General Car Shakes when braking at high speeds
The main cause of brake judder is a condition called Disc Thickness Variation.

Also had a problem like that on my Mazda. Also had it checked by the experts, and was advised that all was fine. However, I then took it to a different place to check again. They did an "on board" skimming of the disk, and I could clearly saw were the disk was warp. Apparently one of the causes can be that after heavy braking (with the disk warm) it is cooled suddenly, which then cause the warping. (Like driving thru a pool of water.)
Anyway, I was also advised that after the skimming, not to put the old disk pads back, although they were brand new, but rather to put brand new one's on. Reason being that the disk "settle's" on the old deformed disks and will then do the same to the newly skimmed disks. Hope this helps.

Another classic: Drive hard = brake hard. Then park the car and pull up the handbrake. Result: Warped rear discs.
Brake disks don't actually warp. Calling a brake disk "warped" is incorrect. Experience from my motorcycle days, messing about at high speeds resulted in a front end judder more than once.
This will explain it better than I ever could.

I respectfully want to differ from you, they do! Seen it with my own eyes. Even a minuet deflection from the true, will result in judder at speed.
On Morty's point I agree, the heat will transfer to the brake fluid which can actually boil, and not to mention the binding that will take place. Better to park, put in first and wait for the heat to go.
