As I put my winter road bike back into garage, I moved my Attack Trail MTB, with Hope discs & hydraulics. Brakes were sort of ON, especially rear. Is the hydraulic fluid hygroscopic like car brake fluid, so it's absorbed water & "filled" the pipes etc? The rear wont come fully off no matter how much I unscrew the reservoir cap.

Yes .. virtually identical fluids .. 😉
You may need (I would recommend it) to replace all the fluid, the brake piston seals and any cap / cover o-rings etc
