1+ on TQ's post...did the deed as he did, piece of cake...remember to check fluid level when pushing pistons back into their bores, the M/C may overflow if fluid level was ever "topped up" to compensate for pad wear...otherwise it may overflow the M/C a bit.
At the very end of the day, do the "Overnight Brake Bleed"...Use two bungee cord (to secure the brake lever and foot brakes in the activated position) overnight, the trapped air bubbles will rise towards highest point. Use a plastic or rubber mallet tapping from the furthest caliper piston, up the hoses to the crossover and finally to the M/C banjo fitting. Take the cover off the M/C and check the bubbles as you tap the final bubbles out, releasing the lever/pedal bungees, then pump gently the while tapping, actuating brakes more and more til no more bubbles. Put all back together and makes sure you have strong braking, while bouncing the bike forward to make sure they grab, and repeat for couple more overnighters.
