How would I fix my ABS system so it is not always on and ruining my brakes.

Hi, First off your ABS system should in no way damage your brakes, Normally the main function of the ABS is to keep you from cooking your brakes plus shorting the stopping distance by not allowing you to lock up the tire to ground contact which into turn stop's the car much faster then just sliding the tires. When the ABS light does come on anytime the entire ABS system shut's down and returns to normal brakes and in turn can't cause any damage to the system but also with the light on the stopping distance in a panic stop become longer allowing for more accidents. In "Very very very" rare instant's when someone has worked on an ABS system and not been trained to repair them, they and cause real problem that can go unseen by the ABS module by pressing in the calipers without opening the bleeder and forces the contaminated fluid back up and into the ABS valves causing system damage. As long as the brake work was done correctly you will never see damage to the system from ABS that can cause wear. Depending on your problems I would look for things like sticking hardware and calipers and bad brakes hose holding pressure in one or two corners of the system. With so little to go on I hope that helps.
