2001 f150. What line off master cylinder is Primary and secondary.


I need to know if line on right that is missing primary or master.

I am trying to figure out what brake line i need to buy we already have it off. It Rusted through and so now i have no brakes. The line has a flexible hose in the middle and connects to the master cylinder. It is either the Primary or Secondary line and i don't know what one is which . Seems to be a ford only part and they want 40 dollars for each part. I found them at rock auto.

The "missing" line is the secondary.

Unrelated but very important, it looks like that truck has not had the cruise recall performed. Unplug that switch above the secondary port and inspect for any fluid in the connector. If found leave disconnected until recall-related work has been done.

Very true with the recall harness!

Would hate to see your house go up in flames if you park it inside.

I would replace the sensor and harness with this:
