Audi A4 owners have reported 20 problems related to brake disc pads (under the service brakes category). The most recently reported issues are listed below. Also please check out the statistics and reliability analysis of Audi A4 based on all problems reported for the A4.
The contact owns a 2008 Audi A4. The contact constantly heard a very loud squealing noise coming from her brakes. The dealer stated that Audi uses semi-metallic material inside the brake pads and all their vehicles make the same noise when the brake pedal is depressed. The contact was more concerned of the noise, rather than the safety aspect. Neither the manufacturer nor the dealer was willing to assist with the repairs because there were no recalls. The failure mileage was 10,000 and current mileage was 20,000.

I was chasing a brake squeal. When I removed the front pads on our Audi A4, (2001), three of the four pads were not attached to their backing plates. These were the original ate pads; the car has traveled about 38000 miles.

Front brake failure. Out of four pad/shoes, 3 pads physically separated off of their respectivie shoes. One of the three actually came out during driving. When this occured, I temporarily lost braking ability as the brake pedal went to the floor without providing any decelaration. Car needed to be towed to the dealership as it became usafe to drive. The remaining pad/shoe that was not separated was in reaonable condition measuring 7. 7mm (out of 10mm). The two remaining separated pads are chipped showing major delamination and major degredation. Remaining pads & shoes have been saved. Brake pads/shoes & rotors were replaced by ira Audi 97 andover street danvers, MA 978-739-8806 this appears to be a catastrophic product failure once the pad lets loose completely. Events leading up to failure: about a week before, I was hearing a thunk sound when the car would change from reverse to forward motion. This occured only after the vehicle was sitting overnight.
Front brake pads separated from their backing plates.
While braking at any speed consumer heard a squeaking noise. Mechanic determined that the front/rear brake pads fell off.
Passenger front brake pad sepatated from the metal backing plate while within service specification (0. 25 in of pad) and resulted in long braking distances and greatly reduced pedal pressure. Pedal pressure could not be recovered under repetitive brake actuations. The car became unsafe to operate at any speed. There was no warning before the failure. Audi of America refuses to replace the defective part under Audi assured warranty stating that this is not related to a manufacturers defect.

The brakes don't grab when driving in rain, snow, sleet etc. There's a "lag" of a second or two before the car begins to stop. This happens every time you attempt to stop the car in these conditions regardless of speed. There are no brake backing plates on the front rotors from the factory. The rotors are obviously getting glazed with water and the pads are ineffective until the rotors are cleared of water. Makes for a very dangerous driving condition in inclement weather!.

During highway driving in the rain, water develops on the brake pads/rotors, causing the delay in braking. Water buildup seems to occur after about 2 minutes of driving in moderate or heavy rain. Braking delay is about 1. 5 seconds. When brakes grab, they sometimes grap unevenly, pulling the car to one side or the other, until all 4 corners have cleared the excess water. . . Then normal braking response resumes. I have worked as a professional driver, driving different vehicles over long distances. . . This is not normal!!! I know from on-line forums that Audi has not diagnosed the problem, and as such, does not have a fix out yet. I tried replacing brake pads, this did not help.
Front and rear brake pads and rotors failed. Yh.

The wet braking is horrible on this car. If you are driving in the rain, it takes 2 seconds for the rotors to dry out. I have always had cars with 4 wheel discs and have never seen a car that loses its brakes so easily. The car brakes *great* in the dry and when the roads are wet, but when it is raining enough to wet the rotors, all drivers with the stock pads need to be extrememly careful. I don't know if this is part of the problem, but there is no spash shield behind the rotor. I don't want to be involved in an accident because of this and felt like I should report it. I do know that this is not just happening to me, but that is not what the dealer wants us to think. I have heard that changing the pads to an aftermarket helps, but I feel Audi should do something about this before someone gets hurt.
Traveling at highway speed, weather was raining/snowing, when I attempted to apply the brakes to exit the highway, the brakes did not slow the car as they should. I pumped the brakes several times and was able to slow the car for the exit ramp. This has occurred on several occasions prior and since, all during wet conditions. On the 1/22/00 incident, I was on my way to the dealer to have a scheduled service completed and mentioned the problem to the service writer. He acknowledged that there is a problem with wet braking in my model however Audi has not authorized any repairs. He did have the pads removed and cleaned along with the rotors. This has not solved the problem.
This car seems to have a serious problem during wet braking. After numerous occurrences, I was forced to spend $400 to replace the stock pads that may cause this problem. With the new brake pads, no re-occurrence yet. Manufacturer seems inattentive to this. Perhaps NHTSA can contact manufacturer regarding this issue as I'm not the only owner to experience this.

Lack of stopping when brakes are wet. At 1000 mi replaced all pads with german spec oem pads. Wet braking problems neglable. Did not need to wash underware as often.
While traveling consumer heard a noise. The next day, a technician serviced the vehicle and found a part of the brake pads broke off.
There has always been a problem with the braking performance of this vehicle during wet conditions. This is only during highway or country driving where the brakes are not frequently applied. When brake pedal pressure is applied during these conditions, there is approximately a 1 to 2 second delay before the brakes start to retard speed. It feels or seems like there is a film of water between the discs and pads and this hesitation is occurring while squeezing or drying out this film of water.
In wet conditions, the braking ability of this car is reduced. When first applying the brakes, there is a delay before full braking power is available. The theory is that water is being splashed onto the rotors and must be cleared before the pads can achieve full contact.
This car has a long delay during wet braking and I can not figure out why. When they are warm it is fine, but when they cool off such as on the interstate while driving, when they are needed they do not stop the car. In a situation where stopping is needed quickly, this car would not be able to do this in a decent amount of space. I do not have any aftermarket parts on this car, gy eagle rsa tires all new, not original brake pads, 16" factory wheels. This isnt a normal problem like driving through a puddle and braking, it occurs very often and at the worst times, it forces me to drive in the rain and constantly use the brakes in order to keep the warm enough to evaporate water and keep them working.

Braking system does not initially apply any meaningful stopping power when driving in wet conditions. This results in a 1-2 second delay in actual slowing when applying brakes in the wet. This situation has occurred with both stock and aftermarket wheels and brake pads and light as well as heavy wet conditions, and at all speeds.
In heavy rain or slush, braking is severely degraded. It appears that the brake rotors and/or pads act like sponges in wet weather, and can't shed water fast enough during initial braking. A scarey 1-2 seconds will elapse before the brakes, under high pedal pressure, will engage. To avoid the problem, you have to drive with 1 foot on the brake, and 1 foot on the gas to dry out the brakes, then repeatedly check for braking effectiveness.
When driving in wet conditions, the brakes respond very differently than when dry, especially when the brakes haven't been applied for a while. The brake pedal requires much greater force to decelerate at the desired rate compared to what the operator expects based on the experience of driving the car previously. The problem seems to be most obvious when driving on the highway in the rain. I'm guessing a layer of water builds up on the discs or pads (or both), and when exiting the highway and applying the brakes for the first time in a while it almost feels like there is no braking at all! the few times my wife has driven the car in the rain on the highway she has complained loudly to me. The problem is not limited to highway driving, however. Even normal driving around town can result in the feeling of significantly reduced braking. If I drag the brakes a little using my left foot to keep the discs heated up and clear of water then when I need the brakes they seem to be fine. The problem never shows up when it's dry outside. This is very disconcerting and makes me afraid of getting into an emergency situation where I need to deccelerate quickly and simply can't do it. As it is now I have to plan way ahead knowing that I may not have the braking power I think I should have. I have never felt this kind of reduced braking power in the rain in any other car I have ever owned or driven.
