WHEN TO CHANGE BRAKE FLUID FOR GM ABS BRAKE? on 1995 Chevrolet Lumina

Some stores use a piece of paper to check the quality of brake fluid, like litmus test. If its color indicates the amount of copper etc. in the brake fluid. But also important is the water content in the brake fluid, which affects its boiling point. So, I wonder when to change brake fluid for my chevy GM 3.1L with ABS system under normal driving conditions? how to tell? thanks in advance

GM has no recomendation as a rule. There is a benifit in changing the fluid. I usally suggest it when doing while serviceing the brake system, replaceing pads, shoes, or calipers/ wheel cyinders.
