What issue can warped rotors cause in a braking system?

Warped rotors can lead to brake pulsation or vibration when the brakes are applied. This occurs because the uneven surface of the rotor does not allow the brake pads to make consistent contact with the rotor during braking. As the vehicle comes to a stop, this irregular contact can create a sensation of pulsation in the brake pedal and through the steering wheel, making the braking experience less smooth and more jarring. This condition can compromise the effectiveness of the braking system and can also lead to premature wear of components, such as the brake pads and potentially other parts of the suspension and steering system, if not addressed promptly.

The other issues listed do not directly stem from warped rotors. For instance, increased fuel consumption, engine overheating, and excessive tire wear have different underlying causes and mechanisms not associated specifically with rotor warping.
