    Can you narrow down frt or rear sticking? Could be anything from frozen pistons to bad hoses to MC.

    Calipers not releasing is usually restricted flex hoses to the calipers. Replace the hoses. They fill up with flaked off rubber and will stop brake fluid flow back to the master cyl.

    In my experience, this is most often a seized caliper more so than a hose.

    Either way, don't replace either blindly. Try turning the caliper piston in. If it's difficult, try it with the bleed screw open. If it moves with ease when the bleed screw is open, replace the hoses. If it is still difficult, replace the calipers.

    And he's talking bout the REAR calipers. I was referring to the fronts sticking. Front calipers sticking..... usually hoses. Rear calipers loose, rattling..... seized pistons in the caliper from non use of the parking brake over a prolonged period.

    You MUST follow the adjustment of rear calipers by the book. The pistons in the caliper must be ratcheted out to take up normal wear clearance. Then lastly you tighten the parking brake cables. The levers the cables attach too on the rear caliper must be at rest against the cast in stop on the caliper with the parking brake fully released. If not, the caliper pistons will not ratchet out as designed as you use the parking brake each and every time you park the car! Most rear caliper issues come from non use of the parking brake. Pads wear, then pad clearance increases then the caliper rattles. There is a special tool that allows the piston to be ratcheted out assuming the piston is not already seized.
