Disc brakes stuck after bike sitting idle for long time

They don't need to move much. Take the pads out and lube the bit of pistons you can see with some brake fluid (mineral oil or DOT depending on type of brakes.
Push the lever a little to make them move (not too far or you might pop the pistons out) then gently push the pistons back (use something to lever them). Repeat as required until they move freely.I don't do smileys.

thanks.
I can see the pistons move, but apparently not enough.
You think bleeding them will fix my problem?0 -
Has someone put too much brake fluid in. If they have gap between the pads will be smaller than it needs to be.0

Bleeding probably not, as that gets rid of air, which is compressible. Replacing fluid maybe if it's DOT as that absorbs water, which is not compressible.
If they worked before it won't be too much fluid.I don't do smileys.

Happens on my mtb if I've not used it for a while. Removing a bit of fluid sorts it0
