    Replaced the above but brakes r touchy as heck. No codes and did the linear valve calibration. Is it possible they sent me the 3rd gen kit instead?

    Persistently touchy? I get touchy brakes once in a long while, just after start up, usually in reverse; invariably (so far…) they're back to normal once I get underway.

    It is weird; brakes are off or near-locked, nothing in between.

    Yup persistently. Short pedal mvmnt results in big brake application

    1) Did you give them your VIN when you ordered the part?

    2) Did you use Autel/Tech Stream to bleed and run the tests after the install?

    VIN is absolutely necessary so they can match the correct part number to your exact package car. There's a difference in compatibility especially between stock wheel sizes that can make or break (brake no pun intended) the installation. Good Luck.
