Can abs cause vibration when braking

According to common lore, a warped rotor is the usual cause for pedal pulsation or vibration in the car or steering wheel motorists experience during braking but, in the cases that are related to the brake system sometimes caused by worn suspension components, the cause for vibration and pedal pulsation is the variation in thickness of the rotor, and not an actual “warp” of the rotor. A failing wheel speed sensor could absolutely cause this issue. If one of the sensors briefly looses signal while driving the ABS module will register that as a wheel lock up and activate ABS braking while applying the brake pedal. This can happen without setting an ABS code and is pretty common.
