[Closed] Shimano Road Hydraulic Calipers

I have what are definitely RS-505 levers and I think BR785 calipers on my Pinnacle Dolomite 5.

I've had two sets of front pads get contaminated very quickly so suspected leaky seals. I've been in the garage today to have a look and the pistons are stuck out solid (even with the lever bleed port open), though do move out. In trying to push them back in I've managed to chip the piston, so if it wasn't already knackered, it is now.

So question is, are the last/current generation mountain calipers the same? They certainly take the same pads. Like [url= http://www.chainreactioncycles.com/shimano-deore-m615-disc-brake-caliper/rp-prod112313 ]this[/url]?
