Ye back rubs but spins like you say but front spins but stops more abruptly than it should. Definitely not stopping freely.

 Still cant get them free completely.  Think I might have do a fluid change. Due one anyway. Hope that cures it.

Before you change the fluid, you may as well pop the pistons out as far as you can and give them a thorough clean (and lube with brake fluid)
Tinkering is what happens when you try something you dont quite know how to do, guided by whim, imagination, and curiosity.

Could be corrosion in the dust seal grooves, likely assembled dry. This forces the dust seals tight on the pistons, I had it on my Sprint. Stripped them out, cleaned out the grooves, rubber greased the grooves & dust seals, re-assembled, one finger push piston in & others would pop out, best brakes I ever had then.
Careful with orientation of seals.

Bollocks.  Have accidentally pushed one pistons on from brake out to much. Havent came right out but cant be seated right now as wont go back in.  Anyone know what should do. It popped to far as pushing other piston. Dam.

If you are pumping the pistons out and one is free-moving and the other is sticking it's a good idea to use a block of wood or similar to stop the good piston coming all the way out so the pressure shifts onto the sticking piston so they come almost all the way out together ... but I guess you've figured that out now!

If the piston really won't go back in (it's either gone past the seals and they are preventing it going back in or else you're trying to get it back in squint (in which case you might still be ok but don't force them in squint)) then you may have to go back to the advice on your sticking brake thread. Note in that thread my cunning advice not to get stuck with one piston out and one stuck in. Depending on how far yours has come out you may still get away with sliding something in to block the 'outy' piston enough to pump the stuck one out almost to the point it can be pulled out. Alternatively, you may just end up squirting brake fluid past depending on how far out the 'out' piston has already come. As before you can take a view on whether you are happy clamping a brake hose - if you've got braided hoses then don't even try!

One pistons is sliding fine. When I gave that push other one popped nearly out. Now wont go back in. It can be wiggled bit. If seal is stopping it what do I do.
Cheers.

Make sure the piston is exactly in line with the bore. Then push back in.
