When Car Shakes When Braking

When a car shakes when braking the possible reason is the rear drum and the rear brake shoe is misaligned, if these are misaligned it affects the entire car.


Rear Shoes and Drums is Misaligned
Usually, when the entire car vibrates when the brake is applied, this means that there is something wrong with the rear brake.

What is happening here is that the rear shoes and the drums are not aligned with each other are not even in contact during brake application. If those two parts are misaligned it can cause vibration. Now, why is it that the shoes and drums are not aligned?

Usually, the most common cause of misalignment is a warped rear drum. It is also possible that the rear drums are good, if this is the case then the problem is the rear wheel bearings. The bearings are already worn out or loose. A bearing that is worn or loose can cause an indirect misalignment between the shoes and the drums.

Bring the car to a reputable car shop and ask the mechanic to first check the rear bearings for any looseness or wear. If the rear bearings are in good condition, the next thing to do is to have the rear brake drums machined so that the warpage of the drum will be corrected.

Brake Pedal Vibrates While Applying Brakes
If the brake pedal vibrates only during very heavy braking and if the car has an anti-lock brake, pedal vibration is not a problem, but a normal condition for anti-lock brakes.

Once the drum is corrected, you need to replace the brake shoe because it will not be aligned well to the corrected drums the machined drums must be fitted with new shoes so that both parts will have even contact with each other during brake application to avoid car shakes when braking.
