I HAVE BEEN HAVING A LOUD BARKING SOUND NEAR THE DRIVER SIDE LOWER SIDE NEAR OR BEHIND THE FIREWALL. THIS OCCURS REGULARLY WHEN BRAKING AND EVEN OCCURS WHEN I DEPRESS THE BRAKE SO I CAN TURN THE CAR ON. IT MOSTLY HAPPENS WHEN NEARING A COMPLETE STOP AND PRESSING THE BRAKES MODERATELY. THE PEDAL WILL EVEN VIBRATE LIKE A CELL PHONE WITH NOISE. THERE APPEARS SLIGHTLY REDUCED BRAKING RESPONSE AS THIS HAPPENS ALTHOUGH NOT MUCH. IT SOUNDS LIKE OLD PIPES WITH FLUID MOVING THROUGH IT BUT SHARPER. VERY DISAPPOINTING FOR LEXUS.

THERE IS A NOISE THAT MANY OF THESE VEHICLES SUFFER AS A SYMPTOM FROM A PROBLEM IN THE BRAKE SYSTEM. IT PRODUCES A HONKING OR GRUNTING TYPE SOUND WHEN FIRM PRESSURE IS APPLIED TO THE BRAKE PEDAL.

Therefore, the actuator pumpwill buzz every few seconds trying to keep pressure in the braking system to a safe operating level of gas pressure,to no avail due tothisleak inthe accumulator. After it quits buzzing, say shutting the car off, you can hear the air leak “hiss”pressure away. as you may know tons and tons of articles on this issue online as this is a major safety concern. Many have had Toyota replace the part free of charge as well due to the extended 10 year, or 150k miles, in whichever comes first. warranty.
