So i had it empty and i had full movement of my lever not hard at all to move. So i reverse filled it with the master cap off and it seemed to work a little bit better as in pulling the lever back easier. But is still pretty tough to squeeze.

Then as to squeeze the lever, you should see the piston come out. It should slide out easily, and smoothly. If it's twin piston on each side one might come out faster than the other. By holding one the other should slide more. Once they are out about 5mm give them a clean with an old tooth brush, and brake cleaner. You should be able to push them back in by hand pressure. Making sure they are straight. If hard to push in there is something wrong.

Ok i have fluid in there now would that make any difference? I guess i kinda need fluid to get the piston to move.

Yes you need fluid to put pressure in the system

Im using dot 3. Would that make any difference? I used the same dot 3 last time and it was fine.

Dot 3 will work. It's not as good as Dot 4 having a higher water content. How old is the Dot 3? When did you open it? It's always best to use a new unopened container if possible.

I would say i opened it in the middle of winter. Its clear and clean. Always sealed. Just need some ideas what to try to get the lever pressure right.

Pull the piston and inspect for corrosion Clean and lube the slides Refill and bleed with fresh fluid from a new sealed container That “abs” restrictor could be full of junk. Usually if the hose is long enough you can unbolt from the “abs” remove the abs from the caliper and attach the hose directly to the caliper. If it still doesn’t work just replace the master cylinder and caliper I’m sure they could be sourced for under $50 Piston location: Slides: 1 888 751 9000

Ok guys i got the caliper off but i cannon get the piston out. At least by hand. I can't push it or pull it. But when i push on it fluid fluctuates in the abs thing. I dont have any brake cleaner so ill have to go get some before i get much farther.

You don't have to take it all the way out. You should be able to pull the lever, and it should slowly come out. You want it out enough so you can see clean metal and no road grime.
