i have been hearing alot of wierd sounds coming from my brakes as if i have alot of brake dust on them but lately i have lost alot of braking power, it takes alot longer to stop now. i looked at my rotors and noticed that the brake pads are only covering half of the rotors from what i can see and that is on all four rotors what the hell is going on?? the pads dont look low but i haven't pulled the calipers to take a good look. if anyone can please that would be a great help

 

What do you mean by the pads are only covering half the rotors? Did you matye put a pad in crooked and not notice it? That could be the problem, but you would definately notice that if you looked at the pads.
