Why are the brakes on my GM Truck pulsating?
Any help would be greatly appreciated. The ABS – Anti-lock brakes will do this. This problem can be caused by the wrong size tires. Basically the ABS system needs to “know” the size of the tires you have installed. This would be a GM dealer service thing.
