How to free up the front brakes

[gorpracing]

I have an 06 450er. I cant get the front wheels to turn freely. The front breaks drag real bad. I have replaced the pin the caliper rides on and greased them. New pads and all cleaned but will no release and roll free. Help thanks

Pistons in the calipers, need to rebuild or replace the calipers.

Or the disks/rotors could be bent

One of my front calipers did the same thing. I couldn't find new seals for the piston so I just removed the piston & cleaned the seals then put it back together and bleed them.
After doing that the wheels spun freely.

I had the problem after replacing brake pads, front & rear.

Side note: when trying to bleed the front right caliper I found the bleeder wasn't drilled all the way through so had to pull it out & drill completely through to get it to bleed.

seems like using the brake line for bleeding always works best for me and take under a minute, just bleed the brake line end on the caliper
