Brakes (A5)Pregunta 51 de 120
The main function of an anti-lock brake system (ABS) is to:
a.Increase brake fluid pressure permanently
b.Replace the parking brake
c.Prevent wheel lockup and maintain steering control during hard braking
d.Eliminate the need for brake pads
Explicación
ABS pulses hydraulic pressure to keep wheels from locking so the driver retains steering control and shortens stopping distance on most surfaces. Wheel-speed sensors feed the control module, which modulates the hydraulic unit. A fault typically turns on the ABS warning lamp and disables the function.
