I also ordered a few residual valves, brake lines and assorted stuff from these guys. You’ll have to come up with a short list on what you need.
TO NOTE: The brake pedal, pedal assembly, caliper brackets, banjo bolts (shaving), and shock mount position all had to be modified to complete this upgrade.

I wanted to re-post this on the blog so I have it for record:
—————
I figured I would post some early progress shots on my upgrade… for curious eyes. I’ll update this post more as my parts come in and I have more shots.
Shot of booster/MC through the access panel in the cab floor
New brake lines
MC and Proportioning Valve
Where the pedal extension will live
An overall look at the setup from behind
Not much to see here yet
Rotor setup
I am upgrading the following if your curious:
Brake lines and all hardware
Front brakes
Master Cylinder/Booster/Proportioning valve
Pedal assembly
—————-
OK, so I am wrapping up my disc brake conversion and I figured I will post the rest of the shots I just took. Don’t mind the crappy NAPA brake line, I am swapping it for stainless in a month or two.
Shock mounted in new location with custom bracket
New Pedal height Don’t be fooled my clutch pedal is a little loosey…they are the same height
New dual master cylinder and booster, wish i could get better pics of the custom mount
Shot from below of the clutch arm, booster, and pedal assembly for brakes… tight fit.
Dead on shot of pedal and assembly…again tight fit. (tight fit is a theme for this upgrade)
Caliper and mounting bracket (again tight fit). I modified the steering arm and banjo bolt to fit with each other. Had to take some off of each, not a ton. We also modified the stock plate from speedway motos to add a bump stop on the bracket that hits the stock bump stop where the drums hit. This was to accommodate the shocks, even though they were moved they still hit without a stop.
Another shot of the caliper and bump stop on the mounting bracket.
A few things note. I used a 1/4 inch billet wheel spacer to make the calipers clear the stock rims (tight fit, surprised?). Also, the master cylinder *almost* fits perfectly under the stock floor cut out the way I have it. The pedal was reduced in size significantly. It’ll be great when I go disc in the back and this thing stops on a dime.
