I’d like to preface that this is my first build from the frame up and I’m not sure if I’m stupid. My brakes came as a full kit (rotors/caliper). They are flat mount. When the flat brake mount is installed the rotor does not fully go into the calipers and only the outer like 1/4 in is engaging in the brake (see photos). The flat mount adapter is 160/180 – I am using 160 rotors and am absolutely sure I am on the 160 side because when I rotate the adapter the gap to the rotor is bigger. Was I sent the wrong flat mount adapter? Am I missing something crazy obvious?
