When you bend the brake pad backing plate. Take a look at the pic. You can see where the backer plate has bent. This was my inner left rear brake pad. My right rear is not much better. I am hard on my brakes which in turn creates heat. I have the Steeda big brake kit in the back and the race abs module to help with heat, but looks like I need to create some sort of duct work back there. I melted the rubber boots on the caliper piston and even the rubber boots over the caliper guide rods. Heck, I even have to change the rear axle seal again on that side.
