The most likely cause of this condition is B. Front rotor lateral runout. This means that the front brake rotors are not perfectly flat and have some unevenness or warping on their surface. When the brake pads press against the rotors, they create a vibration that travels up to the steering wheel.
Some possible reasons for the front rotor lateral runout are:
- The rotors are worn out or have been overheated by excessive braking.
- The rotors have rust or dirt on them that prevents smooth contact with the pads.
- The rotors are not installed properly or are loose on the wheel hub.
- The rotors are damaged by impact or corrosion.
To fix this problem, you need to either replace or resurface the front brake rotors. You may also need to replace the brake pads if they are worn or contaminated. You should also check the brake calipers and wheel bearings for any signs of damage or malfunction.
I hope this helps you understand the issue better. Do you have any questions?
