Ok, so starting work on 5 lug parts

Flair fittings and bleeders are both free (IMG:style_emoticons/default/shades.gif)

pulled hardware, cleaned on wire wheel, pads look new but for price will replace

I tried air gun in flair fitting hole, pistons did not move, what is my next step? Pull the seals and get pliers on the lip?

Do I need to split the halves to rebuild these?

NO - NO - NO !!!

NO PLIERS!
Do not split them!

Guys who do this all the time have a bench-mounted MC and a hand lever to use hydraulic pressure.

Interestingly - the threads on a grease gun are (or mate happily with) the 10mm x 1,0 thread pitch for the brake fitting. So - get a tube of whatever grease is on sale at the FLAPS today and GENTLY use the grease gun pressure to squeeze the pistons out.

Yeah - you need to clean all the grease out. You were going to clean them up squeeky-clean anyway, yes ?
