problem details
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 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.

the pedal feels like i have 120,000 miles on the front rotors the car is driven on the highway most of the time i am shocked, my BMW first set of pads was at 75K, my GL Mercedes at 60K, how can this be?
Car accelerates when I press the Brake pedal slightly. Cruise control does not cut off when Brake applied lightly to slow for aproaching vehicle. The Car is now in the shop but they believe it is the brake actuator
