mitsubishi triton abs and general electrical problem 

Thank you ML

Brake bleeding first of all. Then you will need scan tool to check your speed sensor reading just incase one is damaged. Go watch my Nissan Navara wheel speed sensor video on the same channel. Adjust rear brake shoes. Make sure all tyre sizes are same. Make sure none of the brakes are seized and dragging the wheel. If none of these helps, you will need a professionals to look at it. Hope it helps.
