Why bleed them? There is no need to disconnect the caliper from the hydraulics, just have a piece of heavy wire to hang the caliper free from it's mounting position, so it doesn't hang on the hose. The clamp pushes the piston back enough to insert the new pads. The hydraulic system is closed, so unless fluid has been added during the wear down of the pads, clamping it will just return the fluid to the master cylinder.

The only caution is, since the rear was done a short time ago, if whoever did the the rear, added fluid while the fronts were almost worn out, there might be too much fluid in the system. Depends how they did the rear, but normally they shouldn't have had to break the system either.
