The parking brake holds the car stationary, when the driver's seat is empty, by mechanically locking/blocking two wheels.
Foot brake - anti-lock braking system
The anti-lock braking system, ABS (Anti-lock Braking System), prevents the wheels from locking up during braking.
Brake fluid - grade and volume
The medium in a hydraulic brake system is called brake fluid, and it is used to transfer force from e.g. a brake pedal via a master brake cylinder to one or more slave cylinders, which in turn act on a mechanical brake.
The foot brake is used to reduce the car's speed while driving.
Foot brake - emergency brake lights and automatic hazard warning flashers
Emergency brake lights are activated to alert vehicles behind about heavy braking. The function means that the brake light flashes instead of - as in normal braking - shining with a constant glow.
Foot brake - emergency brake assistance
Emergency brake assistance EBA (Emergency Brake Assist) helps to increase the braking force and so reduce the braking distance.
