A non-skid brake is an essential component of a vehicle's braking system that prevents wheels from spinning on slippery surfaces. There are numerous synonyms for non-skid brakes, including anti-lock brakes (ABS), traction control systems, electronic stability control (ESC), and brake assist systems. ABS brakes work by preventing the wheels from locking up, providing better braking performance and stability in an emergency situation. Traction control systems, meanwhile, monitor wheel slip and adjust brake pressure accordingly, helping to prevent the wheels from spinning. ESC, which is now mandatory on all new vehicles, helps to maintain control of the vehicle by reducing power or braking individual wheels if it detects that the car is losing traction. Finally, brake assist systems provide extra brake pressure in an emergency situation, helping to ensure that the vehicle comes to a stop as quickly as possible.
