If all assembled back up it should self adjust the handbrake once the reservoir cap done up and brake pedal pumped till a firm pedal feel is there. With the brake fluid topped up the handbrake on mine didn't need adjusting by me when i did the 4 discs and pads. Until the discs have had a bit of use bedding in they wont be at 100% and the discs will have an anti rust coating to scrub off by braking yet.
