If you find your Lincoln MKC‘s steering wheel shakes or vibrates when you press the brakes, it is almost always the brake rotors that are the cause of the problem.
There are plenty of other issues that can cause the steering wheel to wobble. But, if your MKC is only shaking when braking, that’s a pretty good indication that it’s a brake related problem, and it’s usually the rotors causing the issue.
Why Your MKC is Shaking When Braking
A shaking steering wheel can be caused by many things, such as bad wheels, bad alignment, suspension damage, and damaged tires just to name a few.
With that being said, it’s important to make absolutely sure that you are only feeling the steering wheel shake when you brake. If it’s shaking all the time, but just worse when you brake, it could be any of these things, and a real safety concern.
If you’ve recently had you wheel(s) taken off for any reason (think safety inspection, tire replacement, brake job, etc) make sure that the lug nuts are tightened.
Loose wheels will react to brake pressure and vibrate the steering wheel under braking. This is mentioned because if the lug nuts aren’t tight, a wheel can and will fall off. It’s also quick and easy to check.
1. Guide Pin Failure
Your brakes calipers have something called guide pins. These pins let the caliper move freely, and make sure the brake pad is making even contact with the rotors.
These pins are often overlooked when maintaining a vehicle. They are often covered with a small protective boot. If that boot fails, they can dry up and will stop moving freely.
When guide pins fail, they cause the brake pads to make uneven contact with the rotors. They can also make the caliper stick, which can burn up the brakes fast. This will cause your MKC to have squeaky brakes.
The extreme heat will also cause the pads to “glaze”. This hardening of the brakes will increase the distance needed to stop the vehicle.
Between the potential for the brake pads to hit the rotor at the wrong angle, glazing, and potential stuck calipers, dry guide pins can definitely cause your steering wheel to vibrate when you push the brakes.
The number one reason that your MKC’s steering wheel will shake is warped brake rotors. Rotors can warp if they’ve been worn too low, or worn unevenly.
Warped rotors are even more common today than they used to be. This is because auto manufacturers are constantly trying to reduce unsprung weight.
If the surface of the rotor is not smooth, you’ll need to either have them resurfaced, or buy new ones. A visual inspection will often reveal grooves and unevenness even to the untrained eye.
3. Brake Pads
When the brake pads are operating normally, a pad that is not worn out or dirty is making even contact with the rotor. It distributes the pressure evenly and your MKC’s steering wheel will not shake. The MKC will come to a stop noise free.
If the brake pads are worn past their useful life, or if they are dirty, they will no longer be able to make the quality contact with your steering wheel. At this point, you’ll feel your steering wheel shake as the brakes are pressed down.
Conclusion: Lincoln MKC Shakes When Braking
It is advisable to have your brakes repaired as soon as possible. Warped rotors, dry guide pins, and bad brake pads can all increase your Lincoln MKC’s stopping distance.
This, is dangerous in itself. Good luck diagnosing your shaking steering wheel when braking. Please leave a comment below if there is anything that you would like to add.
