It may just have been a quality control kit that I received but the rear rotors are not releasing the parking/emergency brake on my 2007 Sequoia. The hub bore size of the rotors also required the use of a demolition hammer for installation, which I haven't had to do on any of the many sets of rotors I've installed on my two sequoias. The car will hold up better with them in place but I had to choose between removing the parking brake pads to keep those pads in place or going back to the bare brake discs which I had before they were at the end of their useful life.
