My recent brake install went pretty well, but it took a fair amount of fabrication to accomplish. I have installed 4 wheel disc brakes on my 51 half ton.
The hardest part involved making a new bracket for the Lincoln Mark V disc/disc master cylinder I used (1 1/16" bore?). I saw the bracket kits advertised in the magasines but I didn't like the looks of the rod end they used to attach the existing brake pedal to the master cylinder pushrod. I ended up modifying the existing master cylinder bracket to allow the Lincoln m/c to be directly behind the brake pedal, just like the stock set-up. I then used a 6" grade eight bolt (with the head cut off) screwed into the existing clevis rod end as the pushrod.
My driver's side floorboard was rusted out, so I welded in new metal from the toeboard to the front of the seat frame. I have an extra battery door that I will cut in above the master cylinder which will allow me to check and service the brakes easily because there is no room to remove the master cylinder lid curently.
I am running 78 Lincoln Mark V disc brakes on the back and CCP's stock spindle disc brake kit on the front, which use 70-77 Camaro rotors and calipers. I am using the stock Lincoln proportioning valve. I ran all new brake lines and new flex hoses. I can say that even without a booster the brakes on my pickup are EXCELLENT. With a pedal ratio of around 10:1 I have more than enough mechanical atvantage to produce enough pressure to lock the wheels with moderate effort. Pushing the pedal halfway down in its travel will result in maximum stopping power.
When I get the battery door cut in I will try to post some pics.
