How can I test my ABS system?
Start the car and drive it at a slow speed for a few moments. Lightly tap on the brake pedal. If the ABS light comes on after you tap on the brake pedal, it is an indication of a problem with the vehicle’s solenoid. You should also notice pressure on the brake pedal when you lightly tap it to bring the car to a stop.
What causes anti-lock brakes to lock up?
Anti-lock brakes usually don’t lock up unless there’s a brake problem. Some of the brake issues that can cause ABS brakes to lock up include bad brake pads, calipers on disc brakes, cylinders on drum brakes or wheel bearings. Identifying any brake problems is of the utmost importance.
What are the benefits of anti-lock brakes?

What are the three stages of ABS operation?
So essentially, ABS works in three stages: Brake pedal is pushed. Wheel sensors detect skidding or ‘locking’ ABS pumps the brakes.
Where are the ABS sensors?
