No 1/12 scale cars have brakes, other than what is inherent in the motor / ESC combo. Brushed motors (almost obsolete now, as everyone has moved to brushless) have natural "drag" brake. Brushless motors have much less natural drag brake. Today's ESCs (like the Tekin RS) have settings for drag brake, to provide some level of braking when you let off of the throttle. This simulates the natural braking effect of a brushed motor.
Conversely, the Tekin ESC also has "push control" to apply a minimal amount of throttle to the motor to counteract the drag brake, which allows the car to roll more after you let off the throttle. It's all personal preference as to how you configure these settings in the ESC.
