Mercedes ML W164 ABS Fault

[PROJUMPER]

ABS & Engine management light just came, I parked at a local store, when I tried to pull off it sounded like the back brakes where grinding and staying on, I noticed the ABS light was on, I pulled over and tried to take off again, and it feels like the n/s brake is holding on, any suggestion?

Most likely a wheel speed sensor has gone down. They can make it grief to get moving when they fail.
