Cruise control and airbag failure after redoing my brakes

I can see why cruise control may not be working because some cars have wheel speed sensors and they may use those sensors for various things like reporting the speed to your speedometer and the ABS system. If you can provide us with the codes it’s giving you either by an OBD scanner or some vehicles will blink the light a certain amount of times in a given interval to tell you the code without a scanner. You can buy a cheap scanner that links to your code or take it to an autoparts store and they might scan it for free.
