I'm going to be taking apart a Clarks Skeletal Hydraulic Brake system to try and identify what's wrong with it (trying to remove/unstick a piston), so I was wondering does it matter whether I just disconnect all the fluid cables to the caliper and let them drain, and then do a bleed/refill later?
Most videos I've seen of doing a brake fluid bleed, the system is usually still quite full of fluid, and I can't think of any reason why not but I thought I'd ask whether there's any problems with just emptying the system out.
