I have my brake calipers Rotors, Pads etc...

they are all ready to put in....ive done pads before, bleed brakes tec...

But this time im intending on doing everything in the same day.

Brake Master, Brake booster, St6ainless lines, Calipers and replace all the fluid in the lines.

How should i go about this...just disconnect everything...apply some compressed air to push all the old fluid out?

Also, what is the best procedure to get all the fluid back into the system...i know i have to bench bleed the master cylinder...but would there be a faster way to get all the fluid into the brake lines than to do the conventional pump pump hold down bleed?

Pressure bleeder.
spend some time breaking the connections to the brake lines. This will probably keep you from completing the task in one day as one of them will be stuck. If you do this before hand, just breaking them loose not loosening them, you will have covered the major stumbling block.

Get a set of the metric tubing/flare nut wrenches. These are six point box wrenches with a cut out side to go over the tubing. Saves a lot head and heart aches with rounded hex heads.

Do not blow the old fluid out with compressed air! Bleeding (flushing) with fresh fluid is the most effective way to replace the fluid and won't unecessarily introduce air into the system. "Bleeding" does not mean "bleeding dry."

Shawn, when I imagine the voice of the character from that avatar coming out of your mouth, vocalizing your post - I can make myself sick laughing.

It really IS you.

What happens when you imagine that character with his bubba teeth?

I took two days to do everything you're doing except the master cylinder

As Shawn so eloquently put it, no compressed air, period! Buy several cans of spray brake cleaner, used in a well ventilated area only.
