This kit worked very well for a few months then the steering wheel started shaking a lot when the brakes were applied lightly. This doesn't happen every time so I'm guessing it's not a warped rotor but maybe the pads. The rotors also rusted badly within a few weeks. I'm copying someone else's post because mine are exactly the same. UPDATE I lubricated the guide pins, no help. I swapped the shoes for Wagner shoes, nothing helped. I replaced these discs with a Centric Parts 120.40064 premium cataphoretic coated disc and that fixed the problem. Therefore I do not recommend these Autospecialty rotors.
