What do you need to know about brake actuator?
It is important to understand what a brake actuator is in order to see how malfunction and failure can have some serious consequences. The brake actuator is basically a relay system that controls the hydraulics of your brakes in tandem with the skid control ECU.
How to know if the brake actuator in your Lexus IS?
The first sign that you may notice is a slight hissing or whistling sound. Since the brake actuator is a closed pressurized system, there should not be any apparent sounds if it is operating normally.
Where is the ABS actuator on a Toyota?
Open the hood and locate the ABS actuator. It’s usually on the left side of the engine bay. Clean off the terminals on the ABS actuator. Start the engine. Connect the ohmmeter ground wire to the top terminal. Check the reading on the ohmmeter.
Why does the actuator lose pressure when you start the car?
This is a result of a leak in the pressurized system allowing the necessary compression to decrease over time. Pay attention any time you apply pressure to the brake. If the actuator is losing pressure, this can be noticeable when applying the brake to start the vehicle in addition to regular braking while driving.

How to tell if your brake actuator is failing?
Under normal conditions, your brake pedal should operate smoothly with no need for much force to depress the pedal. As the actuator begins to fail, you may notice that the pedal is harder to press and seems to require significantly more force to completely depress.

Can a parking brake failure cause brake actuator failure?
Failure, while parked with the parking brake engaged, has also been reported to result in diagnosing brake actuator failure. Most vehicles are now equipped with several warning lights built into the dash in order to alert the driver.
If you open your Toyota’s hood, you’ll find a fairly large squarish part with multiple hydraulic brake lines attached to it. That’s the ABS actuator assembly, and it’s the heart of the ABS system in your car. What Is An ABS Actuator?
Where is the brake light warning switch located?
The light informs the driver that there’s a problem with the base braking system. The brake light warning switch shown is located inside of the combination valve along with the metering and proportioning valves.
