I have an 06 Z400 while changeing the rear pads I moved the caliper piston out fairly far to grease it and now the piston wont back in. Its like its frozen. Any ideas on what I can do to get in to compress all the way back in. I tired my C-clamp like always but it wont budge!

 

Take the rear master cylinder cap off, remove some fluid (use a clean rag to soak it out) then try it again. Good luck
