High pitched squeal when braking-2009 Jetta S by dvsgelatin
May 19, 2009 (7:53 am)
Reply
I have a 2009 Jetta S Auto w/about 600 miles on it and my brakes are already letting out a loud squealing sound about 25% of the time that I brake to a full stop.
 
According to the dealership, "the brakes on a vw are vented rotors, no squeak or rust prevention can be used on them or it wont vent the heat of the brakes properly. The noise you hear is surface rust being removed from the rotor."
 
Does this sound like a legit explanation?

I posted some comments earlier ( post #121) concerning Jetta rear brakes. We own a 2007 Jetta base model and I have experienced slightly higher than normal rear brake pad wear also. I do all of our Jetta's maintenance and discovered the rear parking brake cables were adjusted too tightly (out of factory specified limits). Each rear caliper has a separate cable used to apply brake force to its respective side with a primary tension adjuster (for both cables) in the center console. The left rear brake pads were wearing faster than the right rear and a quick check in the Bentley factory manual confirmed what I suspected, misadjustment from the manufacturer. The cable adjustment for most cars is easy to access...but not with the Jetta. The rear half of the center console in the cabin must be taken apart to get to the primary adjuster.....this is not a 10 minute process. After the primary adjustment is accomplished, each caliper is then adjusted. Long story I know however, this may be a reason for higher than normal rear brake pad wear. Have your dealer check this. The inspection is easy and done at each rear caliper. If your car is out of warranty and adjustment is required at the console, this will take approximately one hour to accomplish. The actual adjustment is easy...but having to open the console is a pain.

You cannot apply any compound (oil, etc) to brake rotors. Squeeling disk brakes are a sure sign of brake pad glazing. Glazing is caused by heat and the normal fix is pad and or rotor replacement. The rotors themselves are cast iron and will rust immediately when the car isn't driven. This is normal and you may hear the pads scrubbing the rust away for the first one or two brake applications but squeeling is not normal. Is the squeeling noise from the front...rear...or all four brakes?

Jetta rear brake pad wear - my two cents worth... by oilburner613

I checked this forum because my wife's 2003 Jetta wagon started emanating uggly noises from the rear recently, which I found rather odd, based on my nearly 40yrs of driving (rear brakes wearing out before fronts, that is). Having spent the past 30 mins reading the various complaints/rants, however, I guess I should consider myself incredibly fortunate, as this 5-speed car has over 151,000 less-than-gentle miles on the original brake pads. Granted well over half are highway miles, but my wife doesn't baby the brakes and we always use the parking brake. I know this doesn't make the people who are having problems feel any better, but I felt it was important to share our positive experience. Mark, in NC

The rear brake rotors are solid, not vented so that is a line of BS in itself. Their statement about "squeak or rust prevention" and it's relation to venting is just plain bizarre. Anti squeal compound goes on the pads not the rotors and any rust that forms on the friction surface of the rotor would be scubbed away in the first few minutes of driving/braking. Assuming that you haven't parked the car in a pond for 6 months.
 
You have to remember though, the service rep. is more likely to have a degree in finance than an ASE certification.

Rear pad premature wear - 08 Jetta Se 18K miles by paintchip
Jun 11, 2009 (10:01 am)

My rear pads were completely gone at 18K miles (fronts still have at least 85%). There was no warning or anything, just started grinding when I hit the brakes.
 
I was lucky enough that it happened near enough to my house to limp it home. Since it was a Saturday and I had a busy schedule for Monday (and didn't feel up to fighting with the stealership either) I went ahead and bought the pads and rented a caliper tool at AutoZone. The pad swap went smooth and I thought everthing was good until my front brakes started dragging and overheating on Monday.
 
I've done plenty of pad swaps on cars and this one has me dumfounded. I've been told that it could be anything from a bad or misadjusted brake booster to sticking front calipers. The oddest was a theory that the pads I bought were too thick and that VW has about 10 different variations of pad thickness and have to be ordered using the vin#. If that's true...what a scam!
 
I'm not even going to try the dealership or VW USA at this point so I'll check the front calipers this weekend test the booster. Not sure how to test the pad thickness theory if it comes to that.
 
I'll post the resolution if I find it.

I am 45,000 miles into my 08 and about to replace the pads for the 2nd time. Hopefully not rotors as well. After complaining to the dealership the first time that brakes wearing at 15,000 wasn't normal, I went to someone else to install the brakes. It is most definitely something wrong with the rear brake system. I was told that it happened because I used the parking\emergency brake when I at an incline occassionally. I haven't used it since and my brakes are still having issues.

2007 Jetta--love the car as I am short and I finally found one I can see out of, easy to get my toddler in and out of the car seat, a good car for me. How suprised I was when my back left brake begin a crazy Chewbacca noise and was told it was the brake! 35, 503 miles on it, have only had it for 7 months, the dealership has already pissed me off for some other issues, and now they tell me it will be $360 dollars--also they did not have the parts in stock! At the dealership! The only reason I went in was because with the noise and lower mileage I didn't want to screw up using my warranty...live and learn I guess, but I will file a complaint with the organizations you all have mentioned.

Rear brake wear on '06 Jetta by jettadrvr
Jun 23, 2009 (7:56 pm)

My VW Jetta has about 53,000 miles on it and I just found out today the rear brake pads are nearly worn through. I started getting some vibration through the brake pedal about a month ago, so I called the dealer and was told that the FRONT brakes have a wear indicator/warning light, but the rear brakes don't, and that I probably have a warped rotor. The mechanic (at a local VW repair shop) who looked at the brakes today was surprised to find out there aren't wear indicators on the rear brakes. He said the front brakes are good for quite a while longer.
Seems VW is thinking the front pads should wear out first, otherwise, why put the wear indicators in front only??
 
I live in an area with lots of steep hills and hairpin turns, so pretty much have to ride the brakes to maintain the posted speed limit and avoid going off the road. I was wondering if that had something to do with it, but based on the other posts, it is a design flaw with the braking system. drdata, did you get a response from VW Corp?
 
fyi, the dealer quoted me $450 for new rear brakes and rotors (sight unseen) but the local VW repair shop is only charging $325.
