Good point!

I hadn't considered rotors, either. My experience with loud brakes has only been limited to pads, maybe I should check my own out.

And, I would love to have the car chat with you; I was not looking at new cars vs new cars, I was looking at performance cars vs performance cars (after all, if I'm going to buy a car for its performance, I'm not likely to buy a brand new one), but I don't think this particular thread is the place, as there's been enough off topic play in this one.

hey look - its another RX8 owner who thought they were buying a nice looking Honda Accord as a daily driver....

A dose of reality for you...

A) You bought a sports car as a daily driver. A sports car gets bad gas mileage at the expense of power. It has short gearing at the expense of cruising RPMs and gas mileage. It has performance biased brakes that deliver great stopping power at the expense of noise. It has a rougher riding suspension then a couch on wheels. The steering feel is tuned to feel alive and not isolated like a Camry.

B) You bought a rotary powered car. Expect a gas pig. Expect it to consume oil. Expect to have to deal with the character flaws like cold start flooding. Expect it to go like hell and sound good doing it.


If A or B offend you - either live with it or sell the damn car because its clearly not the "daily driver" of your dreams. I don't care if your a guy or girl - you bought what you bought... and i appreciate any female car enthusiast for the record

C) Look at any published 0-70mph or 0-60mph stopping distances - the few cars that stop shorter have the name of Porsche and Ferrari on the trunk and none from Japan. You have amazing brakes, stop bitching about them.

D) the Dealer is never going to solve your squealing "problem" no matter how many time you go back to complain. Mazda has not reformulated a weak stopping, squeal free pad that belongs on an Accord - and I for one commend them on that. You can take it back all you want, the squeal will return and I'll thank you for contributing to the big old black dot of death that appears in the Consumer Reports reliability study under "brakes"... take it back for gas mileage too while your at it so I can thank you for the black dot under "engine" and my resale value being in the *******. Maybe you can go to Pepboys and buy a set of their worst stopping pads and you'll be happy.

E) The classic "The car costs $30k... it should be created as perfectly as god could himself" story. Sorry, a $30k car today is not special. Maybe you should read the $77,000 Audi RS4 review from Autoweek - it has aggrssive brakes that they noted that they squeal like crazy.. and they loved it for that.


F) Go out, drive the car like its intended to be driven, enjoy its strengths, forgive its perceived weaknesses...

r0tor, not to debunk everything you just said about me, but:

Keep on flaming, you're just going to end up getting this potentially helpful thread closed.

webgrl

There is a way to make a point without being a dick. I am only here to learn more about my car, and seeing as you seem to have all the answers, I thought perhaps you could have shared some with me without trying to make me feel like **** for "buying a sports car."

I wanted a sports car, and I bought one. There is a learning curve here, and you should recognize that. I'm sure you didn't know everything about your very first sports car, and I bet you didn't appreciate the ******** that liked to point out how little you knew.

Seems as though you haven't always been happy with all the sounds your rx8 makes either:

yea, and it still is a rattle trap and i've never complained to the dealer about it... fixed a few things myself and lived with the rest

what do you expect from a 3 year old Mazda?

cavemancan

Just send me a PM sometime and I will answer what I can. If I don't have the answer I am sure I can point you in the right direction.


Back on topic PAH LEASE!

yes you can put slotted or dilled rotors on and they will keep the brake pad surface scuffed up enough to prevent some squealing (since the squeal is really caused by the pad surface glazing over)... you just go through pads quicker then however and the rotors themselves are argueably more succeptable to cracking

cavemancan

I agree with the pads going quicker...definately but from what I've noticed so far its only slighly using the pads quicker.

Cracking? How so? My understanding is the rotor disc would have to be placed under extreme temperatures (like 24 hr endurance race) and then cooled very quickly. Under that type of race I would never use a drilled and slotted rotor but then again I would not likely be in that type of endurance race.

It may even happen in a 4 hour endurance race but if I were ever to be in one (4hr or 24hr) I would probably be using the stock rotors or Racing Brake Solid 2pc rotors. Cracking I think would only happen during those extreme instances.

I picked the slotted and drilled rotors primarily because I am autocrossing and I needed the lightest weight rotor I could find while still having great brake response/feel etc.

Not trying to contradict you in any way...You may have more insight in this than I and I appreciate a good debate/conversation.

Read this...and some other things from this site.


Drilling causes induced stress...and makes the rotors weaker...therefore more likely to crack.

Everything is a tradeoff........good pads usually are much noisier than poor ones!

They were designed to stop the car...... and work as well as a Porche Turbo

What do you expect?

sm4k

I still think the most cost effective and likely to work solution is to pull the shims off and give 'em a good cleanin/greasin'. It's been my experience that my consistant brake squeal has been when there's dust between the shims and the pad/brake, or if the shim is somehow loose.

I'm just trying to think outside the box, here. :P

itsallaboutgary

thats exactly the problem. read post #8

and don't forget to use some kind of Product that will decrease the amount of dirt that gets in there and cause squeaking again. like CRC brake quiet =)

cavemancan

True this does get rid of the noise but it eventually comes back once the pads get dirty again.

cavemancan

Very true but I guess what I meant to say was that for my application my rotors are not likely to crack.

This is true...the kicker is our cars only cost a fraction of a Porche.

rovic

I have an '04 and my brakes are noisy too. I think I have <50% pad and my warranty is about to expire.

Can one use the noise as an excuse to get new pads for free this late in the game?

kors-jan

This is my response to the original question in post #1:

There is a Technical Service Bulletin (TSB) regarding the OEM brakes. Here's a link to Rosenthal Arlington Mazda website about the squeal:

http://www.mstore2000.com/PDF_Files/04-001-06-1568.pdf

My front brakes squealed LOUD at 14K miles. I took the TSB to my local Mazda dealer and they replaced the pads and hardware at no cost to me. No more squeal, and it's been almost a 1000 miles since then.

Oh, they may say something like the TSB is only good for cars with less than 12K miles or 12 months. But if you respond nicely/firmly that the pads on a $30,000 car should last longer (like I did), they probably will do the fix -- especially if you stand there waving a copy of the TSB as you talk.

When these are worn and need to be replaced (and I have to pay for it), I probably will install the the Hawk ceramic pads. But for now, this free fix using the TSB warranty was great.

I know others in this site have written a lot about "bedding" your brakes or cleaning them out of brake dust -- and given specific DIY instructions. You should search for these posts and read them to see if they apply to you and try them.

Hope all this helps. Report back on how it goes for you -- especially if you try the Mazda Shop again.

RX813en

I got mine replaced with cheap (softer) pads and the squeal went away. Of course, then there was a lot of brake dust on my fron wheel. So now im going to try the ceramic ones and see if they work.

Patrisa

Brakes never squeaked until i had front rotors and pads replaced at about 45K miles, gone back to dealer twice to have them "deglazed" still same problem. It's loud enough to wake the dead. In regard to a comment about "stop bringing my resale value down"...I'm sure you are as unhappy as the rest of us that this car has so little resale value. The RX8 does not live up to the standards of the rest of the Mazda line of autos. I wish I never bought mine..had engine replaced, burning thru tires, always adding oil, I seem to always be at the dealer. I've had other performance cars and I must say, wish I still had them.

Same here. Replaced front/rear with cross drilled/slotted rotors from RacingBrake and not a single squeak.
