front calipers not releasing

My front calipers are hanging up. If I pop brake hose on passenger side it release both sides. If I let it sit for about 10 hours, they release their self.

I've replaced caliper, master cylinder,brake hose on passenger side.

I'm thinking brake booster or proportioning valve. Only outside brake pad is froze to rotor. Inside bad isn't touching rotor at all.
Please help

Sounds like the slider pins are not greased and hanging up in the caliper.

They're greased. Both front calipers freeze up. One caliper is new and one factory.

I've bleed them couple different times. Strong clear stream. A mechanic friend said proportioning valve but I think that's his stab in the dark.

Its like they're holding pressure but only the outer pad.

Is inner pad and outer pad the same? Could they ne backwards?

If air is in the rear lines it could migrate into the front during. Operation. I would take to shop where they can put a vacuume on the lines and pull out all old fluid and replace with new fluid then go from there.

I've bleed everything but MC about 3 times. Starting at the pass rear. I just read thread about unhooking brake petal from MC. It was 4 eye stang that did 5 lug converstion. Something about adjustment of a rod? His prob are exactly like mine.
