Hi, guys!

I have some confusion on front brake pads for 2006+ 3.3L model.

After some online research, there are two different types for 2006+ 3.3L model: part number with 924 and 1125. I picked 924 and installed on my 2006 Sonata; however, its width is about 1/8" shorter than OEM so it does NOT completely cover the swept area of rotor. I suspect that 924 perfectly fits to 2.4L model which has smaller rotor diameter than 3.3L model, but not to 3.3L model.

The description on Kragen or Autozone confuses me more since they list the 924 can fit to 2.4L and 3.3L for 2006, only fit to 2.4L for 2007~2008, 1125 only fit to 3.3L for 2006, so on...

Has anyone tried 1125 like Bendix D1125 or D1125CT? I need to find perfect fit for 2006 3.3L model (Production data: 10/31/2005).

....Why start yet a NEW thread, if you had one just yesterday, and got some helpful responses, kali76?

Well from what I my Sonata Service Manual the 1125's are for sonatas made from 4/1/05 to 10/10/05, then the 924's are for 10/11/05(they changed the rotor) on. You say your p-date is 10/31 so you should have the right pad. Unless somehow you got yours w/ the wrong rotors on.(was 10/31/05 a friday or monday)HaHA.

Oh snap, 10/31 was a monday.

Putting wrong rotor from factory? Come on, give me a break.
I am just curious is there anyone who used 924 with perfect fit?
So far, I heard none.

I was intended to delete yesterday's one. Just realized that it seems not allowing to delete it.

I don't get much helpful reponses. I wonder people are not interested in brake pad compatiblity or I am just asking a question everyone knows?

I have another question on brakes. Are the OE brakes ceramic or metalic and is there any way to tell. I dont know if my rotors will handle ceramics. 06 GLS prod date 8/9/2005.

I ordered the AKEBONO Part # ACT924 {ProACT Ultra Premium Ceramic Pad}
Ceramic; Original Equipment Ceramic; Front

Fit perfectly for me. The description also states ceramic is the original equipment.

Ceramic is not OEM.. they come with semi-metallics... i know what you are reading and it makes it sound that way, but i know the OEMN pads that come with the Sonata's are not ceramics...

however, as Ruthless said, the 924's are what just about every place i have seen says is the correct fit, and that's what i bought to replace mine in the next couple weeks (Raybestos ATD924C Advanced Technology Ceramics)

I am confused. Acording to the manual above I should get 1125's. Is everybody using 924's regardless of build date, and is everybody using ceramics regardless of what came as oe? Will 924's harm the rotors if they are the larger rotors, and will ceramics harm oe rotors?

1125 is the model number some brake manufacturers use. (Bendix, Centric, Monroe)...

924 is the model number other brake manufacturers use (Raybestos, Akebono, AC Delco, etc)..

they are the same size... the manual says 1125 because it is Centric brakes that come OEM on the cars (i think)... using 924's is perfectly acceptable as I believe they are the same size (again, not positive of that), but more places I have seen lists 924's as the correct size for the V6...

I am not sure if ceramic pads will harm the OEM rotors. I am inclined to say no they dont harm the OEM rotors, but I cannot be sure of that. I bought after-market rotors since the OEM's are grooved on my car, so they need to be replaced anyway...

bendix ceramic pad part for the fronts is D1125CT
bendix ceramic pad for the rears is D813CT

using a cermic pad will shorten the life of a oem rotor

Do the oem pads have wear sensors?

only the squeaking noise..

The short answer is go with the D1125 for the V6 if you can find them because if you are like me, you want parts to match what is being replaced. However, using the D924 pads will be fine.


For those who want the long answer, a little information on brake pads....

The numbers that you see on the boxes (i.e. D924, D1125 etc) are created by the Friction Materials Standards Institute (FMSI). FMSI will announce a new number to Friction Material manufacturers. The manufacturers will then purchase an OE sample from the dealer to review/reverse engineer and determine if they will add the number to their product line. Sometimes, companies will determine that the number released by FMSI is similar to another number they already have available so they will consolidate numbers. This is the case with D924 and D1125. They are very similar but not identical but some companies chose to consolidate the D1125 and D924. FMSI catalogs the D924 as fitting 2004-2009 2.4L Sonatas(and others) while D1125 is listed for 2006-2009 3.3L Sonatas (and others). See attached FMSI drawings of D924 and D1125. You will see that there is a difference in the friction profile as well as the backing plate design.




Companies like Bendix and Monroe have both the D924 and the D1125 following what FMSI catalogs.

Some other facts:
1) The OE manufacture of the brake pads for the Sonata will either be Korea Beral or Saeron Automotive. Neither of which market their pads in the aftermarket.

2)Ceramics were developed to reduce dust and noise. As with anything else, there are some good ones out there and some bad ones. A good Ceramic pad will have great pad and rotor wear capabilities as well as be low dusting and low noise. A ceramic will not give you the stopping power that a semi-met will.

3)The OE pads for the Sonata are "Ceramic"

Just the info I have been looking for, for quite a while. Thanks, now I can replace my pads with confidence.

Purchased OE pads at Kelly Hyundai in Butler PA and they are Metalic made by Korea Bearl. The dealer said they did not use ceramic as OE.

I have a new problem. The 2 Phillips screws that hold rotor to hub are frozen and can not be cacked out. Anybody else have this problem?

I would just leave the rotors alone and put up with the vivration but I noticed the inside pads are worn on an angle on the side closest to the axle. I also noticed the rotor has an elevated surface on the inside closest to the rotational center, Is this normal?
