Turning the rotors is basically putting yours on a machine brake lathe and maching both sides of them until the braking area is smooth...The reason you feel the vibration when you brake is because, due to heat, your rotors can warp just like a cd in the sun to long...Using the parking brake alot is a great idea, it helps keep your rear brakes in adjustment. Ceramic pads are the best way to go if you have nice rims, they are supposed to be completely dust free... the reason you get brake dust on your rims without them is because as you wheels spin they create a magnetic (sp?) force, they turns your wheels into magnets, they metallic brake pads create a dust which sticks to the wheels. ceramic pads are non metal so they still create the dust, it just doesnt stick to the rims......As far as rotors go, my personal favorite is raybestos, probably 50 bucks apeice...just be sure that if you have your rotors turned, they also check the minimum thickness specs on them...if they get to thin, they are not turnable, to thin and they will snap in half , ive seen it many times........ok so how do i know all this??? worked 3 yrs at a meineke muffler and brake shop...LOL oh and P.S. i have a 03 silverado 4.8....my friend has an 03 ram hemi...he blows my doors off LOL but mine is 4x4 his is 2x4
