Changing the nipples, must have introduced air into the system.
A full bleed is a good idea, as its cheap
I think nipples are meant to point upwards  otherwise you don't get the air out the top of the caliper, so make sure left and right were fitted the correct way round.

I did rebleed the fronts when I fitted the new nipples. They are all at the top of the new calipers. Rears are all original.
Braking is getting better slowly but have only done about 30 miles since fitting it all.
Still won't do any harm to do the rears. That's a job for next weekend. 2006 TdV6 HSE.

Bled the rears then re did the fronts and then onve more the rears. Pedal still has some travel but is slowly getting bettet. Only a few bubbles came out of the rears but starting to get better now as now got to bed all the new pads in.
Could notice a slightly firmer pedal straight away after bleeding with a quick test drive. 2006 TdV6 HSE.

Put an old set of pads in the new calipers, (or something which will allow the pistons to be out quite a bit), like a 10mm piece of wood or similar to stop the pistons coming right out. Then, bleed with the pistons extended. With the bleed nipples open, push the the pistons back, thus expelling the air. Tighten the bleed nipples, pop in the new pads, then bleed a bit again. Do this which each nipple/piston set.
This will ensure you have expelled all the air which can get trapped behind the pistons.
If you still haven't got a good pedal, bleed the ABS with iid or similar.
