rear brake caliper issue

[Bretty]

I just took my rear caliper off. Which was a mission as It's a bit seized and wouldn't let go of the disk! I managed to drive the pistons out by standing on the lever but now they won't retract.

I'll take the pads out tomorrow and will hopefully get it moving with some cleaning.

I did the fronts and got them running great, then pushed in a couple of the pistons which made one pop out, dumping dot4 all over the place. So they'll need a top up and bleed, but even with air in the system they are still 10times better then they were!!!
