Hi all just removed a siezed all the way in brake piston using a technique which may be of help and uses easily available tools and 2 slices of bread!

Mount the caliper in a vice and remove the Banjo bolt.
Spray some wd40 down the bolt hole.
Stuff the bolt hole with as much bread as possible and then push it in with a suitable rod, taking care of the thread.
Once you reach a point where you can't push more in start taping the rod with a hammer to compress the bread, keep adding bread and hammer it in until your piston is out.
It's not quick and it really does takes up to 2 slices but it does work and doesn't damage the piston.

If you use bread with a high fibre content it will be even quicker

I did and it was seeded lol I don't think white would have been as good.

using your loaf will

Love it everyday is a school day

Nice. I'll remember that.... who on earth came up with that idea? If it was you I salute you sir.

Lately Ive taken to being a bit brutal about it if the pistons won't simply pop out using compressed air and look rough, because its probably goosed anyway.

If new pistons are available I buy them, then check that they'll fit before drilling a 5mm hole straight through the old piston that is stuck in the caliper, tapping an m6 thread, then winding an m6 bolt in to draw the knackered piston out. Quick and easy and doesn't involve wasting tons of grease then smearing it all over the bench, pissing about with special tools that don't work, heating things up etc.

Next time I have a stuck piston I need to save I'll be straight in the bread bin though.
