (not machined flat enough?). Note: Changing to a ceramic pad is supposed to get rid of squeal.

could it have anything to do with that nylon gasket that is on the stock wheels?

When I went to my dealer to get the brake squeal fixed, they said it was because my rims were dirty and it was dust. I told them that I knew it was a common problem with rx8's and that there was suppossed to be something they could do. The guy said he would check on it, and when I came back later that day he said the only thing Mazda said was that he was allowed to change brake pads on 04's only. There was no fix for the 05 model, so he cleaned my breaks instead, which made the squeal go away...for about two hours. I left the dealership, washed my car and my rims. About an hour after I washed it, squeel all over again.

Well temp. is huge when it deals with resonance. Being a musician, i noticed that the temp might have something to do with the resonance in the brake disks. The constantly cooler air keeps the metal cooler and thus for resonance to occur it has to happen at a different frequency then when the disks are much hotter.

Had new brake pads installed, problem came right back. Nowdays I get a very high pitched hiss in my front brakes after doing a lot of braking during high performance driving. What seems to help is to apply some Brakleen followed immediately by some hard braking. Helps to shut up the brakes for a bit so that it's not happening every single time I brake. But fact of the matter is, looks like squealing with the OEM brakes is a terminal problem with RX-8s.

Did everyone at least bed-in their brakes when they got the new pads/shims? THAT makes a huge difference!

I'm going to replace my front brake pads but I've never done this before. I chose a CRC spray over the red squeeze tube. Why do you say don't use the spray?

RotaryRider, I know this is a bit late, but just in case you're still dealing with the issue. I have an early 05 and my vin was within the range. Print this out and take it to the dealer if your vin is within the range.

I haven't had any squealing at all since I had the TSB done.

I've heard that the spray stuff doesn't work nearly as well as the tube, but thats just somones opinon im voiceboxing. BTW you could always just get a free set of pads from Mazda that don't squeek.......

But my brakes never squeaked. I just want to replace front pads because I'm at 50,000 miles on my original ones. I just want to make sure my new pads don't squeak. So I don't think i'm eligible for the free pads.
