Lexus LS460 Clicking/Knocking Sound From the Brake Actuator

(56 reports)

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.

Clicking and knocking at a hard stop, actuator or solonoid was first dx, now they say it is a $2300 fix! I took it in before the warranty expired and got a clean report, now 10000 miles later this problem. I thought these were dependable cars. My LS 430 was at 106000 WHEN i TRADED IT IN AND NEVER HAD the first problem. -
A knocking sound is heard from the brake control module/brake actuator when applying brakes, or if the pedal is pressed while the car is stopped. I have been told there was a service bulliten issued 12-2009. Unfortunately may vehicle is out of warranty and currently attempting to get Lexus to do whats right. I have been told the cost of the new revised actuator is approximately $3000.00 -

Clicking when stepping on brakes. Have had brakes inspected by Lexus, they claim that the problems were the control arms. Repaired them. Noise from brakes and poor brake performance continues. -
my han brake is not release -
The braking system feels "spongy"... what I mean is I hear as spring like sound when I apply breaks abbruptly or press firmly while at a stop light. The sound is quite loud. First I thought it was the shocks. Almost like the anti-lock brakes need service. The dealership was familar with the issue and said it was a knocking noise. He said the braking acuator needs replacement and wasn't detected when I had the car inspected 2 weeks before I purchased the vehicle. This is a 5,000 maintenance item Lexus said and I'm SOOOO glad that it's covered under the warranty I purchased. -
