I was going to suggest putting a piece of wood into the caliper pressing against the pistons and use a G-clamp to press them in. Thats what i did when changing the front pads on my bike but as you say the caliper is on, you might not fit a g-clamp round it. Possibly worth a try though.

They are known for it, pistons seizing etc
I take off the calliper, simples with 2 bolts and use a huge pair of grips to push them back in.
April i bought new seals and pistons, piece of cake to do and lubed it all up with greace, now changing pads is piece of cake. do mine about every 8 weeks, sometimes less.
Front ones about every 4 months ____________________ Nobby the Bastard: How yo tell the difference between the actual japanese and her just screaming because she's had live fish stuck up her arse?

There no room for G-clamp or other kind of thing to work it with? Perhaps if you posted a pic, someone with more experience than me might be able to help

There abouts, i can get 50mpg if i try but average is 42mpg.
Bought it last april 29th on 29,000, took it off road the end of may while waiting for alternator and it's on 93,000.
Using a zzr600 as a temp measure, bought it 2 june, 6 days later i killed it after doing 1200 miles, 10th june back on the road after i put an engine in it and i've since done another 4300 miles in that 2 weeks.
Not great on fuel or tyres but needs must, another 2 weeks i'll have my free alternator. (£500 at dealer) ____________________ Nobby the Bastard: How yo tell the difference between the actual japanese and her just screaming because she's had live fish stuck up her arse?

Indeed lots of miles, although I'd hope to get more than 12,000 miles out of a set of pads, that said I'm one of these boring people who use brakes as a last resort. My CB250Rs is still on the original rear brake shoes after 55,000 plus miles, lots of life left still, second set of front pads, I think, about the third new piston in there though which might be down to me not using the brakes enough or just two many winter miles. ____________________ In the end all comes back to the beginning |

I don't use fronts much unless it's dire need, i ride flat out most the time but plan ahead so don't need to slam on all round at the last minute.
Only changed front pads twice in 64,000 miles, once because they were low and again in april because i was taking it out to Portugal and didn't want to have to do anything to it while out there so potentially have another 60,000 miles in them, plus 280kg bike and fat bastard riding it is a lot of weight to stop from 70mph officer ____________________ Nobby the Bastard: How yo tell the difference between the actual japanese and her just screaming because she's had live fish stuck up her arse?

Lost the thread of the OP's Q here with the debate about mileage....
BUT: Most brake problems start with a pad change, and most often on the backs.
On bikes they either seldom get used, as the rider is front brake dependent, or they get heavily used as they are front brake scared.
Mostly the first, leading to back brake pads seldom getting changed and the pistons corroding a long way out the caliper, between changes.
Then when they do need changing, the piston, corroded and covered in crud gets pushed back into the caliper where the crid & corrosion expands the seal, leading to a seal failure, OR the corroded piston, pushed back into the cylinder working in an are where there is a lot of pitting or corrosion where the seal now is, eading to seal failure.
So my first CAUTION is, if the piston dont want to budge, bite the bullet, pull the caliper off, strip it, clean it, check the pistons... becouse chances ARE they are corroded, and IF you forve it back into the caliper, you are likely to have a seal failure on your hands pretty soon!
If the pistons look iffy, pull them, fit new ones with new seals, fit new pads, put back on bike... job jobbed, well and truly.
HOWEVER.....
If you CAN see in there and can get at and can clean up the pistons to inspect in situ, and ARE confident that they are OK and you AREN'T going to give your self grief pushing them back in.....
Undo the bleed nipple......
That open, piston should go in nice and easily, venting excess fluid out the bleed nipple!
Taking the lid off the reservoir only vents the reservoir to air, you are still trying to push the fluid past the non return valves in the master cylinder!

thanks for all the advice and help. marmalade, many thanks for the offer of helping me! i managed to get it loose after a bit of a clean up, a good push on the piston and it went back into place.
i tried to get the caliper off, but i really cant see any way to do it apart from pulling the axle, it says that in the manual too. maybe i have diferent calipers to yours?
anyway, alls good now, the front pads were real easy but they still had plenty of meat let so ive now got spare pads for the fronts!
cheers
