Yikes! maybe your brake lines are bad

Your brake lines have failed internally, replace BOTH brake lines and recheck.

Simple, if you opened bleeder screw ,and it is not pluged with dirt, and brakes still wont release CALIPER piston is stuck!!!

Agree, if bleeding brakes allowed fluid to pass through.....at least one caliper piston is frozen. Just figure out which one and replace.
