Hello everyone, I just changed the rotors on my 2003 gsxr600 and replaced my brake pads but when I put the tire back on and mounted the calipers the front tire barely spins if I spin it with my hand I can do it but as soon as I stop applying pressure it stops spinning and I can hear the brake pads rubbing the rotor, I pushed the pistons all the way down when I changed the pads and the rotors are Driven Sport Series Motorcycle Brake Rotor - Fronts
And the pads are just ebc I have tried bleeding the brakes but their isn’t any air in them to bleed out. Any ideas? Thanks

Sounds like you have some seized pistons.
There are several videos on YouTube which show you how to know if your pistons are seized as well as how to fix them, in most cases you'll have to rebuild the calipers.

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 ).
