Review on ACDelco 18A1193 Professional Front Brake by Chris Shepherd

Buying "professional" AC Delco parts costs a few euros more. They are usually made to OEM specifications. Thicker brake discs and "varnish" to protect against rust on the non-contact surfaces that are actually left behind after cleaning the brakes. It hasn't come off better with new pads since I bought it years ago. I bought "18A1193" rotors for the front of my 2004 G3500 double cab and chassis wagon.
