Front Brake Seals Melted

[Adriel]

So, since not progressing on the A/C conversion, moved to checking the pads. Make a long story short, several issues:
Rotors hard to move by hand and do not spin freely
No clearance between pad and rotor
Hose had to be pinched, fluid pushed out of the caliper, in order to keep the pads from returning and locking them in the caliper
Pads have 0,2mm of pad left before needing to be replaced
Seals melted onto the back of the pads
Pads glazed

In short, both sides not acting properly and have had severe heat. I can see one caliper sticking, but both?

I have not had recent brake steer, down on power below 40M.P.H., and excellent, meaning above average, fuel economy.

The master cylinder was recently replaced, so confused.

My help says fine, just toss in pads and be done. Is this right?

Thank y'all in advance!
