A Toyota Owner’s Guide to the Actuator Assembly
Do you have an ABS actuator assembly that needs to be replaced? Or are you simply curious about how an actuator assembly works? You came to the right place. This guide covers everything you need to know about Toyota ABS actuator assemblies.
What Is An ABS Actuator?
The ABS actuator assembly is the heart of your car’s ABS system. It’s a hydraulic part that pulses the brakes when the ECU tells it to. The ECU monitors the rotational speed of your wheels. When it senses one of the wheels locking up, it immediately sends a signal to the actuator. The actuator then pulses the brakes from locking up. The ABS actuator can pulse the brakes much faster than a human can.
