Troubleshooting car problems of car shakes when braking

Usually if the entire car shakes when braking the problem is always the rear brake. The entire car shakes occurs because of misalignment between the brake shoes and the brake drums. When there is misalignment the brake shoe and the brake drums will not have even contact with each other when the car brakes. This uneven contact creates vibrations which is enough to cause the entire car to shakes when braking.

What causes misalignment?

Most of the time misalignment happens because of warped rear drums. Other possibilities is that the drums are not warped but instead the rear wheel bearing is the problem. Rear wheel bearing may be loose or worn-out, if this is the case then the result is a misalignment between brake shoes and the brake drums.
