1 View of brakes system, from pass side, during frame off restoration.
2 Under floor power brake with dual circuit master, from above, showing linkage rod.
3 View from beneath.
Picture taken by using a mirror on the ground to see the view in the camera's lcd reflected in the mirror.
4 Through-the-floor access to master reservoir. Access is covered by a hatch cut from s rusted away floorboard. Diamonds match.
5 Improved system. Sealed with the blue boot, and vented via the black hose. Seems the vacuum booster suck air in, and I though it shouldn't suck in road dirt, mud, crud, slush and sleet.
6 Modification was necessary to the push rod. Needed more length and a disc to accommodate the cut-down universal shock boot. I cut the eyelet off of the push rod and threaded it, while push rod was in place in the booster.
7 Bulkhead fitting. Tig welded stainless, it goes in the floor.
8 Inside the cab, bulkhead fitting, piece of hose, and a generic rocker cover vent cap. Lets in plenty of filtered air, and acts as muffler too.
9 Finished assembly, from right rear. The black heater hose attaches to a tee in a 2 1/4" tube welded to the mounting bracket rear face. The blue boot clamps to the large tube.
10 View from driver's side. 1/2" Heim joint, fine threaded rod, 3/4" diameter rod drilled and tapped for the 1/2" fine rod at each end. I feel the weakest point of the system is the clevis pin at the pedal, and they hold up well.
