Brake lines look great, the truck has never experienced the Michigan salt...., keep my TV in the garage during the Michigan winters, or in the Texas Hill Country as I'm doing now.

Almost did it this year, but needed to replace my grocery-getter....., may pull off the the new F-350 next year.

The following pic's (taken in the last hour) are of my Hydroboost/Master Cylinder assembly. The hydroboost unit is mounted to the firewall, and the brake master cylinder is mounted to the hydroboost. You can see how the power steering fluid has been blown back (engine fan) covering most of the hydroboost unit, and little fluid covers the back area of the brake master cylinder:
The source of the fluid is from a 'weep hole' located at the bottom of the hydroboost mounting flange where the master cylinder mounts to the hydroboost. Apparently as the internal seals/o-rings fail the hydroboost fluid will leak out the weep hole.
My understanding is that the hydroboost uses the power steering fluid pressure to function. The hydroboost unit replaced the old big vacuum canisters that use to be mounted behind the master cylinder......, guess the newer engines don't give off enough vacuum.
When the hyperboost fails it then directly impacts the operation of the brakes and power steering.
Below is a good "how to" link and shows how challenging the project can get if one wants to rebuild their own hyperboost unit (not me).
