I have a truck where the brakes have been going to the floor and then it rebuilds pressure right away. I have had the brakes bleed and the problem continues. Can it be the master cyclinder or the abs valve? If it is the ABS system can I disconnect the fuse and will this allow me to see if the ABS system is failing? Will I still be able to drive the truck safely, wife's truck.

 

I think I am having the same problem. It kinda pushes back on you when you push the break down? In fact actually mine now just started the last day or so have the ABS light come on so i'm pretty sure its something to do with ABS... anyone know if this is covered under the longer warranty by ford? I have a 2002 and its out and i really couldnt tell you the details of my extended one my credit union gave me....
