As a temporary measure or to test the theory take the pads out and unbolt the calipers one at a time. Work the pistons out (not till they drop) then push them back in. Do this a few times on each piston and it will reset the grab the seals have on the pistons. You should then find that your lost movement at the lever is much reduced.
Voila! Point proved - change the seals. Happened on both my K3 1000's

Rocket - if your theory is correct, shouldn't you be able to "pump up" the brakes as the seals would not return the pistons quicker than you could pump the lever? Ophic said his brakes did not pump up. Am happy to be proved wrong!
