Customer states that in wet weather conditions while braking the vehicle experiences a brake loss. Mechanic modified the brakes and found the rotors to be glazed, dealer also installed water shields as per recall, however brake loss still occurs, consumer also states that the ABS does not work well.

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.

Brakes failed while going downhill on a wet but clean road. 58 degrees outside. Pedal felt firm and normal but brakes didn't slow car. 2 seconds of direct pressure yielded nothing. I then lifted my foot and repplied the brake with incredible force. 1 second passed with no response and suddenly the brakes grabbed and stopped the car. Scary.

After sitting for a couple of hours the brakes do not kick in right away if you immediately start the car and back up. You need to push the brake pedal hard and to the floor before the car will stop. Like there is an air bubble in the hydraulics. Many who have driven the car have nearly backed into other cars in parking lots. Fortunately there havenT been pedestrians behind the car when this happened. 2 days after I bought the car I contacted prestige about the problem they said there was no sol the car still has this problem every day. You canT tell if the car is going to stop or whether it is going to roll into something. Once the car runs for a bit the problem is gone. On 3/15/01 I brought the car in & explained the brake problem. The svc agent said this was not normal & they would fix it. The problem was not fixed. On 8/2/01 I brought the car to prestige again. This time I insisted they fix the problem as there had been too many close calls. On 8/3/01 prestige said again it was a known problem & there was no fix. I insisted they keep the car longer to recreate the problem.. on 8/2/01 I called Audi client relations & reported the problem. Audi said they would fix the problem. She assigned case #10530656. On 8/7/01 the svc manager from prestige called & said they had recreated the problem & needed to get Audi involved to get the problem fixed. On Friday, 8/10/01, prestige said they were still working with Audi to get the problem fixed. On Tuesday 8/14/01, prestige left me the following voice mail "I just had a short discussion with my supervisor (dennis). He is in contact with Audi & we are trying to figure out what we might be able to dowhat were trying to do is see if Audi will make any adaptations to that or if there are any other options availablehopefully we should have it resolved it by Friday." On 8/17/01 prestige called & said there is no fix. I need to let the car warm up for 20 seconds before I drive it in order for the brakes to work properly.

While traveling at approxmimately 20 mph attempted to stop vehicle and brakes failed to slow vehicle down. Consumer's vehicle struck another vehicle, causing no injuries. Dealership has not examined vehicle.

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.
