2008 F350 SRW 6.4 Diesel.
The brake hydro-boost was leaking fluid inside the cab due to a bad seal. I replaced the hydro-boost with a Reman. unit. Replace the master cyl. also with a new one.
Brakes worked fine for about a week but now after several brake applications, the brakes are dragging to the extent that they getting hot.
I broke the lines loose at the master cyl and pressurized fluid squirted out. After tightening lines, brakes work normal for a while but then start to drag again and I have to stop to release the pressure again.
Dd I get a bad hydro-boost or something else?
Thanks for the elp.
