If you have compressed the piston back into the caliper with out opening the bleeders, there is no need to re bleed. If you have opened the hydraulic system you will have to bleed the brakes. To bleed have an assistant press the brakes open the bleeder at the caliper and allow air / fluid to escape. Close bleeder and release pedal. Do this untill there us no visible air bubbles, bleed each brake and don't let the fluid fall below 1/4 full in the resiviour. There is no adjustment on disc brakes.
