Fonz, what's seized up? Those springs?
for more information, when I move my lever, it is completely loose and floppy until 2 clicks in the ratcheting mechanism, then it gets extremely hard to pull any further. Those springs on the calipers might be stuck, causing this?
I didn't specific , but also didnt think it over completely. If the cables are free and springs aren't, you should see the cable move a smidge before the spring prevents it from moving. IF the cables are seized, you likely wont see anything moving. A good working system you should see the cables pull the lever and the lever move, which causes the caliper piston to come out.
Also, put the rear tires in the air and pull the ebrake and verify that both sides are doing something, or nothing at all. Try spinning the wheels by hand with the ebrake up. I've seen many times where one side (cable or caliper) is seized, so there is more slack in the lever because only 1 side is taking up all the slack. It's all just checking the it verifying
