Front calipers were not touched and the fluid in the entire system is less than 1 year old. Fluid never ran low on the front fluid reservoir during the rear brake job..
Do I need to bleed the fronts?

No, you dont NEED to bleed the fronts, but understand that 99% of brake component failure is due to lack of proper service and maintenance. Brake fluid is hydroscopic, (Absorbs water from air). Many believe it is very important to change your brake fluid annually, biannually at minimum.
So why go through all this effort and not at least "flush" the front half of the system?
