Hello everyone, I started taking my Outlaw calipers off today in preparation for a caliper seal rejuvenation, and one thing came to mind that I've never really came to ease with. The last day I was at the track, I was down to my last 25% of pad material and I've always noticed that the part of the pad that gets worn away more is the top edge. So after a while, the pad side profile almost looks like a wedge instead of being perfectly rectangular. I think I understand what's going on here. As the car is moving forward and the brakes are applied, the pad & pistons are dragged downward. When the brakes are not being applied the face of the pistons are parallel to the face of the rotor and pad, but as the brakes are applied it gets dragged downward causing more wear on the top. As we wrapped up and headed home, I noticed that the upper piston on each side of the rotor were stuck in the bores. I believe this was due to how little pad material I had left, how far the pistons were protruding out of the calipers, and that they were getting forced downward. I free'd them up, but still I'm not to at ease with this behavior. I worry that the stainless steel piston will start to gouge the inside of the aluminum caliper over time. Is anybody else experiencing this running a big brake kit (BBK) on a R56 or R53? My calipers are perfectly on center with my rotors. Is this normal or am I correct with my logic? I've noticed that Wilwood sells brake pad shims that would prevent the pistons from protruding so far, but Outlaw does not. I can make my own, but it shows that perhaps Wilwood has thought this out. I've even seen some Lotus folks use this method on their brakes. What does everyone think?
