Decided to give my front brakes a clean out today on my 1150 GS with Brenbo's.... after removing one of the pads found one of the brake pistons badly corroded... the tiny hole in the centre quite enlarged to about 1/8 of an inch or more. very strange.. 
..anyone seen that before?? They appear to be working ok, but maybe need to think about replacing it.
