Wheel Speed Sensor: Description and Operation

The anti-lock brake sensor electrically senses each tooth of the anti-lock brake sensor indicator as it passes through the anti-lock brake sensor's
magnetic field. This data is sent on to the anti-lock brake control module. The anti-lock brake control module monitors the frequency created when the
anti-lock brake sensor indicator teeth pass the anti-lock brake sensor to determine wheel rotational speed.
Front
The front brake anti-lock sensor is attached to the front wheel spindle. The front brake anti-lock sensor indicator is part of the wheel hub assembly.
The front brake anti-lock sensors are not adjustable.
Rear
The rear brake anti-lock sensor is attached to the rear disc brake caliper anchor plate. The rear brake anti-lock sensor indicator is pressed onto the axle
shaft. The rear brake anti-lock sensors are not adjustable.
