Why steering wheel shakes when braking?Steering wheel shakes when braking is usually a problem that involve during the application of brakes, specifically on the car front end. Since the occurrence of steering wheel vibration or shaking of steering wheel happens during braking only therefore it is safe to assume that the problem involves the front brakes.

As you may already know the front brakes are connected to the steering wheel by means of front end, and since the two are connected therefore when there is a problem on the front brakes it can easily be notice through the behavior of the steering wheel like the problem of shaking of the steering wheel or the vibration of the steering wheel especially when the car brakes.
Because the brake pad and brake disc is misaligned, it will resulted to uneven contact between the brake pad and the brake disc when brake is applied, thus a vibration occurs. The vibration will then be transferred to the steering wheel and can be noticed when the car brakes.
Misalignment is commonly cause by a warped front disc, other possible reason is a worn out or loose front wheel bearings.
