What is a common cause of vibration during braking?

Vibration during braking is commonly caused by warped front brake rotors. When the brake rotors are warped, the surface is no longer perfectly flat or even, which disrupts the smooth contact between the brake pads and the rotor every time the brakes are applied. This uneven contact creates a pulsating effect, noticeable as vibration in the steering wheel or brake pedal, especially at higher speeds. The warping can occur due to excessive heat from braking, improper installation, or prolonged use. Addressing this issue typically involves resurfacing or replacing the rotors to restore smooth braking performance.

While out-of-balance tires, bent wheels, and issues with the drive shaft may cause vibrations, they would typically present a different set of symptoms or occur under varied driving conditions, not specifically during braking. Hence, warped brake rotors are the primary concern when experiencing vibrations specifically tied to braking.
