Screw the adjustment screw clockwise with a 4 mm allen key until the pads hit the rotors then back out the adjustment screw counter clockwise 1/3 of a turn. The rear brake pads will have just a little bit of resistance on the rotors as you turn the rotors. Reinstall the bolt that covers the adjustment screw.
