89,GMC,Safari I replaced brake pads this winter and it worked
fine for a while than the right front caliper stsrted to hang up. So I
replaced the rotor, caliper, and pads today and the brake still hangs up.  
When I installed them I used new caliper bolts and lubed them so that
it will continue to float I cleaned the rotor with brake clean so no
grease should be holding the brake pads to the rotor.  What do you think
is causing that brake to hang up?

Thanks for being so detailed. Without driving the van, sounds like you have a
problem with the caliper hose. With age and mileage, the hose can become
deteriorated inside and not let the fluid which is under high pressure during brake
apply, return to the maser cylinder after brake release. This will cause the caliper
piston to stay partially applied. The way to check this is to have wheel off and on a
jackstand. Apply brakes a few times, release pedal, break loose the hose bolt at the
caliper slowly and see if fluid squirts out under pressure. Not just leaks, but squirts
out. If it squirts, and the piston / caliper releases, then you need a hose, then bleed
that side. You cannot tell by just looking at the hose.
