Ok, not from my 4Runner, but a good example on why you don't buy cheap brakes. At the time I was a little strapped for cash and bought the $18 dollar rotors and the cheapest ceramic pads they had. That was last summer. Anyways, was getting a lot of shudder when braking so I swapped out the fronts a couple months ago which helped a lot but you could still feel the rear shake. It got a lot worse pretty quickly so I finally got around to doing the rear this last weekend. I've never seen a rotor come out looking like this. I don't care how broke I am I will never go for cheap brakes again.
