Applicability

Introduction

Small amounts of air in the brake system may cause a squawk or bark type noise from the brake actuator in some LS 460/460L and LS 600h vehicles. If
present this condition is most noticeable when the vehicle is not moving and the brake pedal is depressed or when coming to an abrupt stop. Follow the
procedures outlined in this bulletin to remove any residual air from the system that could contribute to this condition.

This procedure should also be followed anytime the brake actuator assembly is replaced. Refer to the video link below for an example of the
squawk/bark noise condition:
