Front brakes stuck.

My 09 renegade sat for about a year while I rebuilt the motor, heads, ect. It was in a climate controlled shop.
The brake light was staying on and I had the message across the screen. So I assumed the switch was junk. Come to find my front tires are hard to turn.
I pushed the pistons back in both calipers, cleaned and lubed the side pins. Everything moves freely it seems. The lever has a ton of pressure on it.
I Going to guess the return is acting up in the master, but was curious if anyone has run into this?
