Hello and welcome to the forum.
No.. it's down to a siezed piston.

You may find that the dust seal that prevents water and other gremlins getting into the piston has been damaged or has just perrished with age. You could work the piston back and forth with some penetrating fluid but without a proper seal it will just seize up again. You could fit a repair kit, strip/clean and rebuild but this is not an easy job. Refurb/exhange calipers might be the best option.

Well if you can get the piston out and the bore cleaned with fine wet n dry (use white spirit) smear of rubber grease...it's refitting the piston/seal and dust cover that's the problem.

bodging around with brakes is not recommended.
Save up and buy a new/refurbished calliper.. (They are not that expensive)
for your families sake.
maybe a little introduction as your going to be here a while.
lots of money saving tips and tricks on 80~90

Have just got in after fixing exactly the same problem. O/S inner piston was stuck in. Eventually got it to pop out, only to discover the seal was in tatters, the bleed nipple was long gone, and despite some wet & dry, the piston was now stuck out!
Ordered recon calipers from Brickwerks on Tuesday lunchtime and they made it to rural Scotland today, superb service (again). Just finished fitting them with a nice new metal pipe to the flexi.
Once I've sent the old calipers back for refund it'll have cost about £140 all in, well worth it.

Thats the way to do it
so if you had fitted it yourself how much would it have cost?

It's always worth replacing the flexible hoses at the same time.
Whilst they may look ok extrenally after 20+ years, they can colapse inside and start acting like a one way valve causing the caliper to bind.
