Hi I have a 2006 Sonata GLS and have noticed what seems to be rust on
the rear wheel drum where it joins the brake disk. I was wondering is
this normal or should I raise it on my next service visit to the
dealer. I can't notice any on the front wheels though which is what has
me stumped. Any thoughts and solutions welcome....

Normal. It is cast iron and will rust. Due to the heat it gets, there is
no way to paint it. It may however, after about 100 years rust through.

Are you talking rotors or drums? I thought all Sonata GLS where 4 wheel disk
brakes
If rotors, yes if you are in a humid climate, and you don't drive it for a
day. On the other hand if drums, my other two vehicles that have drum brakes
in the rear, obviously, have never, ever had a lick of rust in the 13 and 9
years we've owned them. They are made of a good grade of steel, and a good
paint job, and like I said have never ever rusted.

Happens to lots of cars including the quality Japanese ones like Lexus,
Toyota, etc.

Brake rotors won't be made out of the purest alloys (got to keep costs
down) so some rust will occur.

I would not worry about it but if it really bothers you paint it with some
silver rust paint.

I have a DIY project on Garage Page 1 on the Drivers & Believers website at

I beg to differ big time. Not only can they be painted but the painted
rotors on my late Elantra GT were 4 years / 40k+ miles old and still hiding
all evidence of rust.

Good prep and good paint and the problem is cured.

Sonata's are 4 wheel disc but have a drum for the parking brakes. In my 45
years of owning cars, I've never seen a brake drum that wasn't rusted. Yes,
you could paint them with High Temp Paint after some good prep work but
why?? I am truly amazed that razz has been lucky enough to have two older
cars with no rust on the drums. Did you paint them, 'razz'???

Sonata Gl's have disc on the front and drums on the back, at least the early
2000s, GLS are all disks. In all the years I've serviced disc brakes
vehicles, I've never seen a drum for parking brakes, not even on my 2001
sonata GLS, which are all disc brakes. There is a parking brake cable (hand
brake cable ) that goes to the caliper. As for rust on the drums it is
common but most of the vehicles I purchased had high grade steel with a good
factory high heat paint on them.

My 2006 Sonata has discs in the back but there's what looks like a drum back
there a little larger in diameter than the bolt circle. I assumed it had a
shoe in there but I haven't crawled under to look. But I will just out of
curiosity. )

What kind of cars do you buy, razz, with painted brake drums? Very
interesting.

Tom,

Brake rotors are like hats where the rim of the hat is the shiny part that
the calipers rub against and the crown of the hat is the part the studs
pass through.

No drum or drum brake shoes on your Sonata.

Yes, Wayne, I know what discs are, but have you looked at the rear wheels of
a 2006-7 Sonata? Not what you are used to seeing on a disc equipped car.
The 'Crown' is probably 3-4" offset from the disc. Maybe it's to give more
room for the caliper but you never see this on the fronts.

Well, I hate to break it to you, Wayne, but the Sonata DOES have rear brake
shoes in a drum for the parking brake system. I just logged into the
Hyundai Tech site and looked at the system. That's what's inside the
'Crown' that you mentioned. I have to be right once in a while.. ) I
just waited until November to be right this year. Just ask my wife. She'll
tell you.

Hmmmmmm... the use of a drum for the parking brake is a very common design.
I'm surprised you've never encountered it. What sort of vehicles do you
have experience with? As for rust on the drums, I've never seen a drum come
from the factory with any kind of paint on them, let alone a good high heat
paint. What is a "high grade of steel"? A quick look at a drum will reveal
that it is cast. No such thing as a "high grade of steel" here. Methinks
you're woofing a bit here razz.

I second the motion, Mike. I don't think any car company would incur the
cost of stainless or monel for brake drums. )

Hmm .. learn something new every day I guess - I stand corrected.

I wonder if my Tiburon and the Elantra GTs have this same hybrid brake
system at the rear.....?

Must check Webtech when I am next on my laptop.

Follow up ... I was under the Tib today and the parking brake cable runs
straight to the calipers. This was confirmed by Webtech, i.e. while the Sonata
has drum shoes insides the crown of the rear rotors, the Tib has no such
configuration. Neither did the 2002 Elantra GT I had.

So, there are both types.
