1999 Lexus GS 400 Repair Question
Lexus GS 400 Noise Problem
Its difficult to hear what you hear from here, but it does seem to be unusual. Perhaps the booster will require replacement, I am not sure, but it might be a possibility.

On another site it was suggested that the vac line from the booster might be leaking, or its fitting might. It also suggested I move the line around with sound occurring to see if this could be confirmed. ANy thoughts about this?
