Mercedes Benz 814D Vario rear brake pads ?

Trying to fit new rear pads to my 2000 Vario. it has the air handbrake. The Capliper has two pistons. Can't get lower piston to retract to allow new pads to fit in. Top piston ok but the bottom one is different. Its the one that works with the air handbrake. Have tried disconectin air. Looks like a piston within a piston? The piston moves out ok to its last postion so I can refit old pads but will not retract to allow new ones Even lossend off bleed to see if that helped.

Any one know??

lower piston needs to be wound back,8mm allen key [you may need to reduce the short side of allen key to fit] with allen key in piston,you may need to carefully push piston back whilst turning c/wise [i think] to engage windback mechanism. hope it helps.
