Can anyone tell me where I can find out what the total brake system fluid capacity is for my 2001 F150? I can't find it anywhere.

 

Probably not going to find that if I had to guess. It would vary based on wheel base etc. Is there a particular reason you need this info? Ideally its a closed system, once all air is out of the lines and all components/reservoirs all filled to proper levels you should be good to go.
