brakes pulsate in the front when braking i'm wondering what it might be.my guess is the front rotors need to be changed.i think last time i looked the brake pads were good but rotors were lookin a little rough for wear lol

 

Brake pulsing is a typical sign of warped rotors. Sometimes this warpage can be turned out on a lathe, but many times, the rotors must be replaced - particularly on newer vehicles with thinner discs.

Just for grins, you may want to look at the front end for any worn parts such as ball joints or tie rods.

 

wde 3477 is right on tract, machining is an option only if the rotors have enough meat for turning. By law, and stamped on rotor is the minimum thickness. One turn only please or you are wasting your money. FYI, if in doubt as to front or rears, use emergency brake only to stop. No pulsation, its the fronts.
