Brake pads?

Hi,
Just wondering when you guys replaced your brake pads. I have 35000 miles on my RX-8. About 2 months ago when I brought my car to the Mazda dealership for something else, they told me that I would need new brake pads soon, though they didn't tell me how soon.
Also, how much did it cost to replace the pads?
Thanks.
Ray

Wow, no response yet. NON synthetic cause synthetic hardens the apex points on the rotors, eventually to cause them to shatter. But from there, Mazda says 5-20 in the US, but there's a huge argument with some folks swearing, with good reason, to use 5-30. What region of the US, northeast, southeast,....? Hotter regions appear to have more problems with damage to the rotors with the thin 5-20 oil.
5-30 is to thick and blows by into the CAT seemingly causing the CAT to fail sooner the EPA rules allow (80K miles), where as 5-20 burns up before hitting the CAT. That, at least is my simple minded understanding of the situations.
The other big voices (the ones who really do know) should chime in here soon.

thanks... that does help explain a little more and seems to be the general thing that i've read hear. i live in jacksonville, fl. we do see hot summers and cooler than normal FL winters. it makes sense that the synthetic would hang around longer and that the thinner oil would burn faster... (which is what the engine does by design from my understanding). this is my 3rd auto and i've never had to replace a cat converter on any of them. i got the most miles out of my honda accord before trading it in... 150K. Are cat converters expensive to replace? i'm considering the 5w30 oil but may just stick with the 5w20 as mazda since i plan to be anal about changing the oil every 3k anyway... what do you guys think. i just want to make sure my baby is around for a long, long time.

When it's really hot, ie 90 plus, don't drive her hard in long stop and go traffic. Of course the AC ain't that strong in stop and go traffic either so you may not want to use her then anyway. On highway trips in the summer drive nice and steady, no high rev passing.

so if i use the mazda required 5w20, keep her nice and steady on hot days and even run the ac more? during the hotter months when im feeling a little frisky, use the thicker oil? also, i picked up a recent copy of MazdaSpeed Magazine and there on page two or three was an rx8 being used to advertise Royal Purple synthetic oil. DO YOU FEEL MY PAIN? what is a responsible owner to do when he wants the best for his baby but then finds that the best may not be the best for her at all. so many race enthusiasts swear by that royal purple synthetic oil.

rx8club.com has TONS of threads on this topic. Some people swear by synthetic, others swear by dino. I just figure I'll go with what mazda recommends.

finally.. someone that realizes they should just use non synthetic. congrats..your car will now last longer than the stubborn people that are like,'but i always use synthetic and it hasnt failed me yet." they will not be hapy when they take thier car to the dealers and the maintenance says they will need a new motor. then thye will think, well cool, it s on the warranty so i jsut got a new motor for free. ERRRRRRRRRRRRRRRRR!!!!!!!!!!!!! WROOOOONG!!!! the second they see there is synthetic oil in that car the warranty is automatically withdrawn from that particular motor and it looks like they jsut paid for the motor themselves. it is simple.............USE NON-SYNTHETIC.

Madzda Extended Warranty

I have an '04 MT with about 35k miles on it. I haven't had any probelms with the car, at least not yet.
Is the extended warranty offered through Mazda something that I should even consider? Or is it really a waste of money?
