Troubleshooting car problems of steering wheel Shakes when braking
The problem that involves the shaking of steering wheel when braking is a clear indication of problem on the front end of your car. The front end is consist of several components that is why sometimes it is difficult to identify what particular parts causes the problem.
However, since the shaking only occurs during braking then we can safely say that the possible reasons is a problem on the brake system and because the involve part is the steering wheel therefore the most probable cause of the problem is within the front brake system but which part of the brake system?
Well, the most common reason for the steering wheel to shakes during braking is a misalignment of brake components, and the components that are often encountered misalignment are the front pads and the rotor disc, when those part is misaligned it causes uneven contact between the two during braking the uneven contact will creates vibration. And since the steering wheel is connected into those components by means of a front ends, therefore whenever there is vibration that resulted from uneven contact between the pads and the rotor the steering wheel is also affected in thus the shaking or vibration of the steering wheel happens also.
Now, why are the pads and the rotor misaligned? Usually when there is warping of the front disc it will become misaligned to the pads, another reason is when there is a worn out or loose front wheel bearings it creates misalignment.
Possible Cause of Steering Wheel Shakes When Braking
Warped Front brake Disc or Loose/Worn Out Front Wheel Bearings.
How to Fix Steering Wheel Shake When Braking
With this kind of problem you have to bring the car to a reputable car repair shop. Tell the mechanic to check the car front wheel bearing for any looseness or wear, if the result is good, then the next thing to do is to check the brake disc for any warped. When there is a warping of the disc the mechanic will probably have the brake disc machined.
But when your brake disc is machined, take not that it is necessary to also replace the brake pads so that it will mate and align to the newly machined brake disc, if you use the old pads it will not be matched to the brake disc thus may create problem. This should fix the steering wheel vibration when braking.
