Passat (B6) :: 2008 - Grinding Sound When Brakes Applied
Jan 18, 2011
2008 Passat Komfort Wagon with 34,500 miles. Started to get grinding sound when I applied brakes, which diminishes as I drive. Thought it was rust, but sound is very loud and sounds just like pads are gone and digging into rotors. The brake warning light is not on.
Dealer told me rear caliper was closing unevenly and recommended service---not covered by warranty of course. When I picked-up car same noise as before. The service manager told be that the car was just washed and the rust built up in the last hour---I could believe some built-up, but the sounds made my teeth ache. When we went for a test drive the noise got quiter, but was still apparent. The SM told me this is a "normal" noise. I have had many cars with disc brakes, dating back to a 1960 Jaguar; none have made this "normal" sound.

I noticed yesterday a sound, like a grinding sound, *sometimes* as I apply the brakes to stop. I'm at 68k. The noise only happens when the brakes are applied so I suspect there is an issue with my brakes again.
Some BACKGROUND info: At around 60k (or 8 months ago roughly), the front pads were replaced after the brakes were squealing and a pulsating brake pedal when stopping. The pads were replaced by a dealer. In addition, both front/rear rotors were turned at the same time. Rear pads had 40% at the time and were not replaced.
Some weeks later the pulsation came back and I went back again and they machined them again. For this current issue I was thinking about taking the car to someplace local (not a dealer) and getting a free brake evaluation of what is going on.
I'm also concerned that all this machining the dealer did to eliminate the pulsation may have decreased the life of the rotors and perhaps they need replacement now.

Back in April when I was getting my car inspected the mechanic told me I needed new rear brake pads. I knew I did so I let him change them.
Now I get noisy brake pads this moaning sound out of them when I apply the brakes while I'm backing out of a parking spot or my driveway. I've only driven about 5 or 6 hundred miles since then.

Over the last 2 wks or so I have been hearing grinding noises out of the right rear brake. 1 day it sounds like it was metal on metal. Think is just all the road salt catching between the brake pads?

Is it just me or is this an ABS thing? during a snow storm i was going about 25mph and had applied the breaks and started making a grinding noise... if it is the abs how are you suppose to work with the response time for a quicker stop.

Here's my issue, after a full break job my right front brake began to grind. Curiously it wouldn't grind initially after breaking soon after start up. I could go on and slow break for quite a distance, but soon after a hard brake or just slow breaking long enough the grinding begins. I've taken the car back to Firestone three times and even after a few adjustments or cleaning the problem persist... I've starting to feel bad for Firestone and embarrassed to be holding on to this 99 Chevy. I can't continue to drive this small car that sounds like a MTA bus while braking.
But I digress... I did notice, purely by accident (or it may be a mere coincidence), a few times the ABS light came on and during those periods the grinding was less abrasive. This leads me closer to believing the issue is with the caliper.

Coming to a left turn signal I was anticipating it turning red on me, and I drove into the turn lane briskly 30mph and then applied brakes as I made a u-turn. It sounded like a cross between dragging the front air dam and metal on metal brake grinding as I made the turn. Stopped immediately and did not scrap the air dam and all front end components checked out, okay. Car is driving just fine now, has only done this once.

1950 cadillac - standard drums on all 4 corners.
I put new wheel cylinders on each drum, and replaced the drivers front hose, as it was clogged. The passenger side I left because it works and doesnt leak. I've cleaned all the brake surfaces, shoes and drums, and bled everything.
When I brake, and only when I brake, the front right makes a grinding noise and the car pulls to the right.
I tried tightening the star wheel today to bring the shoes inward in hopes that would equalize brake pressure up front, but when trying again today, I got that grinding sound still.
There is no scoring or gouges on the shoes, drum, and the inner and outer ball bearings seem fine - round chrome balls with no discoloration, no gouges on the spindles. Granted I don't drive this far at all, especially now that I have this grinding.
How can I really tell if its the ball bearings? It only makes the grind when I am on the brakes.

I have a 2007 Toyota Camry 4 cylinder and the ABS light comes on intermittently. Not only does the light come on, but sometimes when I apply the brakes, the brake pedal makes a grinding, vibrating sound that I can hear and feel under my foot, and feels as if the brake pedal is going to go all the way to the floorboard. If I quickly pump the brake, it stops that sound and the brake works fine.
I have taken the car to O'Rileys and Firestone and they put it on the analyzer. Two codes come up which indicate that the right front ABS was bad and/or an open circuit. I replaced the ABS sensor, but the problem described above persists. I took it back to Firestone and the same codes displayed. Firestone said it was an open circuit and that I should take it to the Toyota Dealer. I called the Dealer and they want $135 to analyze the car. They won't tell me what they will do in the analysis. I also took it to Just Brakes and they kept it for 3 days and could not or did not do much other than suggest I take it to the Dealership. I have read that the Dealership will probably say the ABS computer needs to be replaced ($1,000). I have also read that the 2007 Camry Hybrid ABS brake system has been recalled, although my Camry is NOT the hybrid.
There has had two fender benders on the left front side and the right front passenger tire hit a curb which bent the tire, but the tire has been balanced (not sure if the wheels were damaged in these minor accidents or if the wheels could be causing this?) Other thing that occurred right before the ABS light started coming on, and the brake issue, is that the air conditioner went toes up, and there were small metal fragments within the air condition housing unit. I replaced the whole A/C unit. I haven't been able to assess if one would have anything to do with the other, but it is interesting that the ABS and brake issue all started within a few days of the A/C unit being replaced.

I have recently had the rear brakes on 2001 Aurora replaced. When car is driven about 20 minutes, there is a rubbing sound from the rear when the brakes are applied. I have taken the car back to the shop and they said for some reason the new pads were worn and put new pads on thinking it was bad pads. The noise continues. Is there anything special that must be done on this car when the rear brakes are serviced? Are there special type of brake pads that must be used for rear disc brakes? I am just going to sell the car if I can't figure out how to fix this problem soon.

I bought my 06 Corolla LE last week and just started hearing a nasty squeaking sound whenever I applied the brakes. I took it to the dealer today and 4 hours later he calls me and tells me that he had to readjust my back brakes and lube them up and it should be fine..About a half hour into driving the car around town I start hearing this noise again. Now he's telling me to bring back in the morning to see what the issue is.
My question is besides the brake pads and rotors which were checked by another mechanic that said they were good what the hell could be the issue?

my 99 s/w 2 started making a squeaking sound coming from the front right wheel area it goes away when I apply the brakes? is that one of those built in warning features to let you know the brake pads are getting low? the brakes have 86,000 miles on them.

I have a question: when physical brakes applied (at the end of the slight braking, or when speed is small, or when gasoline engine starts on parking car, or when i apply brakes on parking) i hear light "pssst" sound. It is like sound from back door stay assembly, when i open back door, or like suspension shock adsorber works. My local service bleed the brake fluid, but it doesn't work. When we bleeding rear brakes (left and right) and opens bleeding plug, that noise sounds continuously until we close bleeding plug. And there is no air in old brake fluid... Technician says, that sound is normal, but i also have Toyoyta Prius 20 and there is no noise while pressing brake pedal... I just want to ask: is that sound normal for Prius 30 or not?

My wife told me she was hearing a squeaking sound coming from the front end of our 2006 Prius (90,000 miles) along with a noise when she applied the brakes.

My car sounds like it's dragging something but when I look under it there's nothing there. The sound it makes is comparable to the sound a snow plow makes as its plowing the road. The sound is constant but gets worse when I brake. What could be the cause?

Yesterday I had my snow tires installed at Costco. Immediately afterward I noticed that the rear brakes squeak when I apply the brakes. I took the car back to Costco and asked them if they applied the proper torque or if anything unusual appeared during the change-over. They said no.... I loosened and retorqued the wheels and no change......they still squeak when I apply the brakes.
Questions: I assume there are wear indicators on the rear pads, could this be causing the squeeling? If so, aren't they supposed to squeel all the time when they reach their limit? I haven't inspected the wear yet...... What the tolerance is for the amount of lining on the pad. Could this be a rotor problem? I"m not feeling any pedal vibration.

I have a 2001 f150 4x4 5.4 Liter 72000 miles. There is a rubbing sound that is only audible when the brakes are applied. And only when applied with light pressure. The noise will continue intermittently until you come to a complete stop. If the brake is applied aggressively there is no sound at all. I am not sure if it is a brake issue or some thing in the front end that is flexing when slowing down.

I have been doing my own brakes for years. I have had some that were not easy to keep from squealing but this one has me wanting to get rid of the car. We have a 2008 Dodge Magnum R/T package. Roughly 38K miles on the car. When the car reached around 10K miles the rear passenger wheel would squeal when you applied the brake. Rotor surface was smooth as glass. I took off the rear rotors only and had them turned. Problem went away for about 5K miles. Then the fronts started squealing.
I replaced the fronts because hte factory did not leave any material to be turned and noted that Dodge glued the pads to the calipers like they would never need to come off. Problem went away for a little while. Then it came back with a vengeance. I replaced the pad material on the fronts with ThermoQuiet pads from Raybestos. Problem is coming back again and now I cannot tell which end of the car it is even coming from because it it so loud. My wife drives this car very carefully. My thought is she is polishing the rotors too smooth and this is our source of noise.
We are at the point of squealing again and I am at my wits end with this. If I light foot it, no noise. If I stop like I think it should be stopped, not killing it, the noise is there. If I stop very quickly about 3 to 5 times in a row the noise is gone for a little while until the pads cool and then it is back even if I am on the same journey.

I have a 2008 Chevy Malibu. Lately when the engine is cold I will get to the end of the street and when I apply the brakes the car will make a clunking noise and a couple of times it has actually died and I have to restart the car. I only experience this the first thing in the morning, after that the car seems fine. I cannot tell if it is the brakes causing the problem or the transmission.
