Have got one of these new-fangled dual flush toilets and the "large
flush" button has a tendency to stick and allow a constant trickle of
water into the pan.

I have no idea how these flushes work - there is a chamber inside the
cistern below the two buttons, and just a length of thin plastic pipe
going to the flush mechanism - for I know they may be all the same or
different makes may use different system.

I have tried spraying WD40 into the chamber from the top by pressing
down the buttons and letting it seep in, on the assumption that the
large flush button is sticking on the side of the chamber, but that
seems to only half a solution. I would welcome some enlightenment as
to how these work, whether I am likely to be able to replace the
buttons, and/or how I can stop the button sticking.

TIA

Is it actually a pipe - as in tube?

As I recall - only having tinkered with one once where the top button was
actually missing and the spring sticking out - the external ring unscrews
the top if you have dry and sticky enough fingers. The central plunger was a
bit fussy as I recall. (The missing button I found a suitable screw wine
bottle cap did the job and looked better than the original.)

_ Yeah - most are a Bowden type cable (alright some are pneumatic) - in
which case the cable could have been damaged or corroded.

just as an aside - funny how people suspect the button when the fault is
more likely to be somewhere else. A bit like pressing the button harder on
the TV remote when the battery needs changing - or turning the ignition key
more vigorously if the car won't start - or pressing the Lift button more
times if the lift is a long time - even though it is lit up..
