Brake problems, ABS and brake light on.
 

Good afternoon,
(2002 Mitsubishi Montero full)

the brake alarm is on as well, the issue is that I swapped the entire brake unit with another (including accumulator) and the problem is still there. What else can I check? It has to be an electric issue then. My next step is to clean the abs sensors from each tire to see if it does something. I appreciate any assistance. Thank you
