1. Warped Brake Rotors. This is the most common cause of a steering wheel shaking while braking. I would say that about 99% of the time a warped rotor is causing your steering wheel to shake when you step on the brake pedal. Most of the time you will also notice a shaking or pulsing in your brake pedal as well.

The word color is the general term which applies to the whole subject - red, orange, yellow, green, blue, violet, black and white and all possible combinations thereof. Hue is the correct word to use to refer to just the pure spectrum colors. Any given color can be described in terms of its value and hue. In additon, the various physical phenomena and pyschological effects combine to affect our perceptions of a color.
