brake pedal sticking????

That is a long one. Pull everything; check for calipers/cylinders sticking. Check drum return springs.Check for sticking caliper pistons. No go? Bleed all 4 , you need new fluid anyhow. still no go?Pull m/c, check for under-dash pedal bind. Then a new, not rebuilt master.
It ain't fun. But I would pull lines of the m/c, rags on ports, and step on the pedal, first.
