    I recently upgraded my front brakes to 13.3" rotors, so I replaced the dust shields, rotors and calipers and manually bled the brakes. No problem braking, but the skid light, VSC OFF, VSC TRAC, and ABS lights came on. I did a Zero Point Calibration and an ABS light reset, and while I have no dash lights up, the brake assist randomly kicks in when braking, either lightly or firmly. My mechanic used and ABS reader and didn't find any issues or codes. Real-time wheel speed is okay, so no sensor or sensor ring issues. Had to disconnect the fron ABS sensors to deliberately fail the sysytem so I can stop normally.I can't find anything online about the barake assist, a.k.a. Electronic Brakeforce Distribution or EBD. Anyone else have this issue?
