Got a few jobs done on my 2001 1150gs (fuel filter, heated grips repair, throttle cable box lube, brake pads checked etc) While removing the brake pads the pistons wouldn't go back in the calipers on the front, they where free to move as when you squeezed one, the other of the pair would move out so they are free. I don't think they need to be screwed back in like some cars?. Now the bike is back on the road the front brake is very stiff with only a small amount of travel, there also doesn't feel like there is any power to the brakes? Any ideas ?
