The fluid is topped off. I had an old Jeep that needed the front brakes bled after doing the rear in order to "reset" some sort of safety valve. Do I need to bleed the fronts, or am I missing something else. Thanks in advance!

when this work is done the line to the rear wheel cylinder must be kept plugged up if you allow fluid to drain out air will get into the ABS valve body and cause this. also only work one side at a time.
with a helper and the fluid reservoir at full cap on. pump up the brakes until the pedal is high and hard. then bleed off SLOWLY the right rear cylinder. bleed after 4X times also do not bleed to the point where the pedal is to the floor. then shift to the other side. repeat.
never allow fluid to drop too low. if you do then the master cylinder will require bleeding. also you may need to have the system bleed with special equipment to bleed the ABS .
with what you did bleeding the fronts should be done . also GM does not have a fluid replacement interval . GM is creating lots of brake problems and accidents with this policy. brake fluid does not last forever. most quality vehicles this fluid is replaced after a few years . with this done properly and new drums and fresh fluid you will have great braking power/control.
