hey guys. is the e brake suppost to engage like a normal one nice and smooth? cause when im goin 3mph or faster and pull the e brake its bangs and jerks the car when it barely starts to engage. also, im hearing some kind of metal rubbing sound from the right rear of the car. i took the wheel off to inspect and didnt find anything out of the norm. the brake pads were brand new. maybe its the e brake shoes, but the rotor looks heat spotted pretty bad. any suggestions?
