Most people think of the parking brake as an emergency brake for some reason.  These things are wimpy brakes that are designed to prevent a vehicle from rolling if parked incorrectly or on a hill.  They are generally cable actuated and don&#x27;t have much stopping force if the vehicle is in motion.  The Tundra has a foot-activated ratcheting parking brake and I don&#x27;t recall it ever being referred to as an &quot;emergency brake&quot; in the manual (although it&#x27;s been a while since I read mine, I could be wrong).
