I was going about 70mph on the highway during a pretty steady downpour... traffic ahead started slowing down so I hit the brakes mildly hard, and not only did I experience about a 1-2 second delay before the brakes actually kicked in, I noticed also that once the brakes did kick in, my car pulled quite noticably to the right. This had happened before, but I thought maybe I just so happen to hit a puddle while I was braking... but I'm fairly certain that that was not the cause of my experience this morning. Anyone else experience this before? Any ideas what might be wrong? Would replacing the brake pads lessen/eliminate this problem?

New pads (or rotors) will not fix the problem; I've done both. The only thing that will fix it is installing an inner shield behind the front rotors. There's not one available, that I know of.

I could be wrong - but I thought I remember reading that some people have had the problem go away. It seems to be a car to car variation and there is not assurance that new equipment will fix it.

YMMV, but I've been pretty happy with ATE/Mintex in the rain.

The first couple of times in the wet, it was gone. But, it showed up again. At least now they grab fine after the water is "squee-geed" off through the holes. You just have to be aware of it. I'm satisfied with my setup now, since we don't get much moisture in CO anyway. 8^)

As Dave said, YMMV. I guess it depends on the particular car.

driver and drag the brake when planning to stop. Mine take about 4 seconds to dry and begin to grab. After which they exhibit dry braking capabilities. I'm sure it wouldn't be too hard to fabricate (through extensive use of Home Depot) some sort of backing shield to prevent alot of water from reaching the rotor.

When I first encountered the "wet braking problem," it happened only on one side like yours. I had to stop quickly in traffic and almost went sideways. Not a good feeling in a new car.

Like CP suggests below, drag your brakes before stopping, and check them once in a while when you don't need them. My problem seems to be intermittant and hasn't occurred recently, though I still don't trust them.

Regarding the shields, it sounds logical that they would help. However, my motorcycle's disc brakes are just hanging out in the rain, bare and open to the world, and I've never experienced this problem on the bike. (Yes, I ride in the rain.) Hmmm...

I have posted on Mar22. File a complaint on NHTSA site. You will see about 20 complaints. Dealer and Audi say problem doesnt exist. I got run around from both. They say to put on rotor shields at $150. but wont say if they work. Also, since Audi says the problem doesnt exist, will not pay to have shields installed. From what I have read, changing pads or rotors wont work. I am going to drop off car next rain and let service dept say there is something wrong at fix it at audis expense! Or wait till NHTSA takes action, or wait until an accident occurs. Am not very happy with audis handling of this matter. I would put the shields on, but they do not say if it will work or not.
