Passat (B5) :: Loud Thump Coming From Rear When Brakes Applied
Aug 2, 2009
The other day, I was coming home from work. After dropping off co worker, an old man pulled out infront of me. I applied the brakes. As car came to stop I heard a loud thump come from rear. Sounded like i was either bumped by a car, or maybe my entire rear end slid up 5 inches. But that's kinda what it was like. Then after the thump, I put my foot on gas pedal, and instead of car moving forward, the engine just revved. No movement, revved to like 3 grand. I let foot off gas pedal. And tried again. Car moved as normal. Then on the way home i attempted the same combo of rather quick brake and then gas. Same kinda thing happened. Not so hard of a thump. But noise from rear followed by the car no moving, just revving up till i stop and then try again. So even tho my story may suck n my explanation my suck more, whats going on? I just picked this wagon up. 01 glx 65k.

My car is making some noise. The first problem is describing the noise. I think of it as similar to the sound one can make with a moist finger rubbing along the top of a wine glass. A passenger last night thought it sounded like those gadgets you whirl above your head to make noise. I think the noise is coming from the rear brakes. The noise goes away if I apply the brakes. It also goes away if I apply the emergency brake.
It doesn't always make the noise, but it is happening often enough, and is loud enough, that I had to switch from the news to loud music on today's drive to work. I have enough pad left on the brakes, but I don't know about the e-brake. I was under the impression that there are tiny drum brakes that are used as a mechanical emergency brake on these cars? I've never peeked inside. I do have 118k miles on the car.
Maintenance history available at [URL] .... where you can see that the rear rotors were cut at 78k. However, I can feel a ridge on the rotor which I think is where the rotor is swept by the pad. I wonder if this ridge is somehow a problem, maybe rubbing against something else (which will doubtlessly turn out to be now damaged and expensive).

Our excursion usually sits unless we are towing or need to haul a group of people. The past three days my wife has been using it as a commuter. Yesterday she told me that two times at start-up she has heard a loud clunk/thump sound coming from the rear of the vehicle. At first she thought it was happening when she engaged the brake to put it in drive. Today she called me and told me the sound came just after start-up while the vehicle was warming up before the brake was applied. What this could be? I wish I would have observed it so I could give more details.

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.

After putting my Ford Ranger in park and pressing down on the E-break to get the news-paper or mail. I've noticed that there is a consistent squeaking coming from the back drum brakes when the brake pedal is applied. But only for a certain period of time; then the squeaking stops.

A couple of months ago the front driver side of my Sonata started creaking whenever I applied the break. I took it to a local mechanic as well as Hyundai service and after a couple of thousand dollars, it still makes the noise . Both upper and bottom control arms were changed, rotors, pads, brakes, bearings, strut mount, and some other minor stuff that I can't recall...its loud and ANNOYING....

I just picked up a used 2009 LS 460 AWD last week with 45K miles. I have put about 1000 miles on it so far myself.
When I hit any small depression in the road at 10-45 mph I hear a thump in the rear. The bigger the depression and the more weight in the backseat, the louder the thump noise and even an occasional bottoming out feeling occurs. It hasn't happened at highway speeds so far.
The bottoming out feel occurs only with a medium to large depression. I am not talking about a pot hole, just pavement depressions where two sections are not of equal height or you are transitioning from a primary road to a side street and the is a depression to allow for water run off, etc.
If I have someone sitting in the passenger seat and the backseat and accelerate quickly from a dead stop, I get a similar rear thump and even a bottoming out feel. This occasionally occurs even without a without a depression in the road. With no one in the back seat it does not do it unless there is a big depression in the road.
Finally, when cornering on a 270 degree off ramp at 40 to 50 MPH the rear end will start to hop and bounce. If I slow down to 15-20 mph it goes away. Still, it is irritating and embarrassing. I have tried all comfort settings and get the same results.

So today, at a red light, i let off the brakes- I feel and hear a loud pop from the passenger rear. My first reaction, whatever brakes stick, happens.
Then it did it again, then again, a bit louder and a more dramatic feeling. It's my only driver as my TT is out right now in the body shop.

Not sure if normal or a malfunction. Twice over the winter here in MN I have been accelerating and when I hit a icy patch the car made a loud thump/clunk noise loud enough to make be think something broke or that I ran over something like an ice block.
I had it looked at by the dealer and everything is suppose to be working normal. I tried to replicate ite on some ice but the traction control kicks in like normal with the flashing and all. I don't normally accelerate hard so it's rare I get traction control to activate.
Car is TDI SE

On the r32 there is a rattling noise coming from the right rear wheel. It's a very tinny sound and is definitely a metallic noise. The weird thing is as soon as you his the brake, it goes away. Even if you just lightly press on it, it stops. I took the wheel off, looked around for anything loose and found nothing. It's super loud though and completely embarrassing. My e36 bmw does the same exact thing as well and has done so for years, but its much quieter and not as often. On the mkiv its almost constant and at every speed.

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.

So, last week I got my transmission replaced and they also had to replace the CV axle because it was damaged beyond repair when the Transmission self-distructed. They drove it after all the repairs and said it was driving fine, just that it had a belt squeak.
On my way home (30 min drive) about 10 minutes in, still in the city, my brakes start making a grinding noise and sort of a thump thump thump when I brake which sounds like its coming from the passenger side front, it makes me really nervous. It doesn't sound like any brake grindy noise Ive ever heard before and it wasn't making any brake noises before it broke down. (On a side note: it also made a weird noise maybe the first 3 times I drove it after getting it back and I turned the wheel hard to back out of a parking space, that used to be when I heard the belt squeak but I haven't made it squeak since I got the car back.)
Everyone I talked to said it sounded like it needed new pads so tonight I bought new brake pads and rotors for the front and got everything taken apart. The rotors didn't look bad at all, just some light surface scratches, nothing deep, no warping I could see, and the brake pads look almost brand new. I did notice that the inside brake pad on the passenger side was missing its little metal plate that is usually between the caliper and the pad, so I went ahead and replaced all of the brake pads hoping this lost metal plate was the issue.
I also turned the rotor by hand on each side while the brake pads were off and the only difference I could notice was when turning the passenger side one it made a little more noise almost like it was loose.
I got everything put back together and drove around the neighborhood with my boyfriend in the car to listen, the grinding noise was gone and it seemed to brake really well (never got above 30 mph.) However, on my way to return the rotors to advanced auto (45-50 mph) it started making the thump thump thump noise but without the grinding, still on the passenger side. I can feel it in the gas pedal and now it not only happens when I'm braking, but also any time I let my foot off the gas pedal. The only time I dont feel/hear it is when I'm accelerating.

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.

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.

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 have a 2000 F250 PSD. When applying the brakes, the rear end starts jumping and bucking. The effect is exaggerated when pulling a trailer and applying the truck brakes to stop. The problem does not occur when manually applying the trailer brakes. It was suggested to me that this problem is caused by a hydro boost leak.

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.

I am new and just picked up a used 2008 Passat yesterday. It has 42k miles and what I had thought in perfect condition. I wanted to see what was going on before I took it into the dealership to get repaired. When driving I hear a constant whine / (like water is on in a house) type noise. Its noticeable all the time except when the brake is fully applied. It comes back once the brake is depressed and in park. I thought at first maybe it was just a brake pad rubbing but the constant noise in Park confirms its something else.

So I have a 2003 Passat wagon. While driving down the road with no brake pressure applied the front right brake makes a squealing noise. As if the caliper doesn't release pressure....what should I do? Any hints?

I have started hearing a noise with my brakes. First thing in the morning when I back up and apply the brakes, I get a clunk or pop noise from the left front wheel. It will pop again once I move forward and hit the brakes. It only does the noise one time when I first apply the brakes in either direction. Once the brakes have been used out on the road and are warm, there is no noise when changing directions. I've had this noise in another car I used to have and it was caused by the aftermarket brake pads not being exactly large enough and there was slight pad shifting in the caliper. Being this is a new car and has the OEM pads, I would hope there would be no pad shifting or movement in the calipers.

I am having a very intermittent thump/bang/slip in my front end when coming off the highway or taking off at a stop. Believe it or not this is when i drive the car perfectly normal and don't stomp on it which I haven't done much with this car.
I was under the car the other day and noticed neither the dogbone mount bolts looked to have been replaced and i saw the back subframe bolts look to be moving around due to rubbing marks on the subframe.
Car has been in three times to seacoast volkswagen this last time the tech drove with me and they wont do anything because they cant replicate the problem.
I noticed its between 4 to 3rd down shift and 1st to 2nd up shift that it happens so far. It is LOUD and extremely noticeable and feels almost like a slip and heavy bang.
