I have noticed my 05 SC430's brake fluid increases overnight. Would some of you please help to verify with your SC430 and see if it does the same? I suspect that it may be something wrong with brake system because I checked my 08 RX350 and it does not do that. The picture 1 below shows the brake fluid level when I park the car in the evening when I return home and picture 2 shows the level in the next morning. Thank you in advance.

it is normal…when you turn the key on, engine off or on, you will hear the pump turn on, which applies pressure to the brake system.
this is my 2007.
