I have just over 13000 miles on my GLS and the brakes are squeeling.
Can I possibly need brakes already?!? I'm gonna take it to the dealer
soon, but 13000 miles!! That's a little soon for brakes isn't it?

Depends. I can drive 26 miles to work and if I catch the lights right, I'll
use my brakes three times. When I lived in the city, I'd be on the brakes
every block. These days I get over 50,000 miles, back then I'd be lucky to
get much more than 10,000.

I don't know where you live or how you drive so I'd not attempt to say what
you need. There are other possible reasons for brake squeal too.
 
When do they squeal?

My 06 LX Sonata (~13K miles also) brakes squeal every morning after
rain, or moisture from a hot day and a cool night. It goes away after
I drive a short distance, enough to grind off any rust that may have
generated on the rotors. They have always done this, even the next
day after I drove the car off the lot. My wife's 05 Tucson LX does
not squeal as much, if not at all, in the same scenarios. Hyundai
must have done something differently with the new Sonatas.

I agree with Edwin, depending where you live and how you
drive....endless reasons and answers....

I live in Pennsylvania and of the 13000 miles on the car I would say
10000 are strictly highway miles. I was just wondering if this is a
common sonata problem.

I am in NJ. I have right around 25,000 on my '06 Sonata. My driving on a
regular basis is more city than highway (probably about 60%-40%). At about
24,000 miles I had a noise that sounded like the wear strips on the front
pads. Took them apart to find one caliper bolt needed lube. The pads
actually had about 1/2-life still on them. For me, that is amazing. I
personally never was able to get much more than 20,000 miles out of a set
of front brakes on any car I have owned over the last 25 years (except for
my trusty '88 Chevy P/U).

I know one other person with the same year car and they also have had
excellent pad life thus far.

So I don't think it is a common problem, but I only really have two
personal data points to judge.

My '06 Sonata doesn't, she just clicked 15k miles.

According to my dealer, Hyundai changed the material in the brake pads for
longer life and better wear. We know of course that with this advantage, we
might see a disadvantage (I'm a fan of Murphy).

Most of mine are highway miles as well, but depending on how hard you ride
brakes, you could burn a set up that quick. I replaced the "Lifetime" brakes
on my Nissan Sentra once a year, but that's me....

Could be glazed from repeated high speed stops. Are the rotors black
and shiny?

Could be that the retainers are badly rusted up from salt.

The worst thing in the world for brakes and rotors is repeated
high-speed stops. Some people use the brake pedal to disengage the
cruise control, and that's a bad habit. Whey you're cruising at 75mph
and use the brakes to stop all the way to zero, you're lucky if the
rotors don't get red hot, become glazed, and warp. I'm trying to train
my wife to coast down to 35-40mph before braking, but old habits are
hard to break.

Why don't you walk outside and check them? Your post made me go
outside and check mine, and they have over 1/4" of pad left. I guess
they are less than 1/4 used up. I have 13K on my 06 Sonata too.

Do you think that one second tap will damage the brakes? Really?

Depends on where you drive. In heavy traffic on the interstate, you dare
not coast down to even 60 before you hit the exit ramp and coasting down to
40 may be just plain impossible. I'd certainly now wanto to meet you on the
Garden State Parkway as you are coasting down. Chances are, you'd be rear
ended four times before you got to the exit ramp. Or on Rte 128 outside of
Boston, Or 15 in Las Vegas, or a lot of other roads.

No, nor did I say so.

Your sentiment is mutual. Believe me, I have no desire to drive on the
Garden State Parkway. Believe me, I will never be rear-ended on Route
128 either.

All I'm trying to convey is that braking from 75-0 is an emergency or
panic stop. It will increase the likelihood of warped rotors and
premature pad wear. OF COURSE you have to balance that out with
safety. Even coasting down from 75 to 60 is 10x better than jamming
the brakes on at 75. It's best to coast down if you can. If you can't
without getting rear-ended, well DUH???

Sometimes I wish I had a pad on the driver's seat that duplicated the
brake rotor temperature. A little feedback to the derriere would
educate my women drivers that high speed braking produces extreme
heat.

No, you did not, but please explain why it is such a bad habit? What is
going to happen if we do that? The cruise control switch on my Buick is
broken and I have it jammed on the "on" positionw itha splinter of wood so I
use the brake pedal all the time to knock it off.

Do you have any numbers? Really, not trying to be smart here, but I'd like
to see what the difference is in actual temperature on the rotors for
gradual braking versus harder braking. I cold not even guess at the
temperature. Coasting down makes a lot of sense, but going from 75 to 30 is
not very practical for most of us.

Rotors on cars are made cheaply today and they are more prone to warp beyond
tolerance to turn them down also.

You are so right. And from what I have seen, I can get a set of front pads
AND rotors for under $100 and change them myslef in under an hour. What's
the big deal?

Cobber, I ahve 8000 on my 07 Nf and only 20% worn according to dealer
on Friday and although on country roads thet get used HARD when
dodging wildlife and wandering stock as other posters hint not a
common problem .
But check the nut behind the wheel is some times appropriate but
probably not in your case :)

What you're really saying is that people don't know how to drive.
They do stupid things like accelerate and go full speed toward red
traffic signals and stop signs only to slam on the brakes at the last
second, they ride the brakes and the bumper of the car in front
inching ever closer during stop-and-go traffic, and drive 80 or 90 or
100 in mixed traffic -can't do that for long without having to slow
quickly, etc.

One of the best bits of driving advice I was given was to get the hell
off the gas when the signal ahead was red. Saves gas and you coast
toward it saving the brakes too. OK so you don't arrive as fast AT
the light and you're not doing 70 when you get there, but that's the
point.

On the other hand, if I have to panic stop, I am going to shove the
pedal through the floor. It's much easier to replace some brake parts
early instead of replacing a whole car or fixing a broken driver.

Fwiw back to the OP, my 06 Sonata is about to pass the 1 year and 10K
miles mark. I have also had the squealing brake thing but as the
others have said, it goes away in the first couple stops. It has
stopped bothering me.

Tapping the brake to disengage the cruise is not a bad habit.

Stepping on the brake at 75MPH to stop or turn without first coasting
down to a sensible speed is a bad habit.

But you already know that, so why are you giving me the business?
Do you have any numbers?

Ah... one of those numbers guys, eh? All I can offer you is that it
takes 4x more friction/heat to stop a vehicle from 70 as it does
35mph. That's my point. What's yours?

Guess what? I can't always coast down as slow as I would like. But I
still stand by my statement that rotors become red hot if you brake
from 75mph.

All the more reason to coast down if you can.

Exactly. Cruise control creates some bad habits.

My favorite is a friend that has a big ole Escalade. He cruises at
75-80. Instead of tapping the brake and coasting down, he jams on the
brakes at full speed. I can visualize the Space Shuttle's heat shield
scrubbing off energy and becoming red hot. His brake pads only last
about 20K miles. My hat is off to Cadillac for making great rotors
that stand up to him.

Changing your story? Quoting from your other message:
You made a satement. I just want to know and understand why. You must have
a reason for saying that or you would not have said it. Perhaps you can
teach us something we don't know. If asking why you beiieve in something
you stated is "giving you the business" well, so be it.

See, that was easy. I could not have guessed that and now I learned
something. You made a your point and answered my question. I had no point.
The purpose of t his newsgroup is to discuss, tech, learn. Thank you for
contributing. FWIW, numbers can be applied to most anything mechanicla nd
helps us to udnerstand what is going on. I'm a cruios kind of gy though,
and I'd like to know just how hot rotors can get.

I don't believe that one quick stop from 75 MPH will make the rotors red
hot on any vehicle with reasonably well designed brakes.
