Releasing a seized caliper?

[Craig]

Have a set of rear calipers, they were rusted right onto the disks so had to remove them with a BFH, tried pushing the piston bac into the caliper with my trusty G-clamp, but no joy, I fear that it is seized solid - is there any way that I can fix this, or should I take it down the local scrapmetal merchants?
Cheers

i dont no about on micras but on the primera i used to have you had to turn the piston to make it go in

Same on the K11, you need a sturdy pair of pointed nose pliers to rotate the piston clockwise IIRC. If it sits there and spins and is hard to get back in then they may need a re-build.

I have just replaced both of my rear calipers because the NSR one seized and was causing severe braking issues on the track, (despite a re-build). A new pair was £145 exchange.

Ah, is that why they are a funny shape then?
Will have a play with those soonly.
Any more ad vice is appreciated!
