One thing I used to overlook was the backing plate.  Make sure that the
surface where the brake pads slide on are smooth.  If not, you can grind
them smooth and USE ANTI-SEIZE to lubricate the surface.  If you cannot
get them smooth they should be replaced.

Also check the wheel cylinders by using a power bleeder, fluid should flow
freely at ~20 psi.

Also are the adjusters lubricated with ANTI-SEIZE?

Other obvious parts sould be replaced if worn or old (springs, wheel
cylinders etc.)
