I was driving a friends 2017 F550 diesel truck the other day.
37000 miles on it.
He told me be sure to pump the brakes.
Every time I needed to apply the brakes the pedal went to the floor, second pump the brakes seemed fine.
I did a lot of reading about Ford trucks having this problem.
Some have had the master cylinders and boosters replaced. This did not fix the problem. They were told that's just how it is.
One fellow has had his truck to 4 different dealers trying to get this resolved.
I have read about adjusting the "pushrod" that actuates the master cylinder.
Other have removed a spring in the ABS control module.
Your thoughts?

Yeah that's a problem. They start making everything so damn complex. Used to be there was just a brake master cylinder, a booster and then the fluid went to the wheels. But now it's got all this ABS crap. I would assume it's an ABS system failure and the only way to accurately figure that out is with a bi-directional scan tool the cost of fortune and do a bunch of testing on the ABS system
Thank you for the reply.
Truck may still be under warranty.
