What calipers are these?
As title:
Do these pistons just pull out?
If they're seized tighter than a tight thing, is there a decent way of getting them out other than having them connected on the brake lines?
(i'm still working on the brakes....)
Cheers,
Andy

M16 I had these on the cortina uprights bought a repair kit from big red new pistons (stainless) and seals, I had to use the air line and grease gun
to move them
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

As said above, air line usualy works with enough pressure, just make sure you put some rag around them as they can come out like a bullet once free.

Just a side note, don't try stopping a bullet with a rag.

Oh. and beware vapourised flying brake fluid hurts eyes.

WD40 will only make the seals turn brick hard stick to the piston and make things worse.
WD40 is mainly kerosene like substances use a silicone spray.

Funny I have always understood that its actually fish oil in WD 40, or at least thats what I read. ? Ray

WD40 has a light mineral oil dissolved in something similar to white spirit or kerosene, though WD40's manufacturers are keen to point out it
isn't actual kerosene on their web site.

I have had great success removing a seized caliper piston, by removing the brake pipe and replacing it with a grease nipple and pumping it out with a
grease gun. a g clamp will hold individual pistons as they start to move. a bit less explosive and more powerful than air, but a lot messier.
