pull ouot the pads and push the pistons back into the cylinder

update: I was tinkering with it and a bunch of either lube or mineral oil, began coming out.

you may need to bleed the system if it’s returning like that. Double check the lever that there aren’t any issues with the brake lever internals – no leaking, nothing getting stuck or slow return when lever is released

One thing I should mention, is that in shipping. The front set of brake had a little red/orange separator, to keep the pads separated (I’m assuming also for bleeds). However the rear set lacked that divider.

so at this point, after depriving it of hydraulic fluid. There is no pressure. So I’m going to perform a bleed once the brakes are installed on the frame, and easier to work with.

Thank you for the help everyone! I’m not going to mark this as solved until I’ve performed the bleed, and confirmed everything works.

Ok if you’re unfamilliar with this type of brake it’s ok dont worry!
1 the caliper is in your hand as if youve just taken them out of the box. if so the spacer is missing and the result is the pistons have advanced.
2 Remove pads and assuming you havent got the correct tool use a nylon tyre lever to push the pistons back.
3 if they bounce back immediately check that the lever isnt depressed
4 if it isnt depressed and the pads continue to extend then undo the bleed port on the lever – press the pistons back in. This should cause a little oil to escape at the lever so make sure its on a rag.
5 fit to bike and bleed if necessary. It frequently isnt.
6 if as you suggest the caliper is leaking, and wasnt shipped with a spacer in place it may be youve got a product that was previously returned. Send it back to Amazon and get a new set.

If you dont push both pistons at same time, when you push one the other comes out. This is probably why you lost fluid at the piston, it came too far out of hole when you pushed the other one. When you push the pistons back in after they come out and leak fluid, the seals frequently get damaged. Make sure you pull the pads and inspect the piston for weepage after a ride or two when you get it installed to make sure the seals are good..
