2013 Lexus LS460 ProblemsClicking/Knocking Sound From the Brake Actuator
A clicking or knocking type sound may be noted from the brake actuator when applying the brakes lightly, or if the brake pedal is pressed while the vehicle is stopped. Our technicians tell us a revised brake actuator is available to correct this concern.
A knocking sound may be heard at idle, when the air conditioning is off and the automatic transmission is in "Drive". Several changes have been made to improve this; a computer software upgrade, revised valve lash adjusters, and a redesigned timing chain are all available to try and correct this concern.
