parking brake light and ABS light come on and off from time to time on 2003 Dodge Ram 2500

Today, out of the blue, the parking brake light and the ABS light came on. No sooner, they went off again. It seems to happen when I'm going slow and turning to the left, or idling and turning the steering wheel.

Sounds very much like the brake fluid level is low in the brake fluid reservoir . Low fluid may be due to worn brake pads or a brake fluid leak some where so it should be investigated further.
