I've got a set of Hayes brakes and one of the pistons is stuck on each caliper. New pistons are available, but just wondered if anyone had any removal tips for the old one? Read a few horror stories of people snapping the tabs off the old ones trying to pull them out.

I was thinking of bleeding the brake dry, removing the caliper and splitting it and soaking it in penetrating fluid. Then using a small socket to tap it out?

erm the way to do it is to just pump the brake until it comes out
chances are you will only get one done then
but then put in new one and repeat for other side

dont pull the tabs, at all. theyre really weak
i presume theyre nines?
i had this problem and broke one of my tabs
i ended up smashing the piston apart
didnt seem to damage the caliper

if you do as above, fluid will come out with it
so its handy to have lots spare
and rags

One's moving freely in each caliper, but the other is solid. Think I'll split the caliper and go from there.

Does seem a common issue with Hayes brakes. Yup, mine are based on the 9's :(

yeah sticky pistons

another said method is to part them, then blast some air in their (air compressor i think)

not sure how far you will get by taking them apart
before you do
do you have the plastic bit the goes in the middle when theyre shipped?
so the pads cant move
if so
put pad on the free moving one
then put in the plastic bit

and pump the brake
and see if the piston without pad moves

if that works
you might not even need new pistons
just to put some fluid around it to 're-lube' the seals
as thats what causes this is dry seals
