Brake Fluid Replacement at 40K miles

Recommended Posts

Why does Lexus recommend replacing brake fluid at 40K miles for my 2014 RX350? Is this something new?

Per the 2014 RX350 maintenance manual at the following link, brake fluid is to be replaced every 30,000 miles or 36 months whichever comes first: RX 350_WSG_lr.pdf

That seems odd since the braking system on our 2014 Toyota Sienna is virtually identical as is the braking system on the Toyota Highlander.  Changing the brake fluid on the Sienna is not in its maintenance schedule and is considered "lifetime".
