    Whatever they're called You better be replacing them as a pair like Toyota recommends or you might be paying labor twice just for fun

    Those are the exact noises it's supposed to make. Only a problem if it makes them at the wrong times or too often.

    If that's the case, the problem can still be in either of the two assemblies, so there's no one easy answer what will solve your problem. It's often the booster, as there are more valves inside there to go possibly bad.

    Quick updates:
    I took the gamble and replaced just the booster it work. No more Zzzzz sounds from the pump, only when I step on the brake.
    However, all the ABS, traction lights come on and I did do the bleed job and it work great. Does anyone knows how to reset the lights without scan tools or Techstream tool ? Or let me know which cheap scan tools can do this job ? Please let me know. Thank you

    You can buy a obd scan tool Fromm Walmart and write them down. Clear codes with the tool. If The codes comeback, continue troubleshooting using the codes as reference points

    What did you use to properly bleed the system and set it up?
    You need techstream, or the D7, D8, or some other tool to set it up.
    And that tool will clear the codes.
    Without setting it up correctly, you run the risk of not having brakes.
    And causing a wreck, and injuring some innocent party....

    You did NOT bleed the brakes correctly unless you used Techstream or similar scan tool. That is one reason the warning lights are now on. There are many threads in this forum about brake bleeding after replacing the brake actuator. Do a search and a lot of reading to learn more.

    Here are some basics on doing this with Techstream

    An alternative is to have a dealer or qualified independent with experience in this procedure to do it for you.

    Get dealership to remedy the lights? Keep in mind: they’re not on JUST to annoy you.
