Brakes That Wake The Dead

[BacktoHyundaibychoice]

Here's the story, point by point, followed by my dealer's response:

1. Took delivery of my 4.6 w/Tech on a Wed. afternoon. All was well, and quiet, until Saturday morning when:

2. Backed out of the garage, and when I applied the brakes going down the driveway, there was a LOUD squeal/grinding. When I put it in Drive and applied the brakes there was silence.

3. I drove about 1 mile, parked for about 2 minutes while getting my coffee, put it in R and the was NO noise from the brakes.

4. Same thing happened on Sunday and Monday mornings, and after the car sat at the train station all day. Only in R, never in D, after sitting for an extended period (10-12 hours?). And did I mention this is a LOUD squeal/grind?

5. Made an appointment for the brakes to be examined on Saturday. This is what the tech said:

"Checked brakes front and rear, all checks OK. At this time, some noise is normal when braking in reverse due to glazing on rotors".

Normal? I think if this howling was normal I'd have read about it here, right? All I know is that my neighbors liked the car when I brought it home. But I know they can't appreciate the 5:30 wake-up call I'm providing.

Thoughts? Suggestions? Anyone else?

I completely understand. My GEN does it as well, not half as loud as you say yours is.

Practically every car I have owned will do this in the bitter humid cold. ESPECIALLY after a good rain and the rotors have time to rust...or, GLAZE.

This is no issue to me nor my neighbors so I wont complain.

Loved the title of the thread.

I had a Honda Prelude that did something similar (years ago) and I let my brother the mechanic look at the car because the grinding sounded like I had no brake pads left and it was metal on metal. It was not as loud as yours seems to be

He told me something along the lines of what PING GOLF said...that it would happen in cold weather, after the car had been stationary for awhile and in damp weather. He told me it would just be the first time I hit the brakes...hence backing out the drive first thing in the morning.

I have the same problem when reversing the first time after the car had a chance to rest. This actually started after I took a 250 mile trip in poring rain. There was no noise before the trip.

I'm having the same problem with my V8, reverse only. I'm sure going to my dealer would be a waste of time.

It also happens when the car is washed, but that is from brake dust accumulating on the face of the rotors, which looks like rust

Its common for the rotors to develope a surface rust very quickly in humid or wet environments. It usually comes off the first or second time you hit the brakes. For my car that sites outside I back in the drive way so when I pull out I don't have to hit the brakes until I am down the road. Since I'm in a very humid area the Genesis stays in the garage with a dehumidifier so no brake sounds when I back out. Last week I washed the Genesis and went in to eat lunch. When I came out the rotors had already started to get a rusty haze.

I to have a terrible squeal with the brakes on my 4.6 Genesis. I agree with other members when they say they have had other cars do this as well and so have I.

I will say however that my Genesis puts out by far the loudest squeal I have ever heard!

Maybe since I don't even have 600 miles on the car and have had it since a few days before Thanksgiving may help explain it.

My wife and I just use our Genesis on weekends mainly. I get the squeal backing out of the garage and for awhile moving forward.

This morning even after driving the car to church, when we got out of church and started moving forward I had the squeal again at the first stop sign.

I must say however the conditions here in Iowa are absolutely terrible! We had blizzard conditions today with a high of -2F degrees below zero with a wind chill of -20F to -40F below zero with alot of blowing snow in the air!

This kind of weather may certainly be playing a big part in the squeal of the brand new brakes that may not even be seated properly yet.

I will say that with 40+ mph winds the car is remarkably quite with almost no wind noise what so ever.

The heater was quick to warm and the heated seats very quick to warm. We were very comfortable inside with the temp set at 76F. My son was also nice and warm in the rear seat. He commented on how much he loved the heat coming out of the rear vents.

Despite the extreamly cold temps and high winds I still managed 22.3 mpg including a brief engine warm up when I first fired up the 4.6 V-8.

I could only drive about 45 mph however due to snow packed and icy road conditions. The Dunlap tires actually did way better than what I expected based on what others have said. I think at least half of all winter driving effectiveness is just plain common sense moves by the driver. So far I am satisfied with the driving behavior of the Genesis on slick roads.

I'll get another chance again already tonight to test it out on the way to a birthday party. At least I should be warm as the temp is forecast to get down to -18 degrees below zero staright temp. not counting the windchill.

I just hope my brakes finally quite making that terrible squeal. Afterall my cheap little 06 Hyundai Elantra doesn't do it. Oh well.........

like i've said to many car owners, "the brakes makes noise because of water accumulation on the rotors and pads. But after the first or 2nd braking application the intense heat of friction cleans the surfaces off and the water evaporates, the sound is no more!"

I had a customer that told me, "Oh but my shiny new Honda doesn't do that, (this was back when I was working at Toyota by the way." And lo and behold on the test drive there were no sounds from the brakes... IMO people are just too paranoid and not realizing what hours of metal and water can do...

I have three other cars but none of them make any squealing noise when backing up the first time each day. I am sure it has something to do with the brake design, and materials for the rotor and brake pads.

Same thing on mine -only once so far. It is a very load noise, unlike other cars where I've heard it in the past. Not sure I'd call it a design flaw - maybe a quirky annoyance.

 

[Sonata2009]

In defense of philmcneal, I have a 2002 Caravan, and if it's been wet, and sits for a day or two, it gets very rusty rotors. Not so much a squeal, but you certainly can hear the brakes for the first few stops.

I used to live in Houston, and the dampness and heat only made it worse. No harm done, just some noise until they clean themselves off.

 

[philmcneal]

yea like i tell my customers, if you been driving for 15 mins and you still hear brake noise then yeah we'll have to check it out. But after the car is warmed up and the car's brakes make no more noise then, oh boy... the infamous NO FAULT FOUND will be written on the work order

although honestly a squeal usually indicates more than just rusty rotors, you would hear a "KURRR" when there is rust, but a squeal indicates more than just rust, sometimes glaze or a warped rotor could happen.

edit: this topic bugs me, because its always a mystery with brakes. Is your drive way down hill, does the same thing happen while in N? Try this experiment before you back out of your driveway next time, like pumping the brakes before putting it into gear. See if lubing the caliper slides can do anything about it, and do you think the noise is in the front or in the rear?

I wonder if one were to dissemble the front pads and lubricating everything again including machining the front rotor would make the noise go away? Or is it truly a design flaw.

 

[Bear]

I have a question. Are all of us having the brake problem V8 owners? It looks that way.

 

[Sonata2009]

Despite the Caravan comments above, I've got a Gen V8 with nary a sound out of the brakes in 4000 miles.

 

[JOwest]

Mine is a V8 and only make squealing noise when backing up the first time each day. Absolutely no noise when the car was moving forward.

Found the cure, or workaround if you prefer:

Before engaging R, I apply the parking brake but only 2 "clicks". When I use the brakes I get sweet silence! As with most bright ideas, I discovered this one by accident: had forgotten the PB was engaged at the train station all day and backed out quietly. In D I noticed the red dash light and said oops! Then I realized 1 plus 1 equals 2...

Anyway, I assume the PB is either scraping the rust off or muffling the howl. Don't care, my neighbors get to sleep in.

 

[Eliott]

No noises here.

hmmmmmmm there is a tsb about brakes squealing early in the morning, however, the fix is only avaiable for the v6 option. Although you pumping the brakes before reversing indicates that you probably lubed up the caliper pins before having them being operated for the first time when its dry.

The tsb i'm talking about only replaces the metal clips that the brake pads sit on, but in your case I would suspect the caliper pins, YMMV.

To my understanding you can't scape the rust off the pads and rotors unless you start moving. but in your case you pumped the brakes before moving and the noise was gone, therefore my money is on the caliper pins!

edit: scratch that i didn't realize that "backtohyundaibychoice" he used the parking brake before engaging into reverse gear, so there goes my bet.

I have the 4.6 and the brakes were fine until about 400 miles... Now they wake the dead! But like most people say here, it only does it for the first couple of brakes, then it stops... The only other vehicle that has ever done this has been a VW Jetta... Brought it in, they replaced the brakes, the squealing stopped... I'll be bringing it in along with a few other issues... My passenger front door seal light doesn't work either.
