Hard pedal

I have done lots of brake jobs and it never took this much effort. Also I had them of the car when I did this. (painted them). So the fluid had no resistance. had to do one piston at a time. Couldn't use my caliper tool or my (go to) C clamp. Had to use a trailer shackle and bolts and then still effort with the ratchet. The old rotors had wear groves only on the backside of each. Going to look up the special piston tool, an get one. New calipers are 130 bucks each soo.. not end of the world.
