The brake pedal is still vibrating after the light is gone off. Had brakes repaired, ABS light went out. However, still have the vibrating in my pedal when I brake.
What does this mean?

Hi,

If you still feel the abs engaging, chances are you have a bad wheel speed sensor. If the sensor is sending a signal, even if it is wrong, the light will stay out. The computer doesn't know if the sensor is accurate. It accepts the signal.

Here is what I suggest. There are wheel speed sensors at the wheels that can be checked. You will need a digital multimeter (DMM) to check. Here is a link that explains how it is done:

If you look at pic 1 below, I highlighted the sensors. These are located behind the wheels and will be mounted in the steering knuckle in front and hub assembly in the rear.
