You can take the pistons out one at a time, using the hydraulics to get them out. When the piston is out remove dust seal clean it and the groove it sits in, polish the piston. Lube and place back. If the seals are not maintained, muck and corrosion gets in behind the dust seals causing them to tighten around the piston.

After hours of bleeding like 3 bubbles (stubborn bastards) came out and that seemed to solve the problem but I’ll eventually just take the calipers off and rebuild them out of boredom. Thanks guys

Tie the brake lever against the handlebar overnight. Or upgrade to a nissin mc from a gsxr 600 750 1000 k6 and up. Have one on my srad, now thats what you call brakes ( standard tokico calipers, braided lines ).
