Ok just bought, foxwell nt510, right now I get some fluid at my rears "but very little" a bit more on the front "Have not gotten any air" . This has new brake lines through out, just can not figure out why just the brake light and a brick hard pedal. My current code scanner came back with dcs failure "but abs light stays off". I know the boosters bad as that part hasn't changed in 50 yrs, so I am pretty familiar with that aspect. .. I am running out of options other then the abs module
