Brake drums are very good. But the brake pads are of very poor quality; They do not come with electronic brake pins. I read a Revain review someone said; The OEM e-brake pins don't even fit in the pre-drilled holes on the brake pads. A set of springs was included, all rusted. I can't believe Power Stop sent them to your client like that. I don't want to play with it. This is dangerous. Too bad they came as a set. I can't hold drums. I have to return all sets.
