Just bought this amazing car from previous owner. As part of the deal the owner put on new front and rear pads, and new front rotors. When I apply the brakes it feels like there is a low speed pulsation. Some say this is normal for the L46 series? I reached out to a local mechanic who thought I needed all new pads and rotors in excess of $700 to fit the front. I wonder if it is just the brake pads seating to the rotors and the sensation will go away in time. Anyone else have a similar experience?
