Here we have a Yamaha Fazer 1000 front brake problem due to lack of winter maintainence, wht has happened here is the baring surfaces have become erroded leaving large gaps beteen the pads and the bearing surfaces, this allows grit and drirt to become lodged trapping the pads and eventually gripping the dsc.
In this case the vent holes in the dsc were also fully blocked with grit allowing new pads to be ground away in a short period of three weeks.
These calipers are basically unfit for use and will only get worse with time, and need to be changd ASAP to save money on further repairs.
