That would just cause "loosness" in your steering and wouldn't cause shimmy I wouldn't think since that would be AFTER the source problem.
Sounds like your brakes aren't the issue. i would look into your Steering rack bushings because if they are worn out and dried up, your rack can and will move around when you brake hard causing "shake". if that's not the issue then you may need a whole new rack altogether.
There are only a few things that can cause your shaking.
Warped Rotors....generally shake the brake pedal
Worn Tie-rods..shakes the steering
Severely worn Balljoints(but you'd have to be an idiot for them to get THAT bad as they would be clunking long before)
Worn out Rack bushings(there are only 2 i believe) shakes steering wheel
screwed up alignment but that would cause a few other issues as well.
I have turn on the engine.
And turn fast the steering wheel from left to right.
When i made this, my friend can feel a jerking on the wheels.
I think the steering is the problem.
But how can i check this?
Or do i have to replace the complete Rack and Pinion Unit?
