Formula OroK18 replacing brake pads issue

Hi guys,
I managed to neglect my brake pads to the extent where the front ones wore down to the metal - not a good thing - makes a bad noise!
Anyway, I changed them last night and came across a slight issue that hasn't happened before.
Because that pads were so worn, the pistons were quite far out. As usual, I carefully pushed them back into the caliper to the point where they were flush with it. I then inserted the new pads. I think that the pistons were ever so slightly creeping back out, but by very little. I'm using relatively cheapy Superstart components pads, which seem to work fine, but........when I came to insert my front wheel, the pads were so close together that they were applying braking force to the disk without any brake being applied.
I have replaced my pads several times in the past and this has never happened. Does anyone have any ideas why this happened and how I can stop it? I hope I don't need a brake bleed as I'm going away this weekend and have no time to do it.

There might be too much fluid in the system. I have never done it with Formula brakes but heres a quick dodge to get the pistons all the way back (you need at least 3 hands for this)
Take out wheel and pads and using a broad tyre lever or something similar push both pistons back at same time and hold the pressure on both pistons then using your 3rd hand just crack the bleed valve open a tiny bit you should feel the pressure on the pistons drop and the pistons slide back flush then without releasing the pistons shut the bleed valve. As I say never done it on Formula brakes but have done it on Avid brakes which are the same system. Refit pads test brakes thoroughly and you should be good to go.
If you crash and break yourself I offer a full 60 second warranty

Thanks stubs, that makes sense. I'll give it a shot!0

as stubs says.
you have too much fluid in your system from moustre absorbtion through the seals or a mid pad wear bleed. It wont be the pads0
