The 500E used basicly the same brakes as the SL except for the calipers. Won't fit under the small 15" wheels on the 400E.
The ATE power slot rotors are somewhat noisy & axxis pads are the "cheapest" pad you can buy(not close to O.E. quality). Stay with a O.E. quality pad compound!! Make sure to have the brake fluid & system flushed!!
