What order do I bleed and replace brake hoses?

I am replacing the brake hoses, and bleeding the fluid at the same time. Would the order to bleed and replace hoses be this?

(directions are supposing you are in the driver seat looking forward)
Right Rear: Replace Hose
Right Rear: Bleed

Left Rear: Replace
Left Rear: Bleed

Front Right: Replace
Front Right: Bleed

Front Left: Replace
Front Left: Bleed

Is there anything different I need to do since it has ABS?

I'd replace the brake pads first, then bleed later.

I assume you meant brake hoses. Don't I need to bleed immediately after replacing to get the hose filled with fluid?

Yes.

I think it’s more efficient and less wasteful of fluid to replace all, bleed once. One at a time, you’re chasing bubbles in lines all over the place.

If the system is soft bleed first. If not bleed after each side. You need a baseline to start or else you won't know till after bleeding all four.

Air is only at the end of the line if the system is not soft. Don't want to bleed all at once and discover after the 4th it's still soft. Have to redo all again not knowing which one is the culprit.

Vida says LF, RF, LR, RR with the pressure bleeder, but it makes no difference in practice . The only problem can be if you do it mechanically by pressing the brake pedal right down to pump the fluid through and any corrosion in the master cylinder damages the seal on the piston as it travels down to areas it has never reached before.

I haven't noticed any difference.

Don't forget to remove the caliper and spread the pads to have all of the old fluid out of calipers. Vacuum brake bleeder works best in my opinion. You may also want to trigger inlet/outlet valves of that corner in VIDA to evacuate possible air bubbles trapped in ABS.

I also like the hand pump vacuum bleeder method. Easy, one person process.

I do not have vida and I am using a vacuum bleeder from harbor freight. Would I use the order I put or the opposite one that vida recommends for pressure bleeding?
