Why does my car shake when I hit the brakes? These are just one of the common questions asks by our readers. Since the problem occurs during braking then obviously the problem involves the brakes particularly the brake on the rear.


What happens is that components of the brakes is not in even contact with each other, specifically the brake shoe is not in even contact with the drums when braking and will result to shaking of the entire car. The drums and shoe will not in even contact if there is warpage on the drums. But there is other reason like a worn out or loose rear wheel bearings which cause the misalignment between the shoes and the drums that result to shaking also.

What to do?
Bring the car to the repair shop and ask the mechanic to check the rear wheel bearings if it is loose or worn out, if the bearing is bad replace the wheel bearing, if the bearing is good then the problem is a warped drum that causes misalignment.

If the drum is warped the drum must be machined to correct the warpage, after the drum is machine replace the brake shoe so that it will have even contact with the newly machined drum.
