Check the fluid level in the brake master cylinder reservoir first to pup if required after that I would say codes need to be retrieved from the computer in your car using a scanner to see what area the problem is likely to be in. Low brake fluid may be a sign of a leak but is most likely a sign that the brake pads are just worn.

Well, it could mean that the emergency brake has not been fully released.The ABS system light is on if something has occurred within the ABS system. Something faulty may have happened there, get it checked out!
