I've been dealing with similar issue. could be any or all of the following: warped front rotors, thrust arms (aka upper control arms) unbalanced wheels, misalignment, etc
there are a lot of threads related to this issue...

If its like my wifes 97 528i its what I call the trailing control arms on the front. Hers are shot and its easy to test if thats the problem. Look up under the car while someone turns the wheel back and forth a small amount. You will see the play in the arms where they hook to the body in front of the tire and or at the lower part of the wheel. Its very noticeable if thats what is doing it.

Symptoms are shaking while braking at 30mph or so and higher but otherwise is smooth.

Resurface the rotors, it is about $10 at local auto parts store.

You could try rebedding your brakes. Contrary to popular belief, rotors do not warp. They can, however, get build-up from the brake pads.

I have a different view on the Zeckhausen thingy. His idea is good when dealing with new rotors and pads as one may benefit from "bedding in". People on the internet tend to glorify Zeckhausen thingy. However, after the car has some mileage on it, his idea is basically useless, at least to me.

When a car with some mileage on it has vibration during braking, it is almost certain that the rotors are warped. Yes, rotors do become warped with time.
If one stands next to a brake lathe machine, one will clearly see the warped rotors. Just ask the machine shop to show you the next time you are there.

There is a reason why brake lathe machines are still being made.

Over the course of 25 years of wrenching, after 2-4 years of driving on new rotors, I usually have vibration during braking, after resurfacing the rotors, braking is smooth again.

The bottom line is I find Zeckhausen thingy to be useless.

Bad thrust arm bushing will give shimmy during driving at 50 mph or so.

This thread was about vibration during braking, and in the majority of these cases, it is warped rotors.
