The brakes

The front and rear disc brakes are configured for 
excellent deceleration under braking. New, 
larger brakes will therefore be used in the new 
Passat depending on engine type.

The new Passat still has a Bosch 5.3 anti-lock 
braking system with ESP. This system allows the 
driver to maintain control over the vehicle at all 
times, even in critical driving situations.
