2004 Mitsubishi brakes pulse
Allen’s question:
My 2004 Mitsubishi has brakes that pulse when I stop fast. I thought it was the brake rotors being warped, so I changed the brake pads and rotors out. But it’s still pulsing. What could it be?”
Answer:
Well, that normally will fix such a problem, but since it didn’t in your case, here’s the two other common possibilities. First, you could have rust or debris on the hub, so when you put the new rotors on, they aren’t sitting flat. This is called Run Out, and it will cause brake pulsing. And second, make sure the pins on both brake callipers are properly lubricated and aren’t binding, because if they are binding, you will get pulsation. If those two pins on each side can’t slide back and forth smoothly, the brakes will pulse on fast stops.
