Bosch Brake rotors and pads feel a little soft - bleed or live with?

Just finished replacing 3 calipers an all pads+rotors on 2004 xc70. Replaced 3 of the calipers, so on re-install I bled at least 1L of fluid through the system. Car was never running while calipers were detached from the car but I did have two brake line hanging open (no caliper) for a day or two while waiting for replacemnt calipers to arrive.

The brakes stop the car, but they still feel a little soft. I can certainly bleed them some more. Is the order of bleeding important? Eg, some parts of the manual suggest LF, RF, LR, RR. I didn't read the manual first and relied on the old Saab 900 procedure - bleed the lines from long to short (RR, LR, RF, LF)...

I've been bleeding with a Motive pressure bleeder at 5psi and haven't touched the brake pedal - again, any concerns there? Some posts here talk about accidentally getting air in the ABS cylinder/controller, or bleeding the master cylinder first. I don't really understand what that means - the only bleed nipples I've been messing with are the ones on the caliper.

I'm using Bosch rotors and pads (QuietCast BP794), are they just softer than other options?

If you replace the master cylinder it is recommended you bench bleed the master cylinder before installing. Google bench bleed master cylinder. If you have not replaced the master cylinder this should not be needed - unless you emptied the master cylinder in the process.
There is an added benefit of more bleeding of the calipers - you will get more clean fluid to push out old brake fluid. I often use about a liter per caliper when I do a fluid flush. You want to be sure you are getting clear brake fluid out of each bleeder valve.

Tips if you ever leave brake lines open while waiting...

1. Use a 2x4 wood and wedge the brake pedal halfway down (against the driver seat area), this will stop brake fluid from flowing.
2. Or cap the end using rubber plugs.
