Intermittent ABS warning after 135i front brake conversion on 128i

I recently upgraded my 128i M Sport with 135i front brakes. The brake works great but I am now getting intermittent ABS failure warning which comes and goes. Do you guys have the same problem with your 128i after the 135i front brake conversion? Is there anything I can to to address this?

Did you check the codes that popped up from the warning?

I ran the scanner and didn’t pick up any code.

Does anything feel odd with the brakes? Maybe something got messed up with the wheel speed sensor?

Yes, occasionally, I feel the abs kicks in at very low speed and low brake pressure. I’m on vacation right now. I’ll double check the speed sensor connection. Maybe it got loose when I installed the 135i brake and stoptech brake lines.
