Sigh.Here we go again
As this is the closed then shoving the pistons back really isnt going to solve the problem.Its not the standard system so you cant get fluid back into the caliper that way
Try first of all by opening the bleed nipple briefly,if fluid comes out that good but check to see if the pistons move when you do so otherwise youll need to open the lever cap then shove it back.
If you have to do that then you'll have to top up the system before putting the cap back on.
The pistons are on springs and it could be the fluid has expanded,opening the nipple will let the excess fluid escape.Dont touch the lever to pump it out as that will put air into it.If the pistons dont go back then its possible that the system needs stripped and cleaned
when you bleed c2's you dont jam the pads open,let them come out then after refitting the topcap you briefly open the nipple to allow them to spring back
Clear
I would recommend if you need to open the system to use silicon on the sides of the piston,could be theyre a little dry :?
Example-
Screw down adjuster and pull lever.hold lever and apply silicon.
Open top cap-shove back pistons
Refill-Close top cap
Open nipple briefly to drain excess
