Rear caliper piston
I have a 2009 DS450 XCMX - very low mileage - however the past season, with few dune rides i noticed my rear brakes jamming a lot. I serviced the rear caliper and found the rear caliper assembly piston pretty jammed up with sand. i removed it and damaged the seal - now i have been looking to buy the piston kit and couldn't find the right part. looked at the web and order a kit OEM 705600668 as the piston kit for my 2009 but it came out to be twice as big as my original piston.
I have searched the web a lot and haven't found anyother piston kit?! don't wanna spend 230$ on the entire caliper assembly. Any leads,? any one fabricating these pistons? i can share measurements !
appreciate all pointers. see attached pict please.
