Yo, got my car up on my jack and tried turning the front drivers side wheel but the pad is definately rubbing on the disk, I started the engine and pumped the brake a little then let it off and this time I could barely move the wheel at all.. I dunno how the system works but it's like there's no sorta return, nothin pulling the pad away from the disk.. Anyone know what might be causing it?? And how I can get it fixed??
