Still need to know the year and trim of your 4Runner to answer...
The 01/02 brake system is an electrically power hydraulic boost system that can make noises, especially when it is wearing out.
The earlier ABS system can/does make a quick noise soon after the brakes are released after startup. That's normal.
The Limited auto-AC servos can make noise if there are problems.
The auto-antenna can make noise when the radio is powered up.
