The vehicle's hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop the vehicle. For good braking though, both parts need to be working well.
If the warning light comes on, there could be a brake problem. Have the brake system inspected right away.

This light comes on briefly when the ignition key is turned to ON/RUN. If it does not, have it fixed so it will be ready to warn if there is a problem.
When the ignition is on, the brake system warning light comes on when the parking brake is set. See Parking Brake for more information. The light stays on if the parking brake does not release fully. If it stays on after the parking brake is fully released, it means there is a brake problem.
If the light comes on while driving, pull off the road and stop. The brake pedal might be harder to push, or it might go closer to the floor. It can take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle .
Caution: The brake system might not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to a crash. If the light is still on after the vehicle has been pulled off the road and carefully stopped, have the vehicle towed for service.
