Quick one for Lee as i'm pretty sure you've stripped the spots out of the brake caliper in the past....
Seem to recall they come out clockwise ie left hand thread, dont want to muller them, stripped in the past without needing to do this but one pot is truly hung up hence the need, tool and new o'rings to hand..

You don't need to unscrew the spots to remove stuck-ish pistons, use pressurized air ... but be careful

Yep thanks Bjorge, i'm well aware pressurised air will remove them but as i dont have an airline and the brakes are dismantled i use my piston pliers but one aint budging..... one caliper sorted, in the morning i'm having an extra weetabix for a replay on the other..

you can unscrew them with a special tool, but they unscrew inwards pushing out the piston so you turn them clockwise.
Compressed air will be your friend but watch out for fingers and eyes.
Wrap tape around lobes of tool to protect the anodised finish in caps.

No compressed air in the house........have the tool for a few years now just never had to use it before but thats just what i wanted to know, clockwise it is thanks..

Crackin tip JMC, never seen that method before but, the calipers are monobloc so i dont think i'll get a ratchet in to do that... might try my tyre inflator to get it moving before dismantling the spots as would prefer not to if it can be helped.

You could always blank the hose hole and fill with brake fluid through bleed nipple and use a grease gun to build the pressure

Haha no grease gun either, i'll take out the spots as a last resort as i have new seals and the correct tool for it..

Why don't you connect one calliper to the master cylinder and pump the tight piston out using the brake lever?
is it Jizzy Rascal time yet.....?

See great minds think alike
Heated the caliper up and then using the piston pliers i put one handle on the table while leaning on the other to ensure a good old grip and moved the caliper instead of the pliers.............many calories later success...both stubborn pistons out..
