What could cause the ans light and brake light to come on on a 1993 Chevy van?

The ABS (Anti-lock Braking System) light and brake light on a 1993 Chevy van could be triggered by several issues, such as low brake fluid level, a faulty brake light switch, or problems with the ABS system itself, like a malfunctioning wheel speed sensor. Additionally, worn brake pads or issues with the brake master cylinder could also cause these warning lights to illuminate. It’s important to check the brake fluid level and inspect the braking system for any signs of wear or damage. If the lights persist, a diagnostic scan may be necessary to identify specific fault codes.
