Hope mini mono problems

Hi all, I have decided to pull out an old bike that is fitted with Hope mini mono brakes.
Looks like there are not working so I started to strip them down. After disconnecting the hose, I’ve found that both front and back are pushing but then sucking back. This means I can’t send fluid down the hose. I have completed stripped them down and all seams well. You can see the pistons moving through both two top holes. I tried everything.
Put them to one side for now but has anyone ever experienced them sucking back and not pushing.
Cheers
Craig

So just to add to this post. I have removed the hose and as I pull the leaver in, no fluid is forced out, only air is although the res is full.
As I let go of the leaver, my finger is sucked onto it.
Both leavers are now doing this.0 -
Likely failure of the master cylinder seals then.0

The seals did seam ok and functioning as there should but could be wroth just replacing them both. Only £14 for a re-build kit.
Just found in strange as one was working ok but know I have the same exact problem on both.0 -
I did call Hope and their said that I may of placed the small brass washers the wrong side. So I turned them over and still the same0
