Since my truck passed 100K miles, I thought it would be a good idea to swap out the pads, rotors, and hubs, as well as replace the coolant and brake fluid. I just tore down one set of brakes and found this:

The outboard pad has about 15-20% wear, and the inboard pad has about 30-35% wear. Here’s the rotor:

Barely any lip worn into it. 106k miles, including a decent amount of towing. I do plenty of city driving (probably 40% city). I would feel like it’s a waste to replace these if the parts weren’t so cheap.
