You're friends an idiot. I've been using aftermarket pads on OEM rotors (Toyota, Nissa, GM...etc...etc) for over 40 years. Never ever ever had a problem. Toyota uses some special steel??? Oh Please.... Steel is Steel. the major difference in good quality rotors and cheap rotors is the thickness.

fftopic:No your the idiot because i had the prove in my f***ing hand dude you just like to attack people on here like you do all the time here it seems...Are you a Journeyman Mechainc???? with over 25 years of experince and has worked at Toyota for around 12 years???I doubt it....Nope all the stuff with the caliper was fine it was the pads and you could see the damage it had done to the rotors there was a channel worn in to the rotor...You need to stop calling people names and attacking people like that.. Did I call you an idiot NO!! All I did was share my damn experience with this and you feel the need to attack someone you have never met or talked to....People like you give these forums a bad name one of the reasons I left Pirate4x4 years ago same with Toyotatech....:snacker:
That doesn't prove it's the pads...more like a poor installation. Some of these fly-by-night mechanics never take the time to clean and re-grease the pins the rotors slide on...nor do they grease the clips that hold the pads in place. They just remove the pads and slap on the new ones. Doesn't matter what manufacturer...you replace pads that way....5 months is LUCKY.
