Default Brake Fluid change ABS Brakes

Need to put new pads in the NM and it's due for a fluid change as well. Trying to get my head around the procedure in the manual..

Front calipers and Accumulator seem pretty straight forward. The rear calipers.. does that mean that simply holding down the pedal, with the ignition on, will use stored pressure in the Accumulator to push the fluid through?

Also, the inner left front pad has worn much more than any other, yet the guide pins seem free enough..

And does anyone know what size tube fits over the drain nipples??

(From the manual)

HBB SYSTEM AIR BLEEDING
If all the brake fluid inside the reservoir is drained due to
the removal and installation of the HBB, bleed air as follows:
Air bleeding from front brake system
1. Turn the ignition switch to the LOCK (OFF) position. Bleed
air from the front brake calipers (right and left) by pumping
the brake pedal.
Pump motor operation
2. Turn the ignition switch ON, and operate the pump motor.
If the pump motor is running free, supply the brake fluid
into the pump motor by depressing the brake pedal three
or four times.

Air bleeding from accumulator system
3. After the pump motor stopped, depress the brake pedal
three or four times with the ignition switch ON. Then
observe the brake fluid in the reservoir. If the brake fluid
looks whitish, wait for a few minutes until it becomes
clear.
4. Repeat step 3 until the brake fluid becomes clear.

Air bleeding from rear brake system
5. While the ignition switch is turned ON and the brake
pedal is depressed, bleed air from the right and left rear
brake calipers.
Caution
(1) If too much brake fluid is drained at a time, the
accumulator pressure may be dropped
abnormally. So limit drain amount at a time to
100 cm3 or less, and check that the pump motor
stops per one air-bleeding.
(2) If the brake fluid level in the reservoir has been
dropped, air may enter the pump motor
accidentally. To avoid this, always maintain the
brake fluid between the MIN and MAX marks.

Air bleeding from power supply system
6. Turn the ignition switch to the LOCK (OFF) position.
Depressurise the HBB power supply system by depressing
the brake pedal several times until the braking effort
becomes high.
7. Turn the ignition switch ON, and depress the brake pedal
quickly twenty times. Then check that the pump motor
stops.
8. Turn the ignition switch to the LOCK (OFF) position.
Depressurise the power supply system of the hydraulic
brake booster (HBB) by depressing the brake pedal until
the pedal effort becomes high.
9. Then turn the ignition switch ON, and then operate the
pump motor. The pump motor should stop within 25
seconds. If the pump motor does not stop, bleed air from
the power supply system again (see steps 6 - 9).

If you still have fluid in the master cylinder tank, just let the system dribble bleed. It is not a good idea to let the reservoir run dry. By dribble bleed I mean undo the nipple on the right front caliper and let the fluid dribble out, the should happen when you undo the nipple a couple of turns, if not, it might be blocked, clean it out with a bit of wire. You may have to give the brake pedal a light tap to get the fluid flowing. Then keep the reservoir topped up till the fluid runs clean. Then do the left front and right rear then left. You do not need the engine running. Dont get brake fluid on your paint work and when you are finished hose off all fluid with plain water. Hope this helps.
