hi. i changed my rear brakes today which was easy but after i was done (and yes i pumped the brakes and everything is fine) i noticed that the wheel doesn't turn smooth.

i took the wheel out. still the rotor is hard to move.
i took the brakes off and i think i found the problem (but dont know how to fix)

its like the ebrake inside is touching the rotor a little like i pressed the e brake half way but not all the way and has nothing to do with the new brakes.

i can drive with that but it gets really hot.

please help me fix it i spent like 6 hours trying to fix it. i have to drive somewhere tomorrow morning so i must fix it tonight.
tnx.
