Has anyone else had fitment issues with Carbotech brake pads on the Model 3 Performance?
I have a 2021 M3P (Fremont factory, July 2021 build date) and purchased Carbotech AX6 front and rear pads through Martian Wheels. The brake pad part numbers that I received are correct (CT83752FP-AX6 / CT83752RP-AX6), but there are fitment issues on both the front and rear. My local shop here in Fremont, California helped install the pads.
The front pads make loud clunking noises the first time I brake after changing directions. Reverse out of a parking spot and brake "clunk", shift into drive and brake "clunk". Basically it seems like the front pads have some room to move around inside of the calipers.
The rear pads would not fit into the calipers at all. We had to re-install the stock rear brake pads for now. First, the narrow portions at the end of the backing plates were too wide by around 1mm. We ground those down to fit inside of the calipers, but then found out these pads are at least 1.5mm thicker than the stock pads. Even with the pistons fully pushed back, there was not enough room between the pads to fit the brake rotor.
Has anyone else encountered these problems? Could the brake calipers have changed to a new design recently?
