#288 of 311 Back brakes again, again, again................
Sep 30, 2011 (1:36 pm)
I'm an owner of a 2007 sonata and from day one my back brakes have been a big dissapointment. When I first heard the high pitched noise at 15,000 miles to took my car into the dealiership they said that nothing was wrong and it was in my head. I let them know what I thought. I don't know how many times I have change my back brakes but I still have not change the front ones yet. I still have 30% let on the front ones. If you own a sonata BEAWARE I just change my back brakes two weeks ago and yesterday a grind could be heard from them again I inspected them only to found my driver side inside pad was completely worn off. And the outside pad was dust which happens at very high temps. Look at my brakes my drum must of keep on pushing and worn out the brake pads. I'm shock to see how many others have had the same issues only for the dearliership's to say not our fault.
Here is the easy solution I'm buying another car and you can bet it will not be a Hyundai
#289 of 311 Bad Brake
Oct 05, 2011 (12:33 pm)
My mother's 2009 Sonata needs rear pads at 25,000. The dealership gave me the same mumbo-jumbo about rust, etc. and tried to tell me that mileage was the norm for rear brakes. You have to be a real theif to be a service writer. They quoted me $290 for the rear pad job and said it wouldn't need any rotor grinding as i had caught it in time. I was getting the same grinding sound with turning the wheel to the left as I drove and also at start up I would get the same. I took it to my regular mechanic and they quoted me $220. My Mom is pretty conservative and bought the Sonata because of the warranty. She thought she could keep this car longer with the long warranty. She now wants to dump this car as soon as possible after reading the previous posts.

Wow. If you can do your own brakes, the rear pads are a cinch to change, and they're cheap. The job only takes me an hour and $50, and that's probably rounding up. And 25k miles sounds right, I think. FYI, I get a grinding-while-turning noise in my 07 Sonata every once in a while. This is from the pads getting hung up in the slides. If the dealer "fixes" it, they just take everything apart and clean it all really well, so I now do this myself. Easily the hardest part of a brake job on my Sonata is removal of the front rotors, which I still have not attempted (there's a bolt is a real tight spot).

I had an 08 Accord and got rid of it because it ate back brakes for breakfast. I don't know if you all will buy this story but it made the most sense to me. Ever since cars have had electronic stability control people have complained about back brakes wearing very fast. Well someone on the Honda forum suspected the electronics were pulsing his back brakes every time he went around a corner. Makes sense to me but who knows. Honda blamed bad parts Hyundai blames bad parts maybe its really the dreaded electronic glitch. Just a thought and I am sure the experts will chime in.

Not an expert on the matter but it is my opinion that older cars (pre 2000 anyway) had rear brakes that never wore out because they mostly went along for the ride and contributed very little to actual stopping whereas the fronts did most of the work. Now there is a brake proportioning system in play that distributes braking force more evenly between front and rear therefore it stands to reason that if the rear brakes are now being actually asked to help stop the car they WILL wear out at roughly the same rate as the fronts. Additionally, the change in pad materials that is now mandated because asbestos has been removed (a good thing) has affected brake pad/shoe life. I have a friend who owns and operates a small garage and he has seen brake pad life both before and after the change in materials. He swears brakes do not last as long as before and has to field complaints such as these from his customers. These observations are from regular customers whose cars he serviced before and after the removal of asbestos. So, all these small but important changes have, in my opinion, caused rear brakes to wear quicker now.

Not sure when you think the change-over in materials happened but I suspect it's been quite some time ago. With that in mind I have a 2002 Mazda Protege with 103,000 miles and about 50% of the original brake pads left (4-wheel disk) in both the front and rear as of about six months ago. This is per a shop inspection. I live in missouri and we get plenty of road salt. So I would beg to differ with people stating that 25,000 is normal. I have had the same type of car from Mazda for the last 20 years and the brakes are always long lived. For what it is worth I think there must definately be an engineering problem with the car. This whole web sight has made me rethink what kind of car i will get next at the end of this year. Should have been a slam dunk with a sanata but not anymore. I don't feel like dealing with some moron who says this is all normal. Been there done that.
#294 of 311 Noisy Clattering Front Brakes
Oct 17, 2011 (3:17 am)
I have an '07 GLS with almost 58K miles. At 49.5K miles I had the front brakes replaced by my Hyundai dealer so they also resurfaced the rotors, serviced the calipers and slides. Since that time when I'm braking or turning at a slow speed I hear a clanking or clattering sound from the front brakes, similar to the sound a CV joint makes when it's in need of replacement. It has no adverse impact on the car's ability to stop. I've had it in to the dealer, they've heard it but can't identify what is causing it. They've also taken the brakes apart and said everything seems to be OK, just keep listening to see if it goes away. It hasn't. Taking the car in next week for inspection and mentioned to my service writer trhat it's still there when I made the appointment - said they'll look at at. Anyone have any idea what it might be?

Yes, it has been some time since the US government banned asbestos from all commercial use and yes, I still maintain that the alternative materials might not last as long but in the end the length of time anything lasts depends on the consumer and their driving habits, good or bad. I just spoke with my sister who lives on the west coast in Portland and inevitably I asked her about her car...long story short, she mentioned she just had to replace the brakes on her 2003 Elantra (a Hyundai product you will notice) at 167,000 miles. When I expressed amazement she said she always downshifts to slow the car (manual transmission). For the record I NEVER got anything remotely near this type of mileage but I have an automatic and routinely drive in the mountains, so is my car defective...I don't think so. So is 25K normal for some? probably.

I am an owner of 2010 Sonata, which ran for just 30,000 miles. Recently, I noticed that during braking (from any speed above 20 mph), there is a sligtly shock or chattering (from breaking system) when the speed reduces to about 20 mph (especially when is car is cold). When the car is warm up or run for a while, this shocking or chattering becomes smaller. When this spedd is below 20 mph, the braking is smooth. I brought this car to the dealer, and they did not find any mechanic issues with the brake pads or rotors. Does anyone have similar experience? How to fit it?

I agree with you on the proportioning system as part of the reason for increased rear pad wear. I also think that electronic stability control plays its part, however the design engineers are at fault as well. By not increasing the size of the friction surface for the rear pads to equal the front, it stands to reason that smaller pads, asked to do the same work as the larger fronts, would wear faster. In this case "SIZE DOES MATTER".
