Can anyone identify what this hose/fitting is for the on the top of the brake assembly (vacuum line maybe)? I just picked up a used 2012 F250 (has been previously lifted with Fabtech 6") and I noticed that the hose that connects to this fitting was disconnected on both sides, both sets of front calipers. Its almost as if after they did the lift the forgot to reattach them? The pic I have here is after I reattached the line to the fitting. Before I attached it I had no malfunction codes or anything. I am just curious what this is for- is it a sensor line, vacuum, etc? Any help would be great- thanks!

 

Vacuum line for the vacuum actuated locking hubs. That is not part of the brake assembly.

 

So what kind of hubs are on the truck? Should still be OEM...might check and see if the 4x4 still works.

 

Thanks 720Deere! There should have been no reason why they were disconnected would you think? Other than it was missed after they did the lift perhaps, or some other work on the truck? Anyway, I guess I need to make sure the fitting and the hose is not clogged since I have no way of knowing how long they were disconnected? Thanks for reply!

 

Roger that SENIX, it worked when I test drove it, but I am going to recheck again!

 

front hubs might be manually locked in.
