LF kelsey Hayes caliper started dragging.

Comon' Man! LoL

I did the easy stuff, replaced Hose and caliper. I should be good to go... No?
It worked great initially, why would the second caliper have the same symptom?
I fear that I'll spend money on the SSBC caliper w/ss sleeve only to have the same result.
Is there something else I should be looking at? Cross over tubes, brake line, Prop valve.

Has anyone else had a dragging caliper not repaired by replacing the Hose or the caliper?
