stock. mixed city and highway. all weather conditions. i even tow from time to time 2500-5500 lbs. and as my wife will readily criticize, i like to drive fast.
60.000 Miles (96.000 Km) without changing the brake pads sounds to me like the car was running like on test rack and not driven on normal roads in changed weather conditions (Hot and Cold). The normal Fatigue would have put the brake pads far before the reach of 60.000 Miles to an unusable condition, unless the brake pads would have been made from a super material including high Ceramic compounds and Copper fibers. And I do not even talk about the other brake components such as Rotors, Calipers Hydraulic Brake fluid etc.
For sure the Toyota / Lexus genius standard Brake pads are not made from such materials, because in my cars they brake pads are for gone after 3.600 Miles (5.500 Km)! And this is the reality (see the picture above).
I wish only Toyota / Lexus would sell such a set of brake pads to me that would last 60.000 Miles (96.000 Km). I would even take 20.000 Miles with great pleasure!
