How old is your battery and have you tested it for load and specific gravity?

I had a similar problem which was caused by water under the passenger side carpet causing connectors within the large bundle of wires that runs there to corrode. There are connections within the wrapped wiring itself - something that I did not expect. Once I split it open, there were numerous locations in there that had corroded to the point of, or close to, failure. My proportioning / ABS failure was solved on the passenger side, but I redid the wiring on the drivers side too and found that to be in fairly bad shape also.

Good luck

The battery just replaced last month ago . Alternator charging above 13.5v

I would check wheel speed sensors for damage and clean them off if dirty. Then I would start with the braking system, what is causing this issue? Is it an electric fault or an actual mechanical issue?

Sounds familiar but my car won't run...
