Been sitting for over a year during build/rebuild. with wheels off-turned when last moved. Now pads are stuck Disc. 6ft bar doesn't move the wheel. Can't move brake adjuster. Have removed canister so there is nothing pushing on them. Have tried penterating oil. Hitting with hammer. Long bar jack against lug. pads are $227 per side and both sides are like new and both are stuck. Have tried releasing parking brake and appling service brake many times to brake bind. Front are same set up and did not stick. Also caged parking brake and removed whole assembly. Seams funny both stuck. and both had just came several hundred miles after I purchased and rolled just fine. I backed into shop for 18 months took wheels off and rebuilt everything else now they won't turn. Surface rust is visible but sands off easily.
