Brake issue

I just changed out the rear calipers (all wheel disk brakes) on my 98 Blazer 4.3L 4wd. I had poor braking and a real soft pedal. Bleed all four brakes. The braking is better, but still have a soft pedal. There is no leaks, the pedal doesn't touch the floor but close at full braking, and no idiot light on, Any suggestions on this or troubleshooting tips?

ok then you got some air somewhere still in your lines.you cann gravity bleed them just watch resovor don't go dry..open all for bleeders or those have screw in pistons don't they? if so you gota keep pumping them untill piston is little firm. i would try gravety bleed them then go back to pumping up and loosen bletter starting at right side.

Could there be still be air in the line even I used 2 bottles to bleed all 4 brakes? And it is not the screw type pistons.

Bleeding the brakes on it requires a ABS brake bleeding scanner if you let air get into the abs unit.
If you do not have one find a repair shop that does.
A snap on scanner or a GM tech scanner will do the job.
