hey guys i got a 2001 crown vic. my friend was driving it and he said the abs light popped on when he got home you could smell the brake smoke. i popped the hood and there was no brake fluid. i added brake fluid and the light was still on. how do i unlock the brakes and get the abs light off?

 

Stuck brake piston..jack up the car find the draging wheel and replace the caliper and any other damaged brake parts..will be a fight to get it off but they will come off
