Hello. The ABS light on the dashboard is an indicator to warn the driver of improper system function. With your symptoms, I believe your anti-lock braking system controller may have a fault. The anti-lock braking system measures wheel speeds and the differences between them to try to anticipate lock-up and prevent this by pulsing hydraulic pressure through the system. Have a certified mechanic, like the ones at YourMechanic, inspect your braking systems hydraulic and electrical components for faults.
